Foundation Settlement Repair Seguin, TX.
Homes along the Guadalupe River corridor sit on deep, thirsty clay that moves with every drought-to-flood swing. Here's how GroundLock measures that movement in Seguin and lifts your foundation back toward level.
If your doors have started catching on their frames and a diagonal crack has crept up from a window corner, the ground under your Seguin home is very likely the culprit. This stretch of Guadalupe County sits on thick alluvial and lacustrine clay laid down over centuries of Guadalupe River flooding, not the thin, pebbly fill you'd find on the limestone terrain west of here, but a deep column of low-permeability clay that swells when it rains and consolidates hard when it dries.
That behavior is measurable, and measuring it is where any honest repair starts. GroundLock treats settlement in Seguin as an engineering problem first: map exactly how far the structure has moved, then design the pier plan around that data rather than a rule of thumb. The result is a written scope you can hold your contractor to, and a lift that puts the slab back where it belongs.
Why Seguin's Guadalupe River clay settles the way it does
The soils along this corridor are high-plasticity clays, with a plasticity index that commonly lands somewhere between 35 and 60 in this kind of deposit. Plasticity is just a measure of how much a clay shrinks and swells for a given change in moisture, and these soils shrink and swell a lot. The active zone, the depth of soil that actually reacts to seasonal wet and dry cycles, can reach eight feet or more here. So the ground influencing your foundation isn't a thin surface skin; it's a substantial mass cycling between states.
When an extended dry spell pulls water out of that column, the clay consolidates and the foundation drops, rarely evenly, which is what produces the racked door frames and out-of-plumb interior walls. When the rains return, moisture recharges some zones faster than the soil can equilibrate, and those areas can heave. The push and pull across a single slab is what makes the cracking look erratic.
This is also why pier depth matters so much in Seguin. Concrete pressed piers are cured on site and often terminate at relatively shallow depths, sometimes still inside the moving clay that caused the trouble. GroundLock's galvanized steel piers are driven hydraulically through the active zone and into competent load-bearing strata below, where seasonal moisture swings no longer change the soil's volume in any meaningful way.
How a Seguin settlement repair actually unfolds
Free elevation survey to ±0.01 in.
We shoot a grid of measurement points across the accessible interior with leveling equipment calibrated to 1/64 inch, producing a contour map of exactly where and how far the foundation has settled.
Engineer-backed written plan
That survey drives a written proposal specifying pier count, pier locations, and the target lift at each point, no guesswork, and something a third-party engineer can review.
Steel piers driven to refusal
Each galvanized pier is advanced under the weight of the house itself until it reaches firm strata and the hydraulic pressure hits the design threshold, which doubles as a proof test of that pier's capacity.
Controlled lift and closeout
Piers are loaded together to raise the structure back toward level; larger jobs are closed out with a stamped report, and most homes stay occupied the entire time.
Keep water from undoing the repair
Grade should fall at least six inches over the first ten feet away from the foundation. Flat or negative drainage lets water pond against the beam and restarts the same moisture cycling that caused the settlement.
Keep sprinkler heads and soaker lines back 18 to 24 inches from the perimeter, too, an artificial wet ring right at the edge amplifies differential movement in clay this active. Ask us about drainage or erosion control if the site around your home needs it.
