Cut Patio Block

When building a retaining wall, patio or walkway, you'll most likely need to cut the concrete blocks or pavers to fit your project. Use these tips to make cuts for your hardscape creation.

How to Cut Patio Blocks and Pavers

Cutting a Paving Stone with a Circular Saw and Concrete Blade.

Hammer and Chisel

You can split block or pavers with a drilling hammer and a mason's chisel. This method is useful if you just have a few cuts to make. Use the hammer and chisel to score or cut a groove into the block or paver on all sides. Strike the chisel on the score line until the material splits.

Power Saw and Concrete Blade

For a larger project or more accurate cuts, a circular saw with a concrete blade is a good option. Mark the cut and clamp the stone or paver to a stable work surface. Cut the block, allowing the saw and blade to do most of the work — don't apply too much force. Back the saw out after about 30 seconds to avoid overheating. Depending on the thickness of the material, you may need to make several passes, lowering the blade with each pass. You may also need to turn the block to cut it on all sides. Follow the saw manufacturer's instructions for blowing dust out of the saw. Accumulated concrete dust can cause motor wear.

A concrete saw or a wet saw can be a helpful alternative if you need to make many cuts. Ensure the saw and the blade are both appropriate for the material you're cutting.

Good to Know

To create a 90-degree mitered corner, 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 corner.

Caution

Wear eye protection and work gloves when splitting or cutting block. If you use a power saw, you also need hearing protection and a dust mask. Follow the saw and blade manufacturer's instructions for use and safety.
