Slab Foundation Repair in Knoxville, TN
Newer homes, additions and garages around Knoxville are often built on concrete slabs. When the soil underneath settles or washes out, the slab cracks and sinks.
Request a foundation inspectionWhy slabs settle
Fill soil that wasn't compacted well, water washing out soil under the edge and clay drying in a long dry spell can all leave voids under a slab.
Signs
Cracks in tile or concrete floors, gaps between the floor and baseboard, doors out of square and sloping floors are common signs.
Piering
Settling slab foundations can be supported with steel piers driven to firm soil and lifted back toward level.
Slab lifting
Sunken garage floors, patios, sidewalks and steps can often be raised by injecting foam or grout under them, which is quicker and cheaper than replacing them.
Plumbing leaks
A leak under a slab can wash out soil. If you see damp spots or hear water running, have the plumbing checked.
Additions
A slab addition attached to an older house can settle differently from the main home, leaving a crack at the joint.
Drainage
Water pooling against a slab edge is often the root cause. Grading and downspout extensions help.
Garage floors
Cracks in garage floors are common and often cosmetic. Sinking near the door can let water in.
