What We Drill

Drilled shafts (also called drilled piers, caissons, or bored piles) are the workhorse deep foundation in Texas. We excavate a cylindrical hole to design depth, set the rebar cage, and place concrete — creating a high-capacity foundation element that transfers structural loads through weak surface soils down to competent bearing strata.

Straight shaftsFor bridges, buildings, signs, sound walls, and equipment foundations — drilled to bear in competent material.
Bell-bottom piersUnderreamed footings that spread the load — a proven answer to the expansive clays common across East Texas and DFW.
Rock socketsShafts socketed into limestone or shale where design loads demand it.
Cased & slurry drillingTemporary casing or slurry methods for wet or caving ground, common near creeks and bottomland sites.

Why East Texas Contractors Call Us

We're headquartered in Henderson County — minutes from Athens and Tyler, about an hour from Dallas. When a statewide drilling outfit has to mobilize a rig from Houston, you pay for every mile. Our rigs are already here, which means lower mobilization, quicker scheduling, and a crew that knows the difference between the sands of Van Zandt County and the black clay of Ellis County. We also self-perform auger cast piles, micropiles, and earth retention, so one sub can cover the whole deep-foundation scope.

Frequently Asked Questions

How deep do drilled piers need to be in East Texas?

It depends on the structure and the soil. In the expansive clays common around Athens, Tyler, and Dallas, piers typically extend below the active moisture zone — often 8 to 20 feet for light structures, and much deeper where a geotechnical report calls for bearing in a specific stratum. Bridge and heavy structural shafts are designed from boring logs and can run 30 to 60+ feet. Send us your geotech report and we'll price to it.

What diameter shafts can you drill?

We handle the full common range — from 12-inch piers for light commercial and residential work up through large-diameter shafts for bridges, towers, and heavy structures. Diameter, depth, and reinforcement all come from your project's structural design; our estimate follows your plans and specs.

Do you work as a subcontractor to general contractors?

Yes — that's most of our work. We sub to GCs, TxDOT primes, electrical contractors, and builders across East Texas and DFW. We can provide certificates of insurance, and we're a registered TxDOT vendor.
