Content: Making a series of cuts at gradually deeper blade depths is usually the best way to cut blocks. Advertisement
If the wall must make a sharp angle, you can cut the blocks at a 45-degree angle at the point where the wall changes direction. The cut faces of the miter can be joined together with exterior-grade concrete adhesive. Step 6: Mark, Cut and Install Caps
The top course is made with special cap blocks that are usually thinner than the wall blocks. Install the caps so the fronts overhang the underlying blocks by about 1 inch. Use exterior-grade concrete adhesive to glue them in place. For curved walls, the cap blocks will need to be trimmed along the sides so they can conform to the radius of the wall. Step 7: Install Landscape Fabric
Although this step is sometimes omitted, it is a good idea to line the back of the trench behind the retaining wall with landscape fabric.
