Large Void Filling Using An Expansive Foam
The injection of an expansive foam injection grout into a void space within various types of strata will fill the void, stop infiltration and stabilize the remaining soil.
The expansive foam is pressure injected from a remote pumping system. The liquid grout - with appropriate amount of necessary catalyst - is pressurized directly into the void space. When the injection grout comes into contact with groundwater or moisture from the soil, it expands and fills the void, stops active or potential water leaks and stabilizes the soils. Injection grouts react in minutes, but can be increased by adding additional catalyst to the resin.
