Lift Sunken Concrete Slabs Back Toward Level With Polyurethane Foam

No. Epp Foundation Repair does not perform, quote, or warranty mudjacking, the older method that pumps a heavy cement based slurry through holes roughly 1 1/4 inch across. Every flatwork lift Epp completes, from driveways and sidewalks to patios and garage approaches, uses polyurethane foam injection instead, because the lighter foam load does not add weight to soil that has already failed to support the slab once. Slab jacking is the broader term for lifting a slab by injecting material beneath it; Epp's version of that service is always foam.

A properly done foam lift can last many years and often the remaining life of the slab, as long as the reason the soil moved in the first place is corrected. Epp Foundation Repair fills the voids and gives the slab a firm base, but if a downspout keeps dumping water at the slab edge or a clay soil keeps drying and shrinking, the ground can move again over time. That is why the crew points out the cause and recommends simple fixes like redirecting a downspout. The cured foam itself does not break down underground.

Yes. Foam injection works well on driveways, garage approaches, sidewalks, patios, and pool decks. These are exactly the flatwork slabs that settle most often because they sit on fill soil and take weather and erosion at their edges. Epp Foundation Repair raises this kind of concrete across its four-state service area regularly. The method does not apply to a settling foundation footing under your house, which needs piers instead.

When the slab is still in sound condition, lifting it is usually faster and costs less than tearing it out and pouring new concrete, and you keep the original slab and its weathered match to the rest of your concrete. Replacement makes more sense when a slab has broken into several loose pieces, has crumbling edges, or has dropped so far that lifting it evenly is not realistic. Epp Foundation Repair gives you a straight answer at the inspection rather than pushing the more expensive option.

Epp Foundation Repair uses a two-part polyurethane foam that starts as two liquid components and expands within seconds of mixing at the injection gun, curing to a firm, lightweight, closed-cell fill under the slab. It weighs far less than the cement based slurry an older lifting method uses, so it reaches through smaller ports and adds much less load to the soil. The choice of port size and foam volume depends on slab weight, soil, and access, and the crew explains the plan for your job.

Foam injection typically runs a few hundred dollars for a single small slab section up to a couple thousand dollars or more for a full driveway or large patio, depending on slab size, how far it has settled, and how much foam the voids take. Cost varies a lot with the specific slab, so any number here is a rough guide. A Customized Repair Estimate after an on-site inspection reflects your scope. Epp Foundation Repair does not price a slab sight unseen.

A settled slab rarely settles just once. The void under it usually keeps growing as water erodes more soil or clay keeps shrinking, so the drop gets worse and the slab is more likely to crack into pieces that can no longer be lifted. A sidewalk panel that catches a toe today becomes a trip hazard and a liability tomorrow, and a driveway that slopes toward the house sends water at your foundation. Acting while the slab is still sound is the difference between a same-day lift and a full tear-out and replacement.
