The problem

What we found

Even with strong geotechnical planning, localized conditions can vary outside test areas. At this site, certain zones showed settlement in asphalt drive lanes and near storage unit foundations, likely linked to unknown organic decomposition below grade.

The solution

How we repaired it

We drilled through the asphalt near the footings and drove steel injection tubes approximately 8 to 10 feet deep to treat soils beneath and adjacent to foundations. High-density structural polyurethane foam was injected to fill voids and increase load-bearing capacity. After completing injections, we patched access holes with asphalt cold patch to restore the surface quickly.

The result

What changed

Settlement concerns were addressed at depth and the driving surface was restored. The project delivered targeted stabilization while minimizing disruption to the facility.

Let us test what is underneath.

We assess the site and test the soil before recommending a repair.
