interlock brick

Types of interlock bricks

Interlock bricks are unique bricks that can create a stable and interlocking surface without the use of mortar joints. They can be integrated into traditional and modern architectural designs. The use of interlock bricks can be traced back to the ancient Roman period, and they have made a significant comeback in the machinery industry due to their many advantages.

• Cement interlock bricks

  Cement interlock bricks are often used in the construction of residential and public buildings. They are typically three to five feet long, two to three feet wide, and up to one foot high. Their shapes vary depending on the manufacturer's specifications, but they have unique patterns that allow them to fit together tightly. Cement interlock bricks are made by mixing cement, sand, and water, then pouring the mixture into molds where it will harden before being removed from the mold. Unlike traditional cement blocks, which require mortar between each block for stability, cement interlock bricks lock into place. Therefore, they are easier to install than standard cement blocks, making them an attractive option for DIYers.

• Plastic interlock bricks

  Plastic interlock bricks are an eco-friendly solution for creating stable surfaces. They are made from recycled plastic, which helps reduce plastic waste in landfills and oceans. Plastic interlock bricks come in various colors and designs, giving users the freedom to make personalized and aesthetically pleasing places. Additionally, plastic interlock bricks are lightweight and simple to install, making them the ideal choice for people who aren't particularly skilled or who want to complete a project quickly.

• Soil interlock bricks

  Soil interlock bricks are made from stabilized compressed earth blocks (CEBs). Raw materials extracted locally are used to make these bricks, which makes them a good, sustainable choice that supports the neighborhood economy. Soil interlock bricks are produced by mixing soil, cement, and water, which are then compressed to form the bricks. They are a cost-effective option for constructing pavements and walls.

Specifications and Maintenance of Interlock Bricks

Specifications

• Sizes and Shapes

  Interlock bricks typically come in standard rectangular forms, such as 225x112.5x75mm, 275x215x115mm, and other similar dimensions. The variation of shapes may include larger blocks for building cores or thinner, denser variants for facade construction.

• Color and Texture

  Interlock bricks are available in several hues, including the traditional red or brown, which is formed through iron oxide, and other formulations that utilize differing raw materials. Surface options comprise smooth, rough, embossed, frosted, or any format that provides sufficient grip for pedestrian traffic.

• Mechanical Properties

  The mechanical features of interlock bricks include compressive strength and durability. When creating interlocking bricks, it is essential to choose the appropriate raw materials and firing temperature to ensure their long life spans and ability to support large weights without breaking.

  For example, the compressive strength of interlock bricks should typically be more than 7.5 MPa, equivalent to high-strength bricks, while the durability should be equivalent to a minimum of 100 years.

• Installation Method

  The interlock bricks are placed without mortar, and the compressive strength depends on the weight of the traffic.

Maintenance

In many instances, no maintenance is necessary, but if after some years, the interlocking paver stones appear hazy or dirty, the following is the cleaning procedure:

• User can external alkaline based cleaner, which is sodium hydroxide, to remove stains.
• For oil stains, use a degreaser and industrial acid-based cleaner.
• If fungi or algae are present, make use of bleach or sodium hypochlorite.
• For moss, make use of salt or sodium chloride.
• Before cleaning, the entire area to be cleaned should be dampened with water.
• While using chemicals, the instruction manual should be carefully followed.
• After cleaning, it is essential to seal the blocks, and this will stop sand loss from the joints.

It is optional, but it is preferable to apply sand at the joints after cleaning, which is silica sand, and re-compacting the joints with vibrating plate compactor. Some polymers should be used in sand to protect against growth and have better wear resistance.

The sealing of the blocks will help to prevent efflorescent material from being deposited on the surface. It will also aid in surface treatment and make maintenance easier. If the surface of interlocking bricks is not damaged, any solvent-based or water-based sealants should be applied.
