Austin's older neighborhoods like Hyde Park, Clarksville, and Travis Heights sit on black clay that swells in spring rains and shrinks during summer droughts, pushing and pulling slab foundations. Pier installation reaches stable strata below the active zone, typically 8 to 15 feet down depending on the lot's proximity to Lady Bird Lake or Barton Creek. We use either reinforced concrete or galvanized steel piers driven or screwed to refusal, then bracketed to the beam or slab edge. In East Austin and Mueller infill areas, shallow fill over native clay often requires longer piers or a combination system to avoid re-settlement after the next wet winter.
Homeowners in Westlake and Barton Hills frequently request pier work when stair-step cracks appear along limestone outcrops or when pools near Zilker Park show seasonal tilting. The process begins with a level survey and hand-auger borings to map soil layers before any equipment arrives. We avoid over-driving piers near the University of Texas campus or the Capitol grounds where vibration limits apply. Once load-tested, each pier is locked off with a concrete cap or steel saddle so the slab can be lifted in small increments without cracking interior finishes.
Round Rock and Pflugerville new-construction slabs sometimes need piers when builders cut corners on site grading near the Edwards Aquifer recharge zone. We coordinate with Travis County inspectors on setback distances from septic fields and drainage easements. Mild winters let us work year-round, but we schedule around the spring wildflower season in Zilker and the heavy May rains that saturate South Congress yards. Every job includes a written load-transfer plan so owners know exactly which walls receive support before we mobilize.
Technician insight
In Austin the thing that catches most people out with Foundation Pier Installation is underestimating how fast the clay dries out after a spring rain once you start excavating near Zilker or Barton Hills; one dry week and the hole walls collapse, forcing you to switch to a cased helical instead of the planned concrete pier.
Hyde Park Slab Settlement
A 1940s bungalow near 45th Street showed widening cracks after two wet winters. Borings revealed 11 feet of active clay over limestone. We installed eight steel push piers along the east beam, load-tested each to 12 tons, and lifted the low corner 1.25 inches. The slab has remained stable through the following summer drought.
Foundation Pier Installation Services We Offer
✓Concrete Pier Installation
Cast-in-place or precast concrete piers driven to refusal for older Hyde Park and Clarksville slabs experiencing seasonal heave.
✓Helical Pier Systems
Screw-style helical piers installed with low vibration near Lady Bird Lake homes where torque monitoring confirms bearing capacity.
✓Steel Push Pier Installation
Galvanized steel push piers used in tight East Austin lots where access limits larger equipment and soil is highly expansive.
✓Foundation Pier Load Testing
On-site hydraulic testing of each pier to verify it meets the engineered load before final bracket attachment.
✓Slab Edge Pier Placement
Targeted piers along perimeter beams in Barton Hills homes to correct differential settlement from hillside drainage.

How it works
- 1
Site Evaluation
Level survey and soil borings at multiple points around the Austin home to map clay depth and locate utilities.
- 2
Pier Layout
Mark exact pier locations along beams or slab edges, accounting for setbacks from Barton Springs Pool drainage or Mueller greenbelts.
- 3
Installation
Drive or torque piers to refusal, then attach adjustable brackets and perform incremental lifting under engineer guidance.
- 4
Final Lock-Off
Secure piers, backfill holes, and document final elevations for Travis County records.
Pricing
Upfront written quotes after on-site inspection; total cost depends on pier count, depth, and access constraints in Travis County neighborhoods.
