Problems Cutting Paver Stone

Cracking

• While the most efficient way to cut pavers is with a hydraulic splitter or diamond-tipped blade and wet masonry saw, if you try to force the stone through the blade too quickly, or apply too much force on a shallow cut line, a paver can crack. It's advantageous to take your time and direct the stone steadily through the blade with consistent pressure, or score a cut line across each side of the paver before snapping it in half.

Jagged Edges

• Pavers are intended to sit flush against each other. Cutting them with a hand saw or hammer and chisel can create jagged edges, which not only prevents a tight fit with adjacent stones, but creates an eye sore. To prevent this, hold the chisel steady and aligned exactly with the cut line as you hit it with a hammer. Correct existing jagged lines by chiseling them down once the piece is snapped into two parts.

Uneven Lines

• The key to cutting pavers to fit exactly is to mark each stone with a cut line. Dry-lay them on the site according to your pattern; then snap or draw a chalk line over the excess portion. Plan to cut only the end pavers. Mark the bottom of each stone so you know where to place it once it's cut; and draw the cut line over the top, sides and bottom. Lay the saw or set the paver on a flat even surface to ensure the cut will be straight.

Harmful Dust

• Cutting pavers generates a significant amount of dust. In addition to the mess, this dust is harmful to your health. Always wear safety glasses and a face mask when cutting stone pavers, and ear plugs if using an electric saw. If you don't have access to a masonry wet saw, consider using a handheld chop saw with a hose attached to remove the dust as you work.
