Most concrete repair fails the same way it failed the first time — because the underlying cause was never diagnosed. A crack is a symptom. The cause might be settlement, root heave from a mature oak, expansive clay swelling in winter, an over-watered planter washing fines out from under the slab, or a poorly placed control joint that the slab finally found a way around. Patching the crack without diagnosing the cause guarantees you'll be patching it again in 18 months.
Our repair work starts with a free on-site inspection. We probe joints, sound the slab with a chain drag, check for pumping at the cracks, look at site drainage, and identify any root or moisture sources within 10 feet of the affected area. Only then do we recommend a repair path: epoxy crack injection for structural cracks in walls, polyurethane foam injection (slab jacking) for settled slabs, partial-depth patching for spalling, full panel replacement for slabs past the point of cosmetic recovery.
Repairs include addressing the underlying cause where we can — installing a root barrier, redirecting drainage, removing the soft soil, or correcting the slope. A repair that doesn't fix the cause is a temporary cover-up at best. We tell you up front if the right answer is replacement, not repair.
