Why does concrete settle?
-Concrete can settle for a number of reasons. But these are the most common contributors.
- SOIL COMPACTION: If the soil isn't compacted enough before the concrete is poured, it can erode and create voids under the slab, causing the concrete to sink.
- MOISTURE: When soil absorbs water, it expands, and then contracts as it dries out. This constant fluctuation can cause the concrete to settle. Freezing and thawing in the winter can also break down the soil, making it weaker and less able to support the concrete.
- DRAINAGE: Poor drainage can cause channels to wash out the soil under the concrete, causing it to sink.
- GROUND SLOPE: If the ground slopes towards the concrete, water runoff can seep into the soil and create instability, leading to sinking.
- EROSION: Soil can be washed away from under the concrete, creating a void that the concrete will settle into
WHY DO SOMETHING ABOUT IT?
TRIP & FALL LAWSUITS
STAYING WITHIN ADA COMPLIANCE
STAYING WITHIN ADA COMPLIANCE
- The average trip and fall lawsuit settles for over $50,000 dollars.
- You are liable for sunken settled concrete on your property.
- Viewed as negligence in litigation.

- Raised or sinking concrete where the change in level is above ¼ inch is considered a trip hazard and must be taken care of to meet ADA requirements.

- Keep those who live at and visit the property safe by correcting sunken settled concrete issues.
- Children and others can stub toes, trip, fall and get hurt.
HOW DO WE DO IT?
STEP 1. DRILL
We begin by drilling holes about the size of a penny into the sunken cement. Injection ports are installed to allow controlled injection of the polyurethane foam.
STEP 2. PUMP
Using a specialized injection gun, a two-part geotechnical polymer forms a foam that fills the gaps where the soil has settled or washed away.
PART 3. RAISE
As the injected polyurethane foam expands beneath the concrete slab, it fills the voids and lifts the cement. Our technicians carefully raise the slab to the desired height.
PART 4. PATCH
The drilled holes used for injection are patched with grout, making the fact that work was done unnoticeable. The foam fully hardens within 15 minutes, allowing you to use your concrete surface almost immediately.
