Subgrade Improvement for Structural & Pavement Support
Commercial structures and pavements rely on properly compacted soils to support loads. Over time, erosion, consolidation, or water movement can create voids beneath slabs and foundations. These hidden gaps reduce bearing support and may lead to settlement, cracking, joint separation, and structural instability.
PolyPier® systems are used to fill subsurface voids and stabilize soils by injecting expanding polyurethane material into the affected area. The material expands through the soil matrix, filling gaps, densifying loose soils, and restoring support without excavation.
When properly installed, void filling improves load distribution and helps prevent further movement in active commercial environments.
