Tips for Extending the Life and Getting the Most Out of Your Pavement

wet cast tiles

Longevity in home design is a precious gift, and your concrete paving blocks are the one thing you hope will perform well.

Though it’s a much stronger and ostensibly durable material than asphalt, concrete will still crack and wear out over time. Once the instant fresh laid hot paving block starts the cooling process, it starts to age and becomes vulnerable to the wear and tear of use and environmental factors. You can, however, significantly delay such effects with proper maintenance.

Driveway paving blocks, along with other paved surfaces need good maintenance and care in order to have it last as long as possible.

From the moment it cools, the pavers start to break down from exposure to oil, gas, heat and cold extremes, sun oxidation, salt corrosion, water penetration, pressure and impact damage, and other factors.

rubber paver moulds

When your concrete pavers are properly installed and maintained, it should last for decades.

Certain environmental intrusions, such as aggressive growth of tree roots or earth shifting, can cause cracks, but otherwise, your patio floor will remain intact for years and years.

Paver blocks typically survive longer than regular concrete because it has more protective coatings. They usually include a color hardener and a sealant applied to the surface, which protects it better from wear and abrasion.

These tips are designed to be a handy reference to help you with preventative maintenance on your paved surfaces, whether they are residential or commercial. Many factors contribute to the proper maintenance of a concrete patio. This guide discusses some useful tactics for preserving yours.

  • The less direct interaction your paving blocks have with the elements, the longer it will last. So you can extend the life of paver blocks by a few extra years with a canvas patio cover or pergola. You might desire this addition for looks and comfort anyways, so the protective aspect makes it more worth the investment.
  • Take the time to carefully inspect your pavement on a regular basis and watch for any major cracks, fading of painted markings, signs that point to wear and tear and the signs that repair work may be needed soon.

    plastic mould for paver tiles

  • Keep your pavement clean; ideally, you should take a pressure washer or standard garden hose with a spray attachment and wash away dirt, debris, or other foreign contaminants every week or two. You can also use liquid dish soap and a broom to scrub away spills or bird poop, then rinse with a garden hose. If the concretegets stained by grease, food spills, or something else, try to clean up the spill as soon as possible.
  • Seal coating definitely helps in slowing pavement deterioration and is useful on driveways, parking lots, and other surfaces. The sealer will also preserve the shine and color of the blocks. For maximum benefit, the standard recommendation for reapplication of sealer is once every two or three years, but if you notice the color fading or the sheen disappearing, you can have it reapplied sooner.
  • The sealant on concrete paver is designed to resist strong elements and normal wear and tear. Certain heavy-duty chemicals can corrode it and eliminate the sheen prematurely, however. Products that contain ammonium nitrates and sulfates are particularly harmful because they’ll attack the concrete directly.
  • All car and foot traffic must be kept off surfaces that have just been sealed for a minimum of 24 hours to allow ample curing time- this is critical to ensuring the paving blocks are not weakened or damaged from the start.
  • Proper attention to the tile cracks and early patching of minor issues will prevent them from growing into major headaches and will be cheaper in the long run as well and will extend the life of your pavement.

    automatic brick making

  • Tree and bush roots can compromise the integrity of your concrete if you don’t manage it properly. Roots will grow beneath the paving bricks, push it up, and cause it to crack. You can avoid a substantial cost of repairing with preventive measures. Have the roots in your yard trimmed regularly so they don’t endanger your pavers. You might also need to remove trees that develop extensive root systems to avoid future problems.
  • Fixing areas of ponding water as soon as possible reduces any chance of water seeping through and weakening the base and limits the formation of potholes and even worse the creation of sinkholes.

Why we should use polypropylene plastic moulds over others?


Polypropylene sometimes referred to as pp mould is a thermoplastic “addition polymer” produced by blending propylene monomers. It is a synthetic resin used in a variety of applications to comprise packaging for consumer products, special devices like living hinges, plastic parts for various industries including the automotive industry and textiles. It became prominent extremely fast. Polypropylene has the ability to crystallize. Polypropylene is utilized in both household and industrial use. Its distinctive properties and capability to adapt to various fabrication techniques make it stand out as an invaluable material for a vast variety of uses. Another invaluable characteristic is polypropylene has the ability to function as both a plastic material and as fiber.

We, JR Rubber Industries, paver mould manufacturers use this safest and highly beneficial polypropylene plastic for our products. We have the complete solution for exterior flooring industry with the manufacture and supply of moulds, the supply of paver machinery, setting chemicals and colour oxides and complete technical assistance for paver production with in-plant training and onsite assistance for production.

Uses of polypropylene in different industries

The major end users of polypropylene are the packaging industry, electrical and equipment manufacturing, household appliances, automotive industries and construction materials. Relative to other common plastics polypropylene has a low density ranging between 0.895 and 0.92 g/cm which translates to weight savings for manufacturers and distributors of injection moulded polypropylene parts. It has extraordinary resistance at room temperature to organic solvents.  Polypropylene can be easily copolymerized (essentially combined into a composite plastic) with other polymers like polyethene. Copolymerization changes the material properties remarkably, allowing for more robust engineering applications that are possible with pure polypropylene. The ready availability and relatively less price make polypropylene a beneficial component for the mould.

Some of the most significant characteristics of polypropylene are:

1.Chemical Resistance: It is a good choice for containers of such liquids, such as cleaning agents, first-aid products since diluted bases and acids don’t react readily with polypropylene.

2.Elasticity and Toughness: Polypropylene will act with elasticity over a certain range of diversion, but it will also experience plastic distortion early on in the diversion process, so it is generally reviewed as a “tough” material. Toughness is defined as a material’s capacity to deform without breaking.

3. Fatigue Resistance: Even after a long torsion, bending and flexing polypropylene retains its shape. This property is especially beneficial for making living hinges.

4.Insulation: It is very useful for electronic components since polypropylene has a very high resistance to electricity

5.Transmissivity: Polypropylene is normally produced to be naturally opaque in colour although it can be made transparent. If a transfer of light is important and is of aesthetic value polypropylene can be used for these applications. Polycarbonate is better choices if high transmissivity is desired.

The Different Types of Polypropylene :

The main types of polypropylene available for production are homopolymers and copolymers. Among them, homopolymers are the most commonly used and general purpose moulds. The copolymers are further classified into block copolymers and random copolymers. Each type suits certain applications better than the others. Polypropylene is sometimes called the “steel” of the plastic industry because of the various ways in which it can be recast or customized to best serve a specific purpose. This is normally achieved by adopting special additives to it or by making it in a very particular way. This adaptability is an important attribute.

Properties of polypropylene

1.It has the melting temperature at 130°C

2. The typical injection mould temperature ranges between 32 – 66 °C

3. Heat Deflection Temperature (HDT) is maintained in 100 °C at 0.46 MPa

4. Have a Tensile Strength of 32 MPa

5. The flexural strength is kept at 41 MPa

6. Have specific gravity of 0.91

7. Shrink rate is 1.5 to 2.0%

The mentioned properties help in the efficient production of perfect plastic products. For the giving satisfactory result to our customers, we always opt the best of everything. And that is why we use polypropylene in our plastic products. We have different variants of plastic paver moulds including natural stone, zigzag, I shaped, hexagon and many others.

What Should Be Preferred – PVC paver moulds or Rubber mould?

 

PVC moulds

Rubber moulds and PVC moulds are widely used all over. The physical and chemical properties are quite different from each other but rubber and PVC alone possess its own characteristics.

Different types of moulding process are casting, injection moulding, blow moulding, compression moulding, rotational moulding.

rubber paver mould

Know more about Rubber…

Rubber exhibits its own unique features and physical properties. Mullins effect and Payne effect are the stress-strain behaviour exhibited by rubbers. It is often moulded as hyperelastic. Rubber block suppliers comment rubber strain crystalize. Natural rubber is pliant to vulcanisation and delicate to ozone cracking due to the presence of a double bond in each repeat unit.  Turpentine and naphtha (petroleum) are the two main solvents for rubber block manufacturers in Indonesia. Since 1764, the former has been in use when Francois Fresneau made the discovery. In 1779 Giovanni Fabbroni lifted the discovery of naphtha as a rubber solvent. The rubber material is finely divided by shredding prior to its immersion, it does not dissolve easily. While rubber is transported from its collection site an ammonium solution can be used to prevent the coagulation of raw latex. Expansion and contraction property of rubber make it stand out from other materials.

The moulding process of rubber is like pressing a block of rubber into a rubber molding metal cavity. By activating a channel reaction the rubber is then exposed to heat. Usually, allrubber block suppliers use heat and pressure method to form molded rubber products. Compression molding, injection molding, and transfer molding are the three rubber moulding process.

paver making

  • Compression moulding is done by inserting a sheet inside the mould. It is the simplest moulding method. The rubber is forced to take on the shape of the mould by pressing the two halves of the rubber into the sheet. It is the crudest and oldest form of rubber moulding. In the final stage, it often produces rubber pieces with errors in the final shape. The advantages of compression moulding are:
  1. Best for small production
  2. Good for big parts
  3. Low costing tool
  4. The material doesn’t have to pass through gates, runners or sprues.
  • Injection moulding is heated until it has a toothpaste-like consistency. It is the most precise way to shape rubber. Injecting into a mould the rubber is allowed to harden. Rubber paver mould concrete casting in Cambodia create strong rubber pieces in this way. They retain the exact shape of the mold with few inconsistencies. The advantages of injection moulding are:
  1. Minimum wastage of material
  2. Flexibility in colour and material
  3. Fast production
  4. Labour cost is low
  5. Design flexibility
  • Transfer moulding is a mix between injection moulding and compression moulding. A large slug of rubber is placed into a pot in this process. More than compression pieces the rubber pieces made by transfer moulding possess high quality but it is less than injection pieces.
  1. When compared to traditional compression molding they have shorter production cycle times
  2. Advantages for coloured or translucent compounds
  3. Supports high precision molding applications
  4. Over-molding and molding of complex geometries are supported in closed mould transfer.

Plastic Pavers Mould

Get a little information about PVC..

PVC is one among the category of thermosetting plastics which can be softened by heating. PVC is the material which is long-term resistant to degradation and oxidation. In Europe, PVC is usually used for flooring, artificial leather, and decorative sheets. It is a natural resource derived from 57% chlorine and 43% carbon. This is an excellent resistant to fire, splintering, decaying, and insect infestation. Because of its cheap rate they are often used for drip edges, kick-boards, table boards. PVC is used for interior as well as exterior applications.

Properties of PVC

    1. Mechanical property

PVC cover blocks possess high hardness. Its mechanical properties upgrade with the increasing molecular weight but it gets decreased with increase in temperature. Rigid PVC possess very good mechanical properties, 1500-3000 MPa is the range of elastic modulus and elastic strength of soft PVC is 1.5-15 MPa.

2. Thermal and fire properties

Since its heat stability ios very low it needs a heat stabilizer during the process to ensure the product’s properties. When the temperature reaches 140 °C PVC starts to decompose with melting temperature starting around 160 °C. It has good flame retardancy. The LOI(linear oxygen index) is minimum(up to 45 or more).

3. Electrical properties

The electrical insulating property is subordinate to non-polar polymers like polyethylene and polypropylene because of its higher polar nature. It is a polymer with good insulation properties. It has high dielectric loss tangent value, dielectric constant, and volume resistivity but poor corona resistance. Generally, it is packed for low frequency insulation materials and medium or low voltage.

4. Chemical properties

PVC is used in sewerage piping as it is resistant to salts, acids, fats, bases, alcohols. uPVC and plastified PVC are less resistant to solvents. Some are resistant to fuel and paint thinners. May some solvents expand it or distort it but not liquefy PVC. Whereas some may damage it like acetone or tetrahydrofuran.

pvc moulds for paver blocks

  • Different types of PVC
  1. Rigid
  2. Flexible
  • How is PVC made?

PVC moulds for paver blocks in Kuwait are extracted from three emulsion processes. They are:

1. Suspension Polymerization

It is a heterogeneous ultra polymerization process that uses mechanical commotion to blend the mixture of monomers. It is one among the widely used polymerization techniques. Purification and processing of the polymer is much easier than compared to emulsion polymerization. Here, the final product is a 100% solid resin.

2. Emulsion Polymerization

Like vinyl acetate, vinyl chloride, chloroprene, acrylamide, acrylates, and methacrylates it is the most important methods for the polymerization of a large number of monomers. It is rapid than bulk or solution polymerization at the same temperature. Harkins proposed the first hypothesis of the mechanism of emulsion polymerization.

3. Bulk Polymerization

Over other polymerization techniques, mass polymerization has several other advantages. As the final product is 100% solid resin it is a very environmental friendly polymerization which does not require any purification method. Because of the lower heat of polymerization and reactivity, this is much more suited for step-growth polymers. Depending on the solubility of the growing polymer chains in the monomer they can proceed either homogeneous or homogeneous.

A Pure Steer To Plastic Moulding

Pvc paver moulds

Do you know how to get it made a custom plastic part or product? This article will guide you to choose the right type of moulding process available today to help you to discover the real process for your project. It doesn’t matter how small or large, round, square, or weird shape, flexible or stiff, already mould or not?

What Is Plastic Moulding?

Moulding can also be spelled as molding. It is the process of manufacturing by shaping liquid using a rigid frame called a mold or matrix. A powder or liquid polymers such as polyethylene or polypropylene is placed into a hollow mold when moulding plastics for the polymer to take its shape. Various ranges of heat and pressure are used depending on the type of process used to create an end product.

Does Plastic Moulding Possess Any History?

In the late 1800’s plastic moulding began to fill the need for plastic billiard balls. John Wesley Hyatt in 1868 invented a way to make billiard balls by injecting celluloid into a mould. To automate the process four years later Hyatt and his brother invented and patented the machine. Paver block machine in India, plastic moulding uses a basic plunger to inject plastic into a mould through a heated cylinder, the first plastic injection moulding machine in existence.

James Hendry, in 1946 invented the screw injection moulding machine. This replaced the plunger injection technique and it is a widely used method even today. In 1855 modern rotational moulding also has a rich history when rotation and heat were used to produce metal artillery shells in Britain.

In the early 1950’s plastics were introduced into the process when rotational moulding was first used to manufacture doll heads. The modern process of rotational moulding allows us to create large hallow containers with low-density polyethylene in the late 1960’s. Plastic powder developments, better equipment, process improvements have sped up the process of creating finished products and provide a path to the rapid growth of rotational moulding.

Which are the different types of plastic moulding?
Most popular techniques in plastic moulding are:
1, Rotational Moulding
2, Injection Moulding
3, Compression Moulding
4, Blow Moulding
5, Extrusion Moulding
6, Thermoforming

  • Rotational Moulds Are Highly Customizable And Cost Effective

    The moulds can be remarkably knotty to ease the moulding of a wide range of products. Pathway mold can incorporate curves, inserts, and contours as well as logos and slots for metal inserts or plastics to be placed after a product is moulded.

    Than injection moulds or bow moulds tooling costs are lower with rotational molds. The common uses for rotational moulding are:

1,  It is highly knotted to facilitate the moulding of a wide range of products.
2, To make large hollow plastic products like storage tanks, car parts, utility carts, pet houses, recycling bins, playground slides, road cones, kayak hulls, and marine buoys is what rotational moulding
3, It has lower start-up costs and runs as a cost-effective production when producing as few as 25 items at a time.

  • Injection Moulding

    Making custom plastic parts by injecting molten plastic material at high pressure into a metal mould is the real process of injection moulding. After the molten plastic is injected into the mould, he mould is cooled and opened to reveal a solid plastic part just like other forms of plastic moulding. Paving block machine manufacturers in India suggests this process is somehow similar to Jello mould, which is filled then cooled to create the final product.

The common uses for injection moulding are:

1, Injection moulding is used for making very high volume custom plastic parts.
2, Large moulding machines can mold car parts.
3, Small machines can produce very precise plastic parts for surgical applications.
4, Plastic resins and additives increase the flexibility for engineers and designers.
5, PP mould is used in injection moulding for a wide range of applications.

As steel and aluminum are the raw materials for making an injection mould for spacers in Bahrain they carry a hefty cost. But, the cost per part is frugal if you need several thousand parts per year. Tooling with injection moulding usually takes 12-16 weeks with upto four more weeks for production.

    • Blow Moulding

      It is a method of making hollow, custom plastic parts, thin-walled. With a uniform wall thickness, it is primarily used for making products also where the shape is important. It resembles the same principle as glass blowing. Blow moulding machines inject air blowing up the hot plastic like a balloon and heat up plastic. As it expands the plastic blows into a mould and it presses against the walls of the mould taking its shape. The part is ejected when it is cooled and hardened after the plastic balloon fills the mould. An average of 12 hour day can produce around 1440 pieces because the whole process takes less than two minutes.

      The common uses for blow moulding are:
      1,  In most cases, it generates plastic drums, fuel tanks, and bottles.
      2, This is the best process if you need to make hundreds or thousands of bottles.
      3, It cost less than injection moulding.
      4, Blow moulding is fast and economical than injection moulding.
      5, Sometimes it is as high as 6 to 7 times as much as a roto-molding tool.

      plastic moulds for interlocking tiles

    • Compression Moulding

      It is done exactly as its name suggests. A heated mould is filled with a heated plastic material and then pressed into a specific shape. The heating process ensures that the plastic retains maximum strength once the plastic is compressed into the right shape. Wet cast tile moulds in China says cooling, trimming, and removing the plastic are the final steps involved in this process.

      The common uses of compression moulding are:
      1, Replacement of metal parts with plastic parts.
      2, Most commonly used for small parts and products in very high volume.
      3, This moulding type is used by the automation industry
      4, Its final products are very strong and durable.
      5, The opening cost of a compression mold is persistent.
      6, The cost of each individual part is low at high quantities.
      7, They are ideal moulding for large quantities of parts.

    • Extrusion Moulding

      Expect a long continuous shape extrusion moulding is similar to that of injection moulding. Another specialty is that in extrusion moulding,‘die’ is used instead of ‘mould’. By squeezing hot raw material through a custom die the extruded parts are made. To get the plastic resins into a mould for spacers in Nigeria, other forms of moulding use extrusion. This process ousts the melted plastic straight into a die. The shape of the final product is determined by the die shape.
      The common uses of the extrusion moulding process are:
      1, Extrusion parts have a fixed cross-sectional profile.
      2, They should retain the same along the length of the part.

  • Thermoforming

    Its manufacturing process is what a plastic sheet called thermoplastic is heated to a pliable forming temperature. Paver block production in Cambodia trimmed to create a usable product from its specific shape in a mould. It comes in varieties of colors, thickness, finishes, and materials.

In order to achieve the final product thermoforming uses several different types of moulds and processes. A single 3D form made out of aluminum is used to create 3D products. Moulds can be produced for a low cost using inexpensive materials, thermoforming uses low pressures.
The common purpose of thermoforming are:
1, Used to manufacture thin-gauge containers, lids, disposable cups, trays, blisters, clamshells, and other food and general retail industries.
2, Vehicle door and dash panels, refrigerator liners, and utility vehicle beds are the results of thick-gauge thermoforming.
3, To get a thermoform ready grass pavers mould in Malaysia takes an average  of 8 weeks and its cost is purely based upon the size of the part.

Get To Know About The Full Structure Of Bricks

Brick mold

Bricks are used as building material for pavements and construction of houses. In India, the brick mold were used only for building to fit bricks to make houses in rural India, but now with the modern architecture bricks are also used to create pathways these days in India.

It is clay that helps in the brick making in the old days, but now there are bricks made of concrete, metal and many other materials. Soon the material became a decorative item rather being used only for sidewalks.

Brick making in Uganda is an art practised for a long time. The use of bricks in Uganda can be easily found as it was a rural area once bricks like fire brick, half bricks and quarry tiles are most of the bricks uses in Uganda. There were times when bricks were cheap when bricks were the only type of floor tiles and wall tiles we had in our house.

Bricks are used by most construction industry as it the most durable and affordable material, different types of bricks offer you with different types of benefits, used for different purpose and according to the job.

Types of Bricks-

  • Common Burnt clay Bricks


    Pressing molds helps to create common burnt clay bricks. Dried and then burned in a kiln. These are the most found common bricks, they are mostly used for building and are not the type of bricks that you would use for decoration.
     

  • Sand-lime Bricks


    Sand mixing with fly ash and lime with a chemical process helps you create a sand-lime bricks. Later the mix is shaped into a brick which is used for construction compared to clay bricks having a grey colour compared to the usual red, no plastering is required as their shape is the same and it also offers a better durability has also established itself a strong hold brick.

  • Engineering Bricks


    Manufactured in very high temperature, unlike other bricks. These engineering bricks offer you durable bricks that provide you services like water absorption, limit strength and more. Mostly used for the construction of tall skyscrapers and buildings, with all these benefits you should know that it is also costly compared to other bricks.
     

  • Concrete Bricks

    In India concrete paving stones and bricks are found much more compared to other, made with solid concrete and found most common brick for house builders.Unlike, other bricks you don’t get a fixed colour, you got options on concrete bricks, the color that you can select while the production of the concrete brick.
  • Fly ash Clay Brick

    These bricks are used less as they tend to pop out or get loose when they come in contact with water or moisture.Why is brick construction getting more popular nowadays?
  • Providing you with many options in colour, size, design and type, bricks provide you with an aesthetic approach
  • Unlike tiles or other materials, brick proves to be more durable and strong for a long period of time and is easy to maintain.
  • Release and absorb the moisture is one of the most important advantages of bricks, controlling the room temperature inside the infrastructure.
  • Provides you with a fireproof wall which is good for your safety.
  • If the bricks are kept properly then they can keep you away from sound pollution for sure.
  • Compared to other construction accessories, bricks can provide you with fewer maintenance charges which will help you save money and time.
  • Bricks are said to be the most durable and strong material ever made by a man, so you are assured with the best material which is strong and will provide you with a long-term service.
  • When compared to other materials bricks can exhibit above the natural thermal insulation. They can maintain and regulate interior temperatures due to their ability to absorb and slowly release heat. When compared to wood this can save more than 30 percent of energy.
  • Brick bears as an excellent wear resistance.

What are the common properties of bricks?

The main properties of bricks are thermal, mechanical, durable, and physical properties.

  • Physical properties of brick

Physical properties of brick include size, shape, colour, and density. Let’s check out this in detail:

(i) Size

In the same country, the size of brick used in construction varies from place to place and country to country. Paver blocks in India suggests that an ideal brick will have a standard size of 19×9×9 cm.

(ii) Shape

Bricks generally have well defined and sharp edges. Usually, an ideal brick has a rectangular shape. While making block mold the surface of bricks is regular and even. However special purpose bricks can be either cut or manufactured in many other shapes. Generally, these are the modifications of rectangular shapes.

(iii) Colour

For color mixer red is the most common colour of building bricks. Sometimes variations may occur from deep red to light red to purple and buff. Over burnt bricks are recognized by very dark shades and also yellow colour indicates under burning.

(iv) Density
Depending upon the used clay type and the method of brick moulding like stiff-mud, hard-pressed, soft-mud etc the density varies.

  • Mechanical properties of bricks

Flexure strength and comprehensive strength of bricks are included in this category.

(i) The comprehensive strength of brick

When bricks are used in load-bearing walls this is the most important property. The degree of burning and composition of clay is the determining factor of comprehensive strength. While considering load-bearing walls this is the most important properties of bricks.

(ii)  Flexure Strength.

We usually say that common building brick shall not be less than 10 kg/cm2 because bricks are used in situations where bending loads are possible in a building. Bricks hold sufficient strength against oblique loads.

  • Thermal properties of bricks

Other than strong and hard an ideal brick also provide an adequate insulation against cold, noise, and heat. Density and porosity are directly proportional to heat and sound conductivity of bricks. Since heavy and dense bricks conduct sound and heat at a greater rate they have a poor acoustic and thermal insulation qualities. All for this we suggests that bricks should be of enough strength, light-weight, and possess adequate insulation.

  • Durability of bricks

Durability decides the maximum time in which bricks remain unaltered and strong when used in construction. Automatic brick making is also quite popular nowadays because experience has been proved that properly manufactured bricks are the most durable form of the material of construction, that is they remain for hundreds of years. Durability mainly depends on efflorescence, absorption value, frost resistance.

(i) Absorption value.

Absorption value is completely related to the porosity of the brick. Actually, porosity is the ratio of the volume of pores to the volume of gross of the sample of the substance. Mainly this absorption characteristic of bricks affects their quality in many ways. They are:

  • When the porosity is high the material becomes less solid, hence the strength will be reduced.
  • Water-related defects like frost-action and efflorescence are the outcome of higher absorption.
  • This will also lead to deeper penetration of water which in turn will lead to dampness.

(ii) Frost Resistance.

Frost action is a common phenomenon in cold climate, this is because bricks are quite porous materials. So that it should be protected in areas having rain to minimize absorption.

(iii) Efflorescence.

In humid and hot climates contorting and a withering process of bricks is a common process. The surface of bricks get covered with grey or white patches of salts and these are present in the original brick clay. Salts get easily dissolved when rainwater penetrates into the bricks. Evaporation starts soon after the rain. Along with water the salt move out and form thin encrustations on the bricks surface. Sulphates of calcium, sodium, potassium, and magnesium are the common salts precipitated during efflorescence. This is the reason why great emphasis is laid while testing the chemical composition of the clay for the block paving of brick manufacturing.

Bricks are the only type of construction building that provides you to shape them according to your wants, you won’t have to buy more materials and waste the left over. So if you have plans to construct something you wish according to your design, I suggest you to try bricks as per your construction material with the strong brick moulds from JR Rubbers.
