Concrete Stabilizing

Concrete stabilizing is a proactive solution designed to support concrete slabs before they settle or fail. At Level Best Northwest, we stabilize concrete by filling voids beneath the slab with polyurethane foam, preventing future sinking, cracking, and structural issues. This process protects your existing concrete, improves safety, and helps avoid costly repairs or replacement down the road, all with minimal disruption to your property.

Is Your Concrete Showing Signs of Damage or Wear?

Concrete does not fail overnight. In many cases, problems begin beneath the surface, where soil erosion or compaction creates voids under otherwise level slabs.

Common signs concrete may need stabilizing include:

  • Hollow sounds when walking across the concrete or bouncing a ball

  • Visible gaps beneath the slab when viewed from the side

  • Early or excessive cracking, even though the slab has not visibly sunk

  • Concrete near buildings where doors or windows begin to stick as slabs shift

  • Areas where water collects or flows toward cracks instead of away from structures

Unstable concrete is a safety concern and can lead to additional damage over time. Cracks allow water to enter, which accelerates soil erosion and freeze-thaw movement. Left untreated, these early warning signs often lead to settlement, uneven surfaces, and more extensive repairs.

How We Restore and Protect Your Concrete

Concrete stabilizing is ideal when voids exist beneath a slab, but the concrete itself has not yet significantly settled. In these cases, stabilizing the soil early can prevent the slab from sinking in the future.

Our concrete stabilizing process:

  • We assess the concrete to identify voids and areas of unstable soil

  • Polyurethane foam is injected beneath the slab

  • The foam expands to fill empty spaces and compact loose soil

  • The slab is stabilized and supported, reducing movement and future cracking

This process works well for:

  • Sidewalks and walkways

  • Driveways and garage floors

  • Pool decks and patios

  • Interior slabs and hard-to-reach areas

Because the foam is lightweight and waterproof, it provides long-term support without adding stress to the soil or surrounding structure.

Why Repairing Concrete Is Often the Better Option

Concrete stabilizing offers a practical alternative to full replacement, especially when problems are caught early.

Benefits of concrete stabilizing:

  • Prevents future settlement by addressing soil issues before slabs sink

  • Costs less than half the price of replacing concrete

  • Takes less time, with minimal disruption to daily activities

  • Improves safety by reducing cracking and uneven movement

  • Eco-friendly, since existing concrete stays in place and out of landfills

By stabilizing concrete early, you protect your investment, reduce long-term maintenance costs, and avoid unnecessary demolition. It’s a smart solution for homeowners and businesses looking to maintain safe, stable concrete surfaces.
