National cost ranges
| Method | National rate | When it's used |
|---|---|---|
| Push pier (steel underpinning) | $1,500–$3,000 / pier | Used for foundations that have settled due to unstable, expansive-clay, or poorly compacted soils, especially heavier single- and multi-story homes whose weight allows the piers to reach a firm stratum. |
| Slab-jacking (mudjacking / polyurethane foam lifting) | $3–$25 / sq ft | Used to re-level settled concrete slabs such as basement or garage floors, driveways, walkways, and patios where the slab is intact but has dropped due to soil washout or compaction. |
| Carbon fiber straps (bowing wall reinforcement) | $85–$275 / linear ft | Used on poured-concrete or block basement walls showing early-to-moderate bowing or horizontal cracking (generally under about 2 inches of deflection), as a non-excavation alternative to steel I-beams or wall anchors. |
| Basement waterproofing (interior / exterior) | $2–$15 / sq ft | Used when a basement shows water intrusion, dampness, efflorescence, or flooding, interior systems for managing moisture at lower cost, exterior systems for preventing entry in high-water-table conditions. |
| French drain / drain tile (interior or exterior) | $10–$100 / linear ft | Used to relieve hydrostatic pressure and redirect water where a yard, foundation, or basement repeatedly collects water; interior perimeter drain tile costs more due to concrete cutting and sump-pump integration. |
| Crawl space encapsulation | $3–$10 / sq ft | Used when a vented crawl space suffers from excess moisture, mold, musty odors, pests, or high indoor humidity that threatens air quality and framing. |
