What is an Interlocking Concrete Block?

Which grade of concrete is the most waterproof?

Interlocking Concrete Blocks are a unique form of pre-cast concrete blocks that are designed to hold together by using pre-measured studs and recesses.​ These concrete blocks are built with unique profiles and features, which allow them to fit perfectly into each other.

What is a flat top interlocking concrete block?

A flat top interlocking concrete block is the block that would be placed at the top of a structure that uses Interlocking Concrete Blocks. As the name suggests, the difference is that it has a flat top, as opposed to the studs that every other block would have at the top.

What this means is that once this block is placed, it can not be stacked upon, as it will be unsafe and unsecured. This is why this block is always placed at the top of the structure.

That being said, the flat top interlocking concrete block does have recesses at its bottom, which allow for blocks beneath it to connect to it securely.

Flat top blocks serves as the final piece to your Interlocking Concrete Block-made structure. It can also be removed with heavy lifting equipment. Although you don’t have to have the block on top of every structure, it can serve to make the wall more presentable, which is crucial for structures that are in a professional environment.

So why do you need Interlocking Concrete Blocks? As simple as they may seem, they provide multiple benefits for anyone undertaking builds. Their viability makes them applicable in a variety of scenarios.

Interlocking Concrete Blocks do not require binding materials

Interlocking Concrete Blocks require less manpower

Because of the sizes available, and the requirement of lifting equipment in order to safely and correctly place the blocks, Interlocking Concrete Blocks require less manpower.

Interlocking Concrete Blocks come in many sizes

The variety of sizes available for Interlocking Concrete Blocks makes them versatile, whether it is a small retaining wall, a large one, and so much more, you are covered.

Interlocking Concrete Blocks can be reused

Interlocking Concrete Blocks can be used for temporary builds, this means that when the use of the temporary build has been completed, the blocks can be moved, and used again. That being said, we would never recommend reusing a block that has received extensive damage.

Some uses of Interlocking Concrete Blocks include…

  • Material Storage bays
  • Blast walls
  • Salt stores
  • Crash protection
  • Push walls
  • Security barriers
  • Segregation bays, i.e. recycling centres
  • Retaining walls
  • Industrial buildings
  • Fire breaks
  • Counterweights
  • Roadblocks

Interlocking Concrete Blocks can be stacked

When it comes to height, Our standard-sized blocks are 60 cm in height, with 5 stacked together this would equate to 300 cm, which is exactly 9 feet (2.74 m) & 10.11 inches (ca. 26 cm) high. This means that a flat-top concrete block can be placed at a maximum of 9 feet (2.74 m) high.

Keep in mind that we do have a variety of sizes that we offer, so the maximum height of your structure will be directly affected by the size of the block that you choose.

Interlocking Concrete Blocks are durable

As they are made from concrete, Interlocking Concrete Blocks have a natural resilience due to their durability. This is especially true if they are prepared correctly and allowed to cure before usage.

Their durability allows them to handle most impacts effectively, and are also weatherproof, which can be further reinforced by sealant if you decide to apply it.

Ultimately, these benefits can help you save money in the long-term by using fewer materials than you would with bricks and mortar. Their application requires less manpower, and the durable, long-lasting nature of the blocks means the likelihood of repair being required is extremely low.

Is it better to use bricks or Interlocking Concrete Blocks?

This depends on the structure being created. Although Interlocking Concrete Blocks have numerous benefits, it can’t be used for every building project. The same goes for bricks, they are useful, but have nowhere near the amount of benefits or viability that Interlocking Concrete Blocks have.
