Step 5: Cut Blocks as Needed
Warning
Always wear eye and hearing protection when splitting or cutting concrete blocks. At the ends of alternate courses, you may need to cut or split partial blocks to complete the ends of the row. Splitting can be done by slightly scoring the top of a block with a wide masonry chisel and hammer, gradually deepening the score until the block cleaves along the scored line. For a cleaner cut, use a circular saw with diamond blade to cut the block. 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.
