What are the different methods of foundation repair?

Foundation repair methods vary based on the type and severity of the damage. Common techniques include underpinning (installing additional support beneath the foundation), slabjacking (lifting a sunken concrete slab), helical piers (screw-like piles driven into the ground for support), carbon fiber reinforcement (strengthening walls with carbon fiber strips) and crawl spaces structural repair (replacing dry rotted joists and beams, as well as lifting and leveling.).
