How Much Does it Cost to Repair a Slab Foundation?

Concrete slab foundations are typically smaller than commercial structures, making them less expensive to repair. The type of foundation you have, such as concrete slabs, dock foundations, crawl spaces, or basement foundations, will determine the solution used to repair your foundation. Shoring is the most common method for concrete slabs, while reassembly or relocking is usually used for access spaces or pillars. If you notice external or internal cracks in walls, doors or windows that don't close properly, or mud theft or roughing, contact a qualified slab foundation repair company right away.

All of these factors will influence the cost and type of support method that best suits your situation. Severe weather events, pipe leaks, and groundwater flow can damage concrete slabs. The slab can be floated back to its original position by pumping a mixture of sand, cement, fly ash and other additives through small holes. The best way to save money on slab foundation repair is to address the underlying problem as soon as possible.

Leaks usually point to drainage and moisture issues, which can be solved with waterproof sealing around the structure. Get an inspection from a structural engineer to find out the extent of your repair needs so you don't pay for unnecessary services. Depending on the extent of the damage, the owner of the house can repair some cracks, but it is better for a professional to conduct an assessment first. Before you can get an accurate estimate of the cost of repairing your foundation, the foundation and surrounding area will need to be inspected by an expert contractor.

When contractors and structural engineers erect foundations, they calculate overhead costs based on how high the foundation should be raised and the type of foundation the house has.
