Grand Prairie, TX · Foundation Specialist

Pinnacle Foundation Repair is based in Grand Prairie, TX, and performs foundation repair on residential and commercial properties. Its stated service area covers Grand Prairie, Plano, Dallas, Fort Worth, Lewisville, Frisco, and Denton. For slab foundations, the company offers steel pier installation, steel transition pier installation, drilled pier installation, and mud jacking. The company's site describes steel piers as interlocked 12-inch steel pipes with a friction reduction plate, filled with cement, and drivable up to 75 feet into the ground. Steel transition piers combine double-walled steel with high-strength concrete. Drilled piers measure 12 to 18 inches in diameter, are reinforced with rebar and a five-sack concrete mix, and reach approximately 12 feet into the ground. Mud jacking introduces a mixture of screened topsoil and cement beneath a slab through a two-inch drilled hole. For pier and beam and block and base foundations, the company's site describes services that include wood replacement, pad and block systems, poured-in-place piers, and shimming of existing piers. Additional services described on the site include drainage correction through the installation of surface drains with low-profile catch basins and deep French drains; spread footing, which involves digging a haunch below the existing structure and filling it with rebar-reinforced concrete; and tunneling to reach the foundation from beneath the home without disturbing interior flooring. During initial evaluations, the site describes the use of ground-penetrating radar to image the foundation and identify slab thickness and the location of interior grade beams before work begins. The site also describes a process in which a non-affiliated structural engineer reviews and signs off on foundation plans before repairs start and inspects the completed work afterward. Pinnacle Foundation Repair holds a 5.0 rating from 2,558 Google reviews as of 2026-08-03.
