Void filling is a technique used to stabilize the subsurface and prevent settlement of structures, resulting from natural or man-made cavities forming in the soil. These voids can be reduced or eliminated using fill such as Portland cement, cementitious and/or chemical grouts, and/or expansive polymers/foams. To perform this work, a drill string or pipe is typically advanced into the void, after which the selected material is pumped into place and allowed to cure.
Typical Applications for Void Filling
Retrofit of Existing Structures/Slab Jacking
Mitigating Water Seepage
