Interior Flatwork
Utah Basement Slab, Garage, and Patios. These concrete surfaces form the basement floor, garage slab, and covered exterior pads. It's where precision meets durability.
What’s Included
This category includes labor and materials to pour and finish the interior basement slab, garage slab, and covered patio concrete. It includes formwork, reinforcement (wire mesh or fiber), and a smooth trowel or broom finish. Pricing varies based on square footage, thickness, and whether a vapor barrier or insulation is included. Uncovered flatwork (driveways, walkways) is typically bid separately.
Builder Tips:
Always confirm the thickness (typically 4" or 5") and whether gravel base and vapor barrier are included. Discuss finish type (trowel, broom, polished) and expansion joint layout before the pour. If pouring in cold weather, ask about additives or heating.
Consider radiant tubing now, even if you don’t plan to activate it immediately — it's hard to add later.
Real World Example:
A 4,200 sq ft home with a 2,000 sq ft basement slab, 850 sq ft garage slab, and 250 sq ft covered patio:
$5.75–$6.50/sf for basement slab
$6.00–$7.00/sf for garage (thicker & stronger)
$6.25–$7.25/sf for patio (exterior rated)
Total cost: $21,000–$25,000 depending on finish and thickness
FAQ
Q: Does this include the driveway and sidewalks?
A: No. Those are typically priced separately under exterior flatwork.
Q: What finish is standard?
A: Most basements are trowel or broom-finished. Patios and garages may use a broom or salt finish for grip.
Q: Is insulation or radiant tubing included?
A: Not usually — request these as add-ons. Radiant tubing must be installed before the pour.
Q: How long before I can walk or frame on the slab?
A: Light foot traffic in 24 hours. Framing usually starts after 5–7 days.
