Unstable soil can be defined as soil that will not stay in place on its own, and there­fore requires extra support. It should be noted that unstable soil can threaten the stability, security, and safety of infrastructure and can damage, degrade, and even destroy a number of structures, such as buildings, bridges, and roads. There are a variety of factors that can cause unstable soil including erosion, poor compaction, freeze/thaw cycles and decomposition.

Alchemy-Spetec's H40 is a solvent and phthalate free, water reactive, hydrophobic, one-component low viscosity polyurethane injection resin designed for soil stabilization. You can use this product to stabilize soil underneath bridge approach slabs, warehouse floors, side walks and many other concrete structures.

You can also use H40 for curtain wall grouting, the process of injecting water reactive resin behind a leaking wall in a grid pattern. The water on the other side mixes with the grout and cures to a solid mass covering the surface of the wall on the other side.
