Interior slab settled? Epp lifts the floor without tearing it out.

Residential interior slab leveling in Nebraska, Iowa, Kansas, and Missouri typically runs $1,500 to $8,000 depending on the area lifted and the lift height. A single settled basement corner falls between $1,500 and $3,000. A full interior room on a slab-on-grade ranch home runs $3,000 to $6,000. Polyurethane foam pricing in this region averages $5 to $25 per square foot of slab lifted, with the per-square-foot price dropping on larger areas. Floor finish, port count, and accessibility through narrow basement stairs or finished spaces affect the final number. Written estimate after on-site inspection reflects your scope.

Lifting is not appropriate when the slab has cracks wider than 1/2 inch through its full thickness. That slab needs replacement, not lifting. It is not appropriate over an active plumbing leak below the slab; the leak has to be repaired first because it will recreate the void. Lifting is also the wrong call when the cause of the settlement is foundation wall movement (the wall is pulling the slab edge with it. A separate scope), when settlement is widening and active, or when the void is deeper than 6 feet below the slab and slab piers are the correct fix. Epp's diagnostician identifies which category your slab falls into before quoting.

Epp Foundation Repair maps floor elevation in a grid pattern with a digital level or laser, locates the low and high points, identifies and measures every visible crack, checks slab plumbing for active leaks with a pressure test, and probes through a small test bore in a discreet location to confirm sub-slab soil type and moisture content. The settlement pattern tells us the cause. Perimeter drop points to backfill consolidation, center drop points to plumbing-leak voids or poor sub-slab fill compaction, local depressions point to discrete voids. The diagnosis takes 60 to 90 minutes. We will not quote a lift method before we know what is below the slab.

Epp Foundation Repair drills 5/8-inch ports through whatever floor finish is in place. Carpet, tile, vinyl, hardwood, laminate. Drop cloths and dust containment protect the surrounding finish during drilling. After the lift, ports are patched flush with color-matched concrete patch material. Restoring the floor finish above the patch is the homeowner's responsibility, typically handled by a flooring contractor as a separate step. Carpet seams can be re-stretched and re-tacked, tile can be replaced from owner-supplied spares, vinyl can be patched with a piece from a closet or under an appliance. Epp will tell you up front what the floor restoration will look like before drilling so there are no surprises.

Polyurethane foam injection on an interior slab uses two-part polyurethane resin pumped through 5/8-inch ports drilled through the floor finish and the slab on 4- to 6-foot centers. The resin expands 20 to 30 times its liquid volume, fills voids in the sub-slab fill, compacts loose loess or fine sand, and lifts the slab in measured increments. Foam cures in about 15 minutes per port; the slab is walkable the same day. The foam is inert, hydrophobic, and does not break down. It will not wash out or lose volume over time. Foam is also the right choice over clay soils because it does not re-saturate the clay the way cement slurry mudjacking can.

Slab-on-grade homes built in eastern Nebraska and western Iowa from the 1960s through the 1990s routinely used on-site loess or fine sand as sub-slab fill, placed in 12- to 24-inch lifts without modern compaction standards. Loess is structurally stable when dry but loses volume when saturated. A soil failure mode called hydroconsolidation. Over 30 to 50 years the fill slowly consolidates, especially after a saturating event like a slab plumbing leak or a wet basement year, and the slab drops 1 to 3 inches. After 30 years of repairs across Lincoln, Omaha, Council Bluffs, and Des Moines, we see this pattern constantly in pre-2000 ranch and split-level homes.

No. Interior slab lifts are completed in a single day on most residential jobs. The crew works one section at a time, the foam cures in about 15 minutes per port, and the slab is walkable immediately. Dust containment limits drilling debris to the work area. Furniture in the lift zone is moved by the homeowner before the crew arrives. Epp does not move furniture as part of the scope. Heat, electricity, and water service to the rest of the house are not affected by the lift. Most homeowners are back to normal use of the room the same evening, with the only remaining step being floor finish restoration over the patched ports.

When the sub-slab cause is properly addressed by filling the voids with polyurethane foam, and when no active plumbing leak or moisture source is left in place to recreate new voids, an interior slab lift on a hydroconsolidated loess fill or a stabilized clay subgrade typically holds the lifetime of the home. The foam itself is permanent. It does not break down, wash out, or lose volume. Re-settlement after a foam lift means new void formation, almost always from an unaddressed plumbing leak or a drainage problem changing the sub-slab moisture. Epp's transferable lifetime warranty covers further foam-related settlement; it does not cover settlement from a new leak or drainage failure introduced after the lift.
