Expert slab-on-grade foundation repair for Abilene homes. We fix cracking, heaving, and settlement caused by Texas clay soil — using bell bottom piers, steel piers, and foam injection. Free inspections with lifetime warranties.
Horizontal, vertical, or stair-step cracks in your concrete slab caused by soil movement, settling, or hydrostatic pressure beneath the foundation.
Upward movement of the concrete slab caused by expanding clay soil absorbing moisture, pushing sections of your foundation higher than designed.
Downward movement as soil beneath the slab compresses, dries out, or washes away — common during Abilene's drought cycles.
Concrete piers with a bell-shaped base poured directly into Abilene's clay soil. The wider bottom distributes weight across more soil area — ideal for slab foundations on expansive clay.
Galvanized steel piers driven through unstable soil to bedrock or load-bearing strata. Best for severe settlement where the slab needs to be lifted back to level.
High-density polyurethane foam injected beneath the slab to fill voids and lift settled concrete. Minimally invasive with same-day results.

A slab-on-grade foundation is a single piece of concrete resting directly on soil, which makes it entirely dependent on that soil staying put. Under most Abilene homes it does not. Expansive clay swells and shrinks through the year, and the slab has to accommodate whatever shape the ground beneath it takes.
Because concrete is strong in compression and weak in tension, a slab tolerates being pushed up far better than being left unsupported. The classic Abilene failure is a corner or edge that loses support as clay shrinks back in summer, leaving that section spanning a void until it cracks. Interior cracks that run diagonally from a door frame are usually the same thing showing up in the framing above.
Two things accelerate it. A plumbing leak under the slab keeps one zone permanently wet while the rest of the lot dries, creating exactly the imbalance that does damage. Large trees close to the foundation do the reverse, drawing moisture out and causing localised shrinkage. Both are worth ruling out before anyone quotes piers.
| Option | Typical cost | Lifespan / duration | Best for | Notes |
|---|---|---|---|---|
| Perimeter piers | $350–$800 per pier installed | Lifetime transferable warranty | Settlement at the edges of the slab | Exterior work, so no flooring is disturbed. The most common Abilene slab repair. |
| Interior piers | Same per pier, higher labor | Lifetime transferable warranty | Settlement under a load-bearing interior wall | Requires ~6 in. holes through the slab, patched afterward. Tile or hardwood in the path needs repair. |
| Foam void fill | Lower than piering | Permanent if erosion is stopped | Voids under a slab that has not structurally settled | Fills gaps rather than carrying load. Does not substitute for piers where the slab has dropped. |
| Full slab replacement | Several times any repair above | New slab | Severe structural failure only | Requires vacating the house for weeks. Rare on Abilene residential slabs — stabilization is nearly always the answer. |
Almost always the soil, not the concrete. Abilene sits on expansive clay that swells when it takes on water and shrinks when it dries, and West Texas gives it extremes of both — months of drought followed by several inches of rain in an afternoon. That cycle lifts and drops different parts of your slab by different amounts, and concrete, which is strong in compression and weak in tension, cracks where it is pulled. Plumbing leaks under the slab accelerate it by keeping one area permanently wet. Large trees close to the foundation do the opposite, drawing moisture out and causing localized shrinkage. Poor drainage that dumps roof runoff against one wall creates the same imbalance. Abilene Foundation Repair looks for the moisture cause before quoting piers, because stabilizing a slab without fixing the drainage or leak that destabilized it usually means the homeowner is back within a few years.
Replacement is almost never the answer for a residential slab in Abilene. Tearing out and repouring a slab under an occupied house costs several times what stabilization costs and requires moving out for weeks. The standard fix is to support the slab from below with piers at the settled sections, lifting it back toward level and holding it there, then patch the cracks themselves. Crack repair alone — epoxy or polyurethane injection with no piers — is only appropriate when the slab has stopped moving and the crack is cosmetic. Injecting a crack on a slab that is still settling simply produces a new crack a few feet away. Abilene Foundation Repair will tell you which situation you are in based on crack width, pattern and elevation readings taken across the floor. Full replacement gets recommended only for severe structural failure, which in twenty years of Abilene homes is rare.
Most slab repairs in Abilene are finished in one to three days. A simple installation of six to eight piers along one settled side is often a single day. More complex jobs involving twenty or more piers, or lifting a slab that has dropped significantly, can run up to a week. Your home stays livable throughout — crews work outside and beneath, plumbing and power stay on, and the site is cleaned at the end of each day. The lift itself is deliberately slow: raising a slab too fast cracks tile, drywall and plumbing, so we bring it up in stages and monitor as we go, sometimes stopping short of dead level on purpose because forcing the last quarter inch would do more harm than the remaining slope. Abilene Foundation Repair explains that target elevation before starting so you know what "finished" will look like.
Interior pier installation requires drilling holes roughly six inches in diameter through the slab at each pier location, and those are patched with concrete once the pier is set. Flooring directly over a hole is affected: tile in that spot has to come up and be replaced, and hardwood needs a patch. Carpet and vinyl are usually liftable and re-layable with no visible trace. Exterior piers touch no flooring at all, which is one reason we place piers outside wherever the load path allows. There is a second effect worth expecting — as the slab lifts back toward level, existing drywall cracks may open or close and doors may need rehanging, because the house is returning to a shape it has not held in years. That is normal and is cosmetic. Abilene Foundation Repair marks every interior pier location before work begins so you can see exactly which flooring is in the path.
Yes — a lifetime transferable warranty on all pier installations, covering future settlement or movement on the sections we repaired. Transferable means it passes to the next owner if you sell, at no cost, which is worth real money during an Abilene home sale where buyers are wary of any disclosed foundation work. Read what the warranty is scoped to. It covers the piers we installed and the sections they support. It does not cover new movement in a part of the foundation we did not touch — if we pier the north side and the south side settles four years later, that is new work. Our inspection report names any areas we are watching but not repairing, precisely so that boundary is on paper from day one rather than argued about later. Abilene Foundation Repair issues the warranty certificate on completion; keep it with your closing documents.
