If it sits on or in the soil, the chances that it will eventually move is the surest bet one can make.

GEOTECHNICAL SOILREPAIR

Foundation Technology offers geotechnical services such as soil repair and soil stabilization services for beneath your structure or slab, that has been disturbed, altered, or become unstable for any reason after the structure has been built.

The soil beneath your structure is never static. Excess moisture, drought cycling, seismic activity, man-made vibration, erosion, plumbing failures, and material degradation all alter the load-bearing characteristics of the soil your foundation depends on. When those conditions change enough, the structure above responds — with settlement, lateral movement, cracking, and progressive structural failure.

Foundation Technology stabilizes and remediates compromised soils beneath existing structures — quickly, efficiently, and without the need for excavation, removal, or recompaction. Our geotechnical solutions address the full range of soil-related structural problems:

Void filling beneath slabs and foundations · Soil stabilization after plumbing leaks or sewer line repairs · Erosion control from underground water seepage · Hillside stabilization after fire, flood, or grading failure · Soil reinforcement beneath high-water-consumption areas, tanks, and equipment pads · Stabilization of sea walls, bridge abutments, and retaining structures compromised by soil loss

Soil stabilization: a general term for any physical, chemical, mechanical, biological or combined method of changing a natural or previously altered soil to a more stable or sound support for the structure embedded or sitting upon that soil.

Soil Elasticity and Swelling of Clay Soils

Clay soils swell when they absorb moisture and shrink when they dry out. That cycle — measured by the soil’s plasticity index — lifts foundations, fractures slabs, displaces structural elements, and creates voids beneath your building. The damage is cumulative. Every wet-dry cycle makes it worse, and the concrete above has no way to absorb the movement without cracking.

There is no single solution for every expansive soil condition. Chemical injection, polyurethane deep soil injection, mechanical stabilization, and moisture management systems all address the problem differently — and the right approach depends entirely on your site’s geotechnical data, soil composition, moisture profile, and the type of structure being affected. Foundation Technology evaluates each project individually and engineers a stabilization solution matched to your specific conditions — not a default product applied regardless of the soil mechanics involved.

Chemical soil injection, for example, introduces non-toxic, water-soluble compounds into the clay beneath your structure that reduce the soil’s ability to absorb moisture — limiting further swelling and preventing additional displacement. It’s highly effective in the right conditions, but it’s one tool in a broader capability set, not our only answer.

Expansive soil stabilization spans virtually every commercial sector — airport runways and taxiways, commercial retail centers where landscape irrigation drives soil movement, new construction on high-plasticity sites, agricultural processing yards, theme parks, institutional campuses, and any facility with significant water usage near slab-on-grade construction.

If your slabs are lifting, your floors are uneven, or your foundation is showing signs of expansive soil damage — the cycle is already in progress. [Contact Our Geotechnical Team] · (661) 294-1313
