Unstable Garage Slabs = Danger
The weight of the average automobile is currently around 4,000 pounds. When dangerous voids or unstable soil undermine your garage floor slab, you are parking that two ton machine on a surface that could possibly collapse.
Lest you think we're exaggerating, take a look at this 5th anniversary video of the floor collapse at the National Corvette Museum. The video contains a recording of the 911 emergency call, juxtaposed against security cam footage of the concrete slab collapsing - taking some Corvettes with it.
Polyurethane Slab Repair
A homeowner in Acworth, GA recently noticed that his garage floor was depressed in the middle - bowing down towards the center of the garage. He wisely called Ground Consolidation Services. Our crews used Alchemy-Spetec's AP Lift 430 polyurethane foam to stabilize the soil deep beneath the slab and also to lift it back into place.
See the before and after photos: The string was secured at either end of the garage - revealing the 1.75" depression in the middle of the slab before the repair AND the almost non-existent depression after the repair.
