Helical Pier Installation for DFW Homes
Helical piers — also called screw piles or helical anchors — are steel shafts with spiral bearing plates that are mechanically screwed into the ground until they reach stable, load-bearing soil. They're particularly valuable in the DFW market for situations where traditional pressed concrete piers can't be used: tight access areas, new construction, home additions, and properties where soil disturbance must be minimized.
Cracks in your walls? Sticking doors? Don't wait — foundation problems get worse.
What is Helical Pier Installation?
A helical pier is essentially a large steel screw driven deep into the earth using a hydraulic torque motor. The helical plates — like the threads on a screw — advance the pier through unstable surface soils and into deeper, competent load-bearing strata. Once installed, the pier is attached to a steel bracket that connects directly to the foundation. Helical piers work in compression (supporting downward loads) and can also resist tension and lateral forces, making them more versatile than pressed concrete piers in certain applications. In the DFW market, helical piers are frequently specified by structural engineers for challenging conditions: variable soil profiles, high groundwater, or locations where heavy equipment cannot access the work area.
Signs You May Need Helical Pier Installation
- Foundation movement in an addition or recently built structure
- New construction in an area with known poor soil conditions
- Settlement in a section of the home where access is too tight for standard equipment
- Structural engineer specification calling for helical piers on repair or new construction
- Property near drainage features, ponds, or areas with variable water table
How We Do It
Soil & Load Assessment
We review soil boring data or conduct a field assessment to determine the depth to competent bearing strata and calculate the load each pier must carry.
Engineer Specification
A structural engineer specifies the pier diameter, helix configuration, and target installation torque based on soil conditions and structural loads.
Mechanical Installation
A hydraulic torque motor is used to rotate the helical shaft into the ground, monitoring torque readings to confirm when the piers reach target bearing capacity.
Bracket Attachment & Lift
Steel load-transfer brackets are welded or bolted to each pier and connected to the foundation. Hydraulic jacks then transfer the structural load to the piers.
Why North Texas Clay Soil Makes This Critical
North Texas's geological profile includes loose, expansive clay in the upper 10–20 feet transitioning to harder shale and limestone at depth. Helical piers are particularly well-suited to this profile because they can pass through the unstable clay zone and engage the deeper rock-like layers, providing a stable bearing point that isn't affected by surface soil moisture changes. In areas near Lewisville Lake, Lake Ray Hubbard, and along creek corridors, where groundwater levels fluctuate significantly, helical piers offer installation advantages over pressed piers that rely on soil resistance alone.
