Shermans Dale

Helical piles in Shermans Dale, Pennsylvania

Pennsylvania has two very different trouble spots for foundations. In the east and central valleys, limestone and dolomite bedrock produce sinkholes, and the Pennsylvania Geological Survey has inventoried karst features in counties such as Lehigh since 1985. In the southwest, steep hills and weak claystones make the Pittsburgh region the most landslide-prone area in the state.

Helical piles give engineers a way to reach competent material over voids, and each pile can be tested as it is installed. An engineer may request a geotechnical review on karst sites, and DCNR's karst inventories are a useful starting point. Frost depth is set by each municipality, commonly between about 30 and 42 inches, so confirm your township's value.

Costs and what to ask

HomeGuide reports that helical piers cost about $2,000 to $4,000 each installed nationally, with about $3,000 typical. Pennsylvania prices shift with depth to bearing, slope access and how many piers the load requires. See our helical pier cost guide for the main cost drivers. Questions to ask:

• Does this lot sit in a karst area that calls for a geotechnical review?
• How deep will piles go, and what torque is the engineer targeting?
• Will you provide torque logs for each pile?
• What galvanizing is used, and who pulls the permit and covers the warranty?
