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 property and can damage, degrade, and even destroy a number of structures, such as residential dwellings, garages, driveways, and pool decks. There are a variety of factors that can cause unstable soil including erosion, poor compaction, freeze/thaw cycles, and decomposition.
Soil can be stabilized with:
AP Soil 600
AP Fill 700
AP Fill 720
AP SoilGel 200
Once the bearing capacity of the soil has been increased with this process, then the structure can be lifted if necessary.
