Concrete Blocks

Are you looking for a quick, easy and cost-effective solution for building walls and structures?

Then, consider investing in Interlocking Concrete Blocks. They 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, without the use of mortar or any fixing materials like grout. Instead, the cementitious blocks simply snap together with each other.

Interlocking Concrete Blocks are easy to install and can be organised in many different shapes and patterns. They are strong, durable and designed to last for years to come, so they are suitable for permanent structures, such as retaining walls.

These dense concrete blocks can also be used for temporary works. For example, for creating barriers for music festivals or open rail lines, or for preventing unauthorised vehicles and pedestrians from trespassing on dangerous land.

Interlocking Concrete Blocks come in various types, including:

  • Standard Blocks
  • Flat Top Standard Blocks
  • Rock Face Blocks
  • Rock Face & Flat Top Blocks
  • Concrete Lego Blocks

Why should I use Interlocking Concrete Blocks?

Interlocking Concrete Blocks can be used as a temporary or permanent feature, which is why many home remodelling projects employ interlocking blocks as a building material. The concrete blocks are sturdy, versatile and offer excellent support and stability.

Interlocking Concrete Blocks are ideal for temporary works- when you have finished using them, they can be taken apart and reused for another purpose- which makes them a unique, eco-friendly building material.

These weatherproof concrete blocks have excellent freeze-thaw resistance, so they won’t be damaged in extreme weather conditions like heavy snow and torrential rain.

The thickness, strength and composition of Interlocking Concrete Blocks also give them excellent fire resistance properties, which help to stop a fire from spreading.

What is the difference between cinder blocks and Concrete Blocks?

A cinder block is a lightweight building material which is made of cement and coal ash. They usually have hollow cores in the middle.

There are a few differences between cinder blocks and concrete blocks, such as:

  • Cinder blocks are more expensive than concrete blocks.
  • Cinder blocks are lighter than concrete blocks.
  • Cinder blocks have a hollow rectangle structure, whereas concrete blocks have a flattened structure.
  • Concrete blocks are much stronger than cinder blocks- so they tend to be used for larger and more important construction projects.
  • Cinder blocks have a lot less tensile strength than concrete blocks do.
  • Cinder blocks require more repairs than concrete blocks do.

How do you store Concrete Blocks?

  • Store the concrete blocks in a cool, dry place. Make sure they are protected from severe weather conditions, to help maintain their quality.
  • Make sure the ground of the storage area is perfectly flat.
  • Keep the concrete blocks close to the site of work, to make transportation easier.
  • Do not stack the concrete blocks higher than two to three blocks at a time.

Do you need a forklift to lift Concrete Blocks?

Yes, generally, you may need a forklift to move concrete blocks, but they are easy to lift and manoeuvre. The concrete blocks are designed for easy lifting, as the block fits nicely into the lifting loop. For easy stacking, ensure the concrete blocks are placed on a flat area.

Forklift hire is generally affordable, and you won’t need to rent it out for long, as Interlocking Concrete Blocks require less manpower and less time for building.

How do you stay safe when handling or building with Concrete Blocks?

  • Don’t load out blocks by hand- use a machine or handling equipment, like a forklift.
  • If you need to handle lighter concrete blocks, handle them close to the body when lifting into position.
  • Do not stand on the concrete blocks.
  • When operating a forklift, wear a hard hat, safety shoes and a high-visibility jacket.
  • Inspect the forklift for defects before operating and watch out for passers-by in your blind spots.
  • If you need to mechanically cut any concrete blocks, make sure you wear appropriate eye protection.
