Greenfield Concrete Leveling FAQ
Who handles sidewalk permits in Greenfield?
The city's Engineering Division reviews, issues and inspects sidewalk permits. If your slab is a public sidewalk, check with them before any work, including lifting, and we will plan around their answer.
Where should my sump pump discharge in Greenfield?
The city's clear water program says sump water goes to the storm sewer or onto the ground around the house, never into the sanitary sewer. Point it away from driveways and walks too, because it can wash out the soil under them.
Why does concrete settle so much here?
Most of Greenfield has soils that drain slowly when wet, with some clay that swells and shrinks. Sixty years of freeze and thaw, plus water from downspouts and sumps, wears away the support under a slab.
Is it worth lifting an older driveway instead of replacing it?
If the slab is still in one piece, usually yes. Lifting costs a fraction of replacement, there is no tear-out, and you can drive on foam-lifted concrete the same day. If it is badly broken up, we will tell you.
Is foam lifting or mudjacking better for my concrete?
Both raise concrete by pumping material underneath it. Polyurethane foam is light, needs smaller holes and cures in minutes, so it suits most driveways, walks and garage floors on clay soil. Traditional mudjacking still makes sense on some larger slabs. We look at the slab and the soil and tell you which one we would use and why.
How soon can I use the slab after it is lifted?
With foam, you can usually walk on it right away and drive on it the same day. Mudjacking takes a little longer to set. We tell you exactly when it is ready before we leave.
Do you serve the area around Greenfield?
Yes. We work in Greendale, Hales Corners, West Allis, Franklin and Milwaukee, plus the rest of Milwaukee, Waukesha, Ozaukee, Washington and Sheboygan Counties.
