Helical piles in San Antonio, Texas

Clay that shrinks and swells with the seasons is the main reason foundation repair is a steady business across Texas. Helical piers answer it by bypassing the active layer and bearing on firmer soil, and since they are screwed in with hydraulic equipment, they work in tight backyards and under existing homes where a drilled concrete pier is harder to place. Frost is a minor factor, so the state soil guide points to the depth of the active clay zone as the controlling design issue.

Typical Texas uses include underpinning slab homes that have settled, foundations for room additions tied into an existing slab, deck and patio cover footings, and ground-mount solar on ranch land. Most Texas cities require a permit for foundation repair and new structures, though rules vary, so ask the City of San Antonio what applies.

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. Texas jobs can land anywhere in that range depending on the stable layer, the pier count and access. See our helical pier cost guide for the main cost drivers. Questions to ask:

• Do you install helical piers, and to what depth below the active clay zone?
• Will an engineer set the required torque for the design load?
• Will you provide torque logs?
