Frequently Asked Questions
How much does a concrete slab cost in Texas?
A standard 4-inch concrete slab in Texas costs $6 to $10 per square foot fully installed. A heavy-duty 6-inch slab with rebar runs $8 to $14 per square foot. A 10x12 shed pad costs $800 to $2,000. A 20x20 garage slab runs $3,000 to $5,000. A small AC equipment pad costs $300 to $600. Site excavation on clay soil adds $2 to $5 per square foot. Pricing varies by region and soil conditions.
How thick should a concrete slab be in Texas?
Slab thickness depends on the intended use and soil type. Pedestrian-only slabs like patios need 4 inches minimum. Vehicle slabs like driveways and garages require 5 to 6 inches. Building pads for structures require 4 to 6 inches with thickened edges per engineering plans. On Texas expansive clay, many engineers specify thicker slabs with additional reinforcement to resist soil heaving forces. Always follow local building code requirements.
What base preparation is needed on Texas clay soil?
Texas expansive clay soil requires thorough base preparation to prevent slab cracking and heaving. Standard preparation includes excavating 6 to 12 inches below grade, installing geotextile fabric to separate clay from aggregate, placing and compacting 4 to 6 inches of crushed limestone in lifts, and moistening the subgrade to near-optimum moisture content before pouring. Skipping proper base prep on clay soil virtually guarantees slab failure within five years.
Does a concrete slab need reinforcement?
Yes, all concrete slabs in Texas should include reinforcement. Minimum is welded wire mesh for light-duty slabs. Garage and building slabs require number 3 or number 4 rebar on 18 to 24 inch centers both ways. Fiber mesh mixed into the concrete controls surface cracking. On expansive clay soil, post-tensioned slabs with steel cables are common for building foundations. Your engineer or contractor specifies reinforcement based on slab purpose and soil conditions.
Do I need a permit for a concrete slab in Texas?
Permits are typically required for slabs intended as building foundations, room additions, or detached structures over a certain size. Small equipment pads, shed pads under 120 square feet, and freestanding patios usually do not require permits in most Texas cities. Check with your local building department, as rules vary significantly between jurisdictions. Unpermitted structural slabs can create problems when selling your home.
How long should I wait before putting weight on a new slab?
Light foot traffic is safe after 24 to 48 hours. Place a shed or storage building after 7 days. Park vehicles on garage slabs after 7 to 10 days. Full design load for building foundations is reached at 28 days. In Texas summer heat, concrete gains early strength faster but still needs the full cure period for maximum durability. Wet curing for the first 7 days is critical regardless of ambient temperature.
