Settled Patio? Epp Lifts the Slab and Stabilizes the Soil Beneath It.

Polyurethane foam patio lifts run $5 to $25 per square foot depending on lift height and access. A typical patio lift-and-seal job is $800 to $4,000. Crack sealing alone runs $200 to $600 per crack. Written estimate after on-site inspection reflects your actual scope.

Replace when most of the surface is spalling deeper than 1/4 inch, when there are multiple structural cracks (not just joint cracks), when the slab has settled more than 4 to 6 inches and lifting would over-stress the concrete, or when the patio has reached end of useful life. Epp's inspector says so on the report when replacement is the right call. Roughly 1 in 10 patio inspections in 2024 went that way.

Settled patios show even cracking along the low side, a visible dip when measured with a 4-foot level, and the slab itself is otherwise sound. No spalling, no scaling. Failing concrete shows surface deterioration first: pitting, scaling, exposed aggregate, and structural cracks that don't follow the settlement pattern. Epp's inspector documents both on the estimate so the diagnosis is on paper, not assumed.

No. Epp lifts, seals, and stabilizes existing concrete. Epp doesn't pour new flatwork. When a section needs replaced, the inspector flags it on the estimate and the homeowner coordinates a flatwork contractor for that portion. Epp can still lift and seal the salvageable sections.

No. The foam expands at a controlled rate, the technician injects in 1- to 3-pound increments through multiple ports, and the slab is monitored with a laser level throughout. Foam pressure is well below the tensile strength of intact concrete. If the slab has pre-existing structural cracks the inspector flags them before lift; foam can sometimes propagate a hairline crack, which is why Epp seals working cracks as part of the standard scope.

When the soil cause is addressed. Downspout repositioned, grade corrected, root issue managed. A polyurethane foam lift lasts 10 to 20-plus years. The foam itself is inert and doesn't degrade. The limiting factor is whether new water is allowed to wash fines out of the base again. Epp's inspector names the drainage issue on the estimate so the homeowner can act on it.

Yes. Polyurethane foam is preferred over mudjacking within 5 feet of a foundation wall because foam doesn't add load to the soil column. Mudjacking slurry weighs about 100 pounds per cubic foot and can push laterally against the foundation if the void is large. Foam at 2 to 4 pounds per cubic foot finished density is the safe choice near the house.
