Retaining Wall Installation

Concave Curves The Celtik Wall System facilitates the creation of curves. For a concave curve you don’t need to cut the blocks, just lay each block in position, alternating their lengths.

To create a convex curve you don’t need to cut the blocks, just strike the extremities of the block at the back and alternate their lengths.

The minimum radius of a convex curve is 36 inches or 90 cm.

Creating a 90 degree angle corner with retaining wall blocks

To create a 90 degree angle corner use the blocks that have grooves. They are included in the pallet.

Depending on if it’s a right or left corner, split the block along one of the two grooves. Proceed this way on the four faces of the block to get a good clean cut. Make sure to cut the textured side in last.

For your safety, we recommend you use safety glasses.

Strike the newly split surface with a hammer to attain the same finish as on the other blocks.

Insert the pin without blade in the round slot closest to the side.

We recommend you use concrete adhesive to glue the corner blocks together.

Lay the blocks down this way to get better stability and a natural look.
