Concrete basement floors in Pittsburgh, PA
Plenty of Pittsburgh basements still have dirt floors, thin coal-era slabs or trenches left by a plumber. Getting concrete in is the hard part, and that is where we earn our money: pumping it through a window or wheeling it down the steps.

Getting concrete into a basement
Most Pittsburgh basements can't be reached by a truck, so we plan the route first. A small line pump can run concrete through a basement window from the street, and it is usually the cleanest way to go. On rowhouses and tight lots, we may wheel it through a side door or carry bags down the steps for a small patch. We lay down floor protection along the route, and we tell you up front what the pump costs.
Water, radon and old walls
A new floor seals the ground, and that changes how water moves. If your basement gets wet, plan the drainage first. An interior drain and sump pit are far easier to add before the pour than after it.
Radon is common in this part of Pennsylvania. A new slab is the best time to place a perforated pipe under the stone so a fan can be added later if a radon test calls for it. We don't test for radon or install fans, but we can set the pipe so you are ready.
Old stone and block walls also need care. A new slab should not undermine them. If you are digging down for headroom, the footers decide how far you can go, and that may need an engineer's plan.
Sealing and finishing the floor
If you will put flooring down, ask for a vapor barrier under the slab and a smooth trowel finish on top. Leave a new floor to dry for a month or more before gluing anything to it. To brighten and protect a bare basement floor, see concrete sealing or an epoxy coating. Sealing helps with dust and light dampness, but it won't stop water pushing through a failed wall.
How the work goes
- Check access and water
We plan the route in and look at drainage, walls and headroom.
- Prep the ground
We grade, compact and add stone, then lay the vapor barrier.
- Pump and pour
Concrete is pumped or carried in, then placed and screeded level.
- Trowel and cure
We finish the surface and leave it to cure slowly.
Common questions
How much does it cost to pour a basement floor?
Usually $8 to $14 per square foot around Pittsburgh. Hand carrying or a long pump run pushes it higher.
How much does it cost to pour a concrete basement floor?
An average 800 square foot basement often runs $6,500 to $11,000, depending on access and any digging needed.
Should I seal my concrete basement floor?
Sealing cuts dust and light moisture, and it makes cleaning easier. It won't fix active leaks, so deal with those first.
Do you need a vapor barrier under concrete?
In a basement, yes, especially if you will ever finish the room. It keeps ground moisture from coming up through the slab.
How thick is a basement floor?
Pennsylvania's code in 2026, the 2021 residential code, sets a 3 1/2 inch minimum for a slab floor, normally over a 4 inch stone base and a 6 mil vapor retarder; confirm current rules with your municipality. Many older Pittsburgh basement floors are thinner than that, sometimes an inch or two laid on dirt.
Why is my basement floor sweating?
Usually it is condensation. In humid summer weather, damp air meets the cool slab and leaves water on top, the way it beads on a cold glass, and moisture can also rise through an old floor with no vapor barrier. A dehumidifier deals with the first, and a new floor over a vapor retarder deals with the second.
