Rock Face & Flat Top Block

Are you building a wall or structure, but you don’t want to go through the hassle of using bricks and mortar?

Then, you should consider investing in Rock Face & Flat Top Blocks. These are a type of Interlocking Concrete Block. They are a unique form of pre-cast concrete blocks that are designed to hold together by using pre-measured studs and recesses.​

Rock Face & Flat Top Blocks are slightly different to Standard Blocks, as they do not have nipples on top of them. Also, Rock Face & Flat Top Blocks have a rocky exterior on one face of the block.

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.

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
  • for creating a barricade at open rail lines
  • for preventing unauthorised vehicles and pedestrians from trespassing on dangerous land.
