Keystone Quarry, Inc. operates a state-of-the-art crushing system that can produce over 1.5 million tons of aggregate (see Products) over a twelve month period. It is considered one of the most advanced rock crushing systems found anywhere in the United States. Fully computerized, production quantities of various materials can be changed by the flip of a switch with virtually no down time. And, as always, Keystone has Certified Aggregate Technicians on site conducting daily testing to ensure that all materials meet PA state certification requirements.

Keystone Quarry is located within one mile of the intersection of Interstates 380 and 81 (see Directions). Keystone is open six days a week during the construction season and offers a complete selection of materials at competitive prices. If you cannot pick up your order, Keystone can arrange delivery for a very reasonable cost.
