Retaining Wall Finishing For the final row you have two options; you can use no capping modules or the Celtik Capping Modules.

For a finish without Capping Modules, use the same rectangular blocks you used to create the wall.

For a convex curve use the beveled blocks. Make sure to strike the extremities of the blocks at the back.

Simply spread concrete adhesive on the next to last row of the Celtik Wall and lay the last row of blocks.

The Celtik Capping Module

The Celtik Capping Module is sold separately, this Module offers a different type of finish, no anchor pins are necessary. Spread concrete adhesive on the next to last row of the Celtik Wall and lay Capping Modules over it.

To make a radius lay down the Capping Modules cut side by side...

...measure the distance between the two blocks, then split this measurement in two, and make a mark at the end of each block that will meet.

Cut with a concrete saw.

To make a 90 degree angle with the Celtik Capping Modules you again have two options; the first is to make a 45 degree cut with the concrete saw.

The second is to hammer down the right or left side of the Capping Modules, depending on the case, so that the two showing faces are similar.

Make sure to knock off the retaining lip lugs at the back of the block.
