How We Help With Mudjacking & Concrete Lifting

Sunken or uneven concrete slabs are both a trip hazard and a drainage problem on Thousand Oaks residential properties. Driveways, sidewalks, pool decks, and garage floors can sink when the compacted fill soil beneath them settles, erodes, or washes away. Best Foundation Repair offers both traditional mudjacking (slabjacking) and polyurethane foam lifting as cost-effective alternatives to complete slab demolition and replacement. Traditional mudjacking pumps a cement-soil-water slurry through drilled holes in the slab to fill voids and hydraulically lift the concrete back to grade. Polyurethane foam injection uses an expanding two-part foam that achieves the same result with smaller drill holes, faster curing, and less added weight.

The process for both methods begins with mapping the settled slab and identifying void locations, followed by drilling a pattern of holes—typically 1.5 to 2 inches for mudjacking and 5/8 inch for polyurethane. Material is injected at controlled pressure and volume, and the slab rises gradually as the technician monitors elevation with a level. Holes are patched after lifting is complete, and the slab is ready for traffic within hours for polyurethane or one to two days for traditional mudjacking slurry. The result is a leveled surface that eliminates trip hazards and restores proper drainage away from structures.

Concrete lifting is typically 50–75% less expensive than full slab replacement and preserves the existing concrete, which is better for the environment and faster for the homeowner. Best Foundation Repair evaluates each slab to confirm it is structurally sound enough to lift—heavily cracked or deteriorated slabs may require replacement—and provides honest recommendations so you invest in the right solution the first time.
