Concrete Stabilization Technologies provides ZERO EXCAVATION polyurethane injection foundation lifting. CST’s injection process stabilizes weak and poorly compacted soils beneath foundations and slabs. The primary cause of most foundation problems typically has to do with the support soil beneath the structure. When soils are poorly compacted, collapse, erode, expand or degrade, foundations are compromised. When soil lacks adequate density to support the foundation and structure, settling and movement can occur. CST’s Expanding Structural Polymer (ESP) injection technology densifies and recompacts soil and increases bearing capacity to properly support, lift, and level foundations and structures to original elevation without changing the foundation design and without ancillary costs. Our process is fast, non-disruptive, and safe.
