When soil beneath concrete, asphalt, or structures becomes weak, saturated, or unstable, it can lead to settlement, surface deterioration, and structural instability. These conditions are often caused by erosion, poor compaction, excessive moisture, or freeze-thaw cycles, which reduce the soil’s ability to support loads.
Our Ground Stabilization service uses deep polyurethane injection to improve the compaction and load-bearing capacity of weak soils. Also known as deep soil injection, compaction grouting, or chemical grouting, this process involves injecting high-density, hydrophobic polyurethane foam into the ground at targeted depths. As the material expands, it fills voids, displaces water, and compacts surrounding soils, creating a stronger, more stable base.
This method addresses the root cause of settlement by strengthening the soil from within, helping stabilize foundations, slabs, roadways, retaining walls, and other infrastructure without excavation or major disruption.
Deep Ground Stabilization involves injecting polyurethane deep underground typically between 5 and 30 feet to fill voids, bind loose soils, and displace trapped water. Steel rods are installed to the desired depth, at which high density polyurethane is then injected through. The expanding foam then spreads through weak soil layers, compacting them from within and forming a strong, stable base, without the need for large-scale excavation. As the material cures, it increases the load-bearing capacity of the subgrade, increasing infrastructure stability.
This technique is effective for a variety of infrastructure application
Settlement in asphalt surfaces is commonly the result of subgrade movement, soil erosion, poor compaction, or loss of soil density beneath the pavement structure. If not addressed early, these conditions can create safety risks, accelerated surface deterioration, and expensive long-term repairs.
Deep Soil Injection (DSI) provides an effective method for stabilizing and improving the load-bearing capacity of underlying soils. By injecting high-density expanding polyurethane at targeted depths, weak or voided soils are compacted and reinforced, restoring structural support to the pavement above.
This minimally invasive approach allows municipalities and infrastructure managers to stabilize asphalt surfaces quickly with minimal disruption to traffic, while extending the service life of roads, parking areas, and other paved infrastructure.
