Unstable excavation walls create serious safety risks for crews and can jeopardize nearby structures. In dense urban settings, loss of soil support can compromise existing footings and adjacent improvements.
We performed chemical shoring using a single-component polyurethane soil binding system. Steel injection tubes were driven to the required depth and a low-viscosity polyurethane was injected to bind sandy soils and fill voids. In the presence of soil moisture, the product reacts and expands modestly, then cures over approximately 24 hours into a solid, excavatable mass, allowing excavation to proceed safely.
Explore Soil Stabilization →The excavation was stabilized quickly and reliably, improving jobsite safety and protecting surrounding structures. The contractor was able to continue work with confidence once curing was complete.
We inspect the site and measure the soil before recommending a repair.
