Abstract
The present invention provides methods and apparatus for soil stabilization. First, a void is formed in the compromised soil strata. Then, an expandable member containing expandable materials is placed into the void. As the material expands to fill the void, the surrounding soil is compressed. This in situ compression if the soil increases the load bearing capacity and compressive strength of the soil. Additionally, the present invention provides a method for isolating the injected materials from the environment at the injection and/or polymerization point.
