Concrete Slabs and Foundations in Dallas

Usually permit fees, demolition of the old concrete and drainage work. A Dallas range of $6 to $11 per square foot for reinforced pours usually leaves out permit fees (an estimated $107–$300+ through DallasNow), demolition of existing concrete ($1.10–$1.80 per square foot) and drainage work. A slab foundation of 800–1,200 square feet comes to $4,600–$12,120 in total. Ask the company to list excavation, base, vapor barrier, steel and finishing, then check the full Dallas cost guide.

Two inspections come before the pour. The Dallas city code calls for a footing and foundation inspection after the excavation is dug and any required reinforcing steel is in place. A separate slab and under-floor inspection comes after the in-slab steel and building service equipment are set, before any concrete is placed. The code also names foundation contractors, who pour and finish concrete foundations and structural elements, as a class that registers with the city. More on who pulls the permit in the permit guide.

Because it moves with the weather and can crack a slab that isn't built for it. Houston Black, a clay soil mapped across the Blackland Prairies of east-central Texas, cracks when it dries: federal soil surveys record cracks 0.5 to 4 inches wide that stay open for 90 to 150 days in most years. North Texas's expansive clay and temperature swings can crack a slab that isn't properly reinforced. For anything structural, such as a room addition, Frisco requires an engineer of record for residential structural and foundation work to register before permits are issued.

No. Repairing a house foundation is structural work with its own permits: Arlington, for example, has required building permits for structural repairs to foundations since November 1, 2011. Requests through this site are for new slabs, pads and flatwork. For a garage floor or shed pad, compare it with a new driveway, which faces the same soil.
