Permeation Grouting Of Soil

Scope of Work: Injection of permeable, failing substrates to stabilize soil with polyurethane chemical grouts.

Problem: Water migration through poor or loose soil substrates (sandy soils, poorly compacted fill, etc.) results in erosion, movement and/or loss of soils causing failure in above- and below-grade structures such as slabs, foundations, roadways and bridges.

Solution: Inject slow-reacting polyurethane resins slowly into the soil in order to stabilize the substrate. The resin turns into a foam that binds the existing soil components together.
