Technician injecting polyurethane to lift a settled garage floor slab

Foundation repair

Foundation Repair in New Mexico

Settled slabs, hollow spots, weak soil, and sinking footings. We lift and support foundations with polyurethane injection, and install piers when a footing needs to reach firmer ground.

Four ways we fix a settling foundation

Most foundation trouble comes down to the ground under it: soil that washed out, soil that was never compacted, or soil that can’t carry the weight. We pick the fix that matches the cause, and a lot of jobs need more than one.

Lifting settled slabs

When a slab foundation, a floor, or a slab-on-grade addition has dropped, we drill small holes and inject polyurethane foam underneath. The foam expands and raises the slab back toward level without tearing anything out.

Void filling

Water and settling leave empty space under slabs and footings. We fill it with foam so the concrete is carried again, often before it has dropped far enough to need lifting.

Soil stabilization

Where the soil under a foundation is loose or weak, we inject foam deeper into the ground to firm it up so it can carry the load.

Piers and underpinning

When a footing keeps sinking because the soil farther down can’t hold it, piers go in under the footing to carry the load down to firmer ground.

Signs a foundation is moving

  • Cracks that keep getting wider, or that are wider at one end
  • Stair-step cracks in block or brick
  • Doors and windows that start sticking or won’t latch
  • Floors that slope, or gaps opening under baseboards and at trim
  • A slab edge you can see daylight under, or soil washing out beside the foundation

What usually causes it here

  • Water in the wrong place. Roof runoff and canales dumping at the wall, irrigation, and leaking lines soften and carry off soil.
  • Soil that settles when it gets wet. Some New Mexico soils are dry and loose and pack down the first time they soak.
  • Fill that was never compacted. Dirt under additions, patios, and utility trenches keeps settling for years.
  • Soil that shrinks and swells. Clay soils in parts of the state move as they dry out and get wet again.

How a foundation job goes

  1. Site visit: We look at the cracks, check how far the floors are out of level, and look for where the water comes from.
  2. Written plan: Which method, where, and why, with anything that needs an engineer or another trade called out.
  3. The work: Small injection holes for lifting, void filling, and soil stabilization; excavation at the footing for piers.
  4. Check: We watch the structure while we lift, then re-check levels and patch the holes.
  5. Walk-through: We go over the result and anything around the house, like drainage, that should be fixed so it stays put.

What we’ll tell you up front

A foundation that settled over years may not come all the way back without cracking finishes. We tell you before we start what is realistic for your house.

Foam and piers put support back; they don’t stop the water that caused the problem. If a downspout, a leak, or the grading needs fixing too, it goes in the estimate or we point you to the right trade.

What to have ready

  • Photos of the cracks and the areas that have dropped
  • Whether the house is on a slab, a crawl space, or a basement
  • When you first noticed it and whether it is getting worse
  • Any water problems nearby: downspouts, leaks, irrigation, or standing water

Foundation Repair FAQs

No. Thin shrinkage cracks show up in most concrete and usually are not. The ones worth a look are cracks that keep getting wider, are wider at one end than the other, step through block or brick, or show up along with doors that stick and floors that slope. Send photos and we’ll tell you what we think.
It depends on how deep the problem is. When a slab dropped because the soil right under it washed out, compacted, or was never compacted well, polyurethane lifting, void filling, or soil stabilization usually handles it. When a footing keeps sinking because the soil farther down can’t carry the load, it needs piers to reach firmer ground. Some jobs need both. The estimate says which and why.
Often we can bring a settled slab or footing a long way back, but a house that settled over years may not come all the way back without cracking drywall, tile, or trim. We lift slowly, watch the structure as we go, and tell you before we start what is realistic for your house.
The repair puts support back where it was lost. Whether the foundation stays put also depends on the water: roof runoff dumping at the wall, a leaking line, or irrigation soaking the soil will keep working on it. We point out the causes we see so they can be fixed along with the foundation.
Some jobs do, especially larger pier jobs, structural damage, or a sale where the lender or buyer wants an engineer’s letter. We’ll tell you when a job needs one before we give you a price.
Send the report pages that mention the foundation, a few phone photos of each crack, and the address. Say whether the house is under contract and what the lender or buyer has asked for. Treat the inspector’s note as a starting point, not a diagnosis: at the site visit we check the floors with a level, look at each crack ourselves and trace where the water goes.
Not much for the estimate visit, since we mainly need to reach the cracks and walk the outside. For the work itself, the written plan shows where holes or digging go. Clear furniture and rugs off any drill spots indoors. Piers mean digging at the footing, so move any plants you want to keep from that spot, and show us any sprinkler line or buried pipe you know about.
