How to Build a Driveway Apron

Wearing safety glasses and hearing protection, use a concrete saw to score a shallow cut along your chalk line. Then attach a garden hose to the fitting on the saw and turn on a low flow of water to cool the blade and reduce dust as you cut all the way through the slab. Dip the blade into the line as you go rather than trying to force the saw forward. Gauge your cutting depth to avoid hitting the aggregate base.
