CNT Foundations

About

CNT Foundations serves South Carolina with foundation repair services from their Columbia base. The company holds a 4.5-star rating across 28 reviews and operates with 24/7 coverage. Their trained, certified experts assess damage and develop personalized repair plans, backed by a lifetime warranty. The business is locally owned, insured, and licensed. CNT Foundations addresses common foundation issues including foundation cracks (especially horizontal and stair-step patterns), uneven floors caused by moisture-damaged crawl space beams, bowing walls from hydrostatic pressure, gaps between walls and floors indicating foundation movement, tilting chimneys, and creaking or bouncy floors. The company recognizes these as signs requiring prompt professional attention. Their repair solutions include helical piers—steel shafts with screw-like helical blades drilled into stable soil to transfer foundation load and prevent settlement. They also offer underpinning, a process that reinforces existing foundations using piers selected based on foundation condition and soil characteristics. For concrete slab foundations experiencing cracking and settling, the company installs slab piers that extend to stable soil for necessary support. Additionally, CNT Foundations provides deep soil injection, a specialized technique using high-density polyurethane foam injected beneath the foundation to improve load-bearing capacity and compact surrounding soil. The company provides free estimates and can be reached at (843) 577-7268.
