Splitting and Cutting Patio Block

To Split a Block

Use a hammer and chisel to score the block on all sides. Pound the chisel on the score line until the block splits.

To Cut a Block

Use a circular saw with a masonry blade.

To Cut a 90-Degree Mitered Corner

Use a circular saw with a masonry blade. Cut a 45-degree angle on two blocks. Glue the cut sides together with exterior-grade concrete adhesive so the two faces form the finished outside corner.


Always wear eye protection and work gloves when splitting block. If you use a power saw to cut block, you'll also need hearing protection and a dust mask. Follow the saw and blade manufacturer's instructions for use and safety.
