Concrete company in Mt. Lebanon, PA
Mt. Lebanon grew fast as a streetcar suburb after the Liberty Tubes opened in 1924, from about 2,300 people in 1920 to more than 13,000 by 1930. Many of its Tudor, Colonial and Craftsman homes date from that boom. They sit on streets that curve with the hills, over basements that are now close to a century old.

When the basement floor takes on water
On a hillside lot, the uphill side of the house has soil and groundwater pressing against it, and after a long rain that water looks for a way in. It often shows up at the joint where the floor meets the wall, or as one damp patch that never quite dries. Floors of this age were rarely poured over a vapor barrier, so dampness can also rise straight through the slab.
The fix usually starts outside, with gutters and grading, then moves to the floor. Where the old slab is broken or damp throughout, a new basement floor goes in over stone and a vapor barrier, sometimes with a perimeter drain to a sump. A floor drain usually adds $500 to $1,500 during a replacement.
Outside, the same slopes make slabs hard to keep level. A back slab cut into the hill on one side and built up on the other will settle on the filled side, unless that fill goes in thin compacted layers or the low edge is carried on a thickened footing. In Virginia Manor and other plans where the streets follow the contours, the downhill side of a lot is often where that fill sits. Many homes here are inside the Mt. Lebanon Historic District, listed on the National Register, so for work that shows from the street, ask the municipality whether any review applies.

Concrete questions from Mt. Lebanon
Why is my basement floor wet in one spot?
Check for a leaking pipe, a floor drain backing up or a downspout emptying close to the wall first. If the spot is at a crack or by the uphill wall, it is usually groundwater coming through.
How to fix cracked and sinking concrete?
Find out what moved it, usually water or a soft base. Sound slabs can be lifted and the cracks sealed. Broken or badly sunken ones are better cut out and replaced on compacted stone.
Can a concrete company replace a damp basement floor in a Mt. Lebanon home?
Yes. A new basement floor usually runs $8 to $14 per square foot, with stone and a vapor barrier under it. If water is coming in at the walls, we will say so, because a new floor alone will not stop that.
Will a back slab settle on a sloped Mt. Lebanon lot?
It can, on the side that was built up with fill. Compacting that fill in thin layers, or carrying the low edge on a thickened footing, keeps the slab from tipping. Slabs usually run $7 to $12 per square foot.
