Foundation repair McQueeney, TX.

The soil that makes McQueeney such a green, riverside place to live is the same soil that cracks its foundations. Thousands of Guadalupe River flood cycles left behind deep terrace clays, and those clays are unusually good at holding water, swelling in a wet winter, drying and pulling back in a hard Central Texas summer. A slab poured on ground that keeps changing volume eventually starts to move with it.

What that looks like inside a house is familiar to a lot of people out here: a door that suddenly won't latch, a hairline crack climbing from a window corner, a floor that feels like it tilts toward one room. GroundLock works on these terrace-clay foundations specifically, and the fix isn't guesswork, it starts with measuring exactly how far the foundation has moved, then transferring the structure's weight down to strata that don't rise and fall with the weather.

Signs your McQueeney foundation is moving

On terrace clay, distress usually shows up in a predictable order. If you're seeing several of these together, it's worth a measured look:

• Diagonal cracks running out from the upper corners of interior door and window frames, often the very first sign on a slab.
• Doors that bind, drag, or leave an uneven gap at the top, and windows that stick where they used to slide.
• Floors that feel sloped or bouncy in one part of the house while the rest sits flat.
• Separation where a brick or stone veneer meets a window, or stair-step cracking in exterior masonry.
• Gaps opening between crown molding, cabinets, or countertops and the wall behind them.
• One side of the house clearly drier than the other, common where a large oak or shrub bed pulls moisture from the clay on that side.

Why the ground near the lake behaves this way

McQueeney's terrace deposits are high-plasticity clays, rich in smectite-group minerals that bond with water and physically expand their structure as moisture rises. That's the whole story behind the seasonal cracking: when the clay matrix takes on water it lifts against the slab, engineers call it heave, and when it dries in summer it contracts and lets the foundation settle. Repeat that a few dozen times and the movement stops being uniform. One corner rides high while another drops, and the difference is what tears at door frames and floors.

The number that matters most here is the depth of the active zone, how deep seasonal moisture swings actually change the soil's volume. Unlike the thin soils over Edwards limestone to the west, these river-terrace clays run deep, so their active zone runs deeper too. That's why grading and gutters alone, while genuinely helpful, rarely stabilize a foundation that has already lost bearing. You can't drain your way out of movement that's happening well below the surface.

Managing water still matters, it slows the cycling and protects a repair. Keeping surface water shedding away from the perimeter (a fall of about six inches over the first ten feet) and keeping deep-rooted trees set back from the slab both help. If drainage or slope is part of your problem, our drainage and erosion-control work addresses the water directly rather than just chasing the cracks it leaves behind.

How a GroundLock repair goes here

What the piers actually solve

Galvanized steel piers work because they stop relying on the problem soil. Instead of asking the shrink-swell clay to hold the house steady, the load is carried straight down to strata below the depth where moisture swings have any influence. That's the difference between resetting the clock and stopping it. The galvanizing is there for the long haul. These piers stay in the ground and in service for the life of the structure, which is why the warranty behind them is transferable to the next owner.

Cost tracks the work, not a menu. Most McQueeney steel-pier projects land in the range of $4,500 to $14,000, driven mainly by pier count, site access, and whether drainage repair is part of the scope. The free elevation survey is what turns that range into a real number before anyone commits, and financing is available if it helps. Nearly every job is done while you stay in the home, crews work from exterior access points and clean up before they leave. If you want the full picture of the process, our foundation repair overview walks through it end to end.
