Concrete slabs provide the stable surfaces you rely on every day, from driveways and sidewalks to patios and porches. When these slabs begin to sink, settle, or become uneven, they can create tripping hazards, reduce curb appeal, and indicate that the ground beneath them is no longer providing proper support. Understanding what causes concrete slabs to sink can help you choose the right repair method and help prevent further damage.
JES Foundation Repair provides engineered concrete lifting solutions that restore safety, improve curb appeal, and deliver long-term stability without the cost and disruption of full slab replacement.
Sinking slabs often develop cracks, uneven sections, and depressions that create trip hazards, affect drainage, and diminish your property’s appearance. This problem most commonly affects driveways, sidewalks, patios, porches, and pool decks, where concrete is exposed to changing weather conditions, moisture, and shifting soil.
Concrete slabs sink when the soil beneath them shifts, erodes, or loses its ability to provide stable support. Common causes include poor drainage, soil settlement, erosion, and seasonal freeze-thaw cycles. Excess moisture is often a primary contributor because it weakens or washes away the supporting soil, causing the slab to settle over time.
Our trained and certified professionals repair sinking slabs using the SettleStop™ PolyRenewal™ system. This lightweight polyurethane foam is injected beneath the concrete to fill voids, restore support, and lift the slab. The minimally invasive process is quick and requires no heavy equipment or lengthy curing time. For more significant settlement, SettleStop™ Slab Piers may be recommended.
Our trained and certified experts inspect the affected concrete slabs and surrounding areas to determine the cause and extent of the damage. Based on our findings, we recommend a solution tailored specifically to your property’s needs.

Small holes are drilled into the affected slab, and our patented closed-cell polyurethane foam is injected beneath it. As the foam expands, it fills voids, stabilizes the underlying soil, and gently lifts the concrete back toward its original position. The foam cures in as little as 15 minutes, so the area is ready for use the same day.

In severe cases, slab piers may be installed to provide deeper structural support. These reinforcements extend into the stable soil layers below, ensuring long-term stabilization where foam injection alone isn’t sufficient.
