Why Use Chemical Grout for Joint Sealing?
Polyurethane chemical grout is a fast and effective process for culvert repair and rehabilitation. When chemical grout is injected into the soil, it initially moves in liquid form, actively finding voids and gaps in and around the culvert, lateral line, or manhole. After it reacts, the chemical grout expands throughout the soil media, compacting and bonding the soil while sealing the joint against further infiltration.
Polyurethane Injection
Polyurethane injection is a fast and effective method for lifting and leveling concrete slabs, filling voids, and soil densification. Applications range from residential slab lifting and foundation repair to commercial soil densification and slab lifting to infrastructure services such as lateral line joint sealing, dam stabilization, and roadway leveling.
Soil Compaction with Polyurethane
Polyurethane chemical grout is an excellent in-situ solution for densifying and binding loose and unconsolidated soils. It works in the following stages:
- The polyurethane initially saturates the voids and loose soils in a liquid form.
- The polyurethane expands throughout the voids and binds and compacts the soil together.
- The voids and soils are now locked together in a dense matrix of soil and polyurethane.
