Helical piles in Carrollton, Texas

Carrollton is in the Dallas area, on the Blackland Prairie side of the I-35 corridor, where the Soil Science Society of America says the state soil, Houston Black, is a shrink-swell clay that can crack several feet deep in a dry summer. Those wet-dry cycles lift and drop slabs, which is why foundation repair is a steady business from Dallas to San Antonio.

Helical piers bypass the active clay layer and bear on firmer soil below it. Frost is a minor factor across most of Texas; Houston's local table lists a 6-inch frost line, and the controlling design issue is usually the depth of the active clay zone, not frost.

Costs and what to ask

HomeGuide reports typical installed prices of roughly $2,000 to $4,000 per pier nationwide. Texas jobs can land anywhere in that range depending on how deep the stable layer is, how many piers the slab needs, and site access. Read our helical pier cost guide for what a quote should include.

Questions to put to any installer:

• Who is the engineer of record for active clay, and what loads were assumed?
• What final torque and depth will each pile reach, and will those readings be documented?
• Is the shaft hot-dip galvanized, and is that enough in clay soil?
• Does the quote include permit fees from the City of Carrollton, and how long does the warranty run in writing?
