Void Filling

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

  • Foundation Support
  • Retrofit of Existing Structures/Slab Jacking
  • Ground Improvement
  • Mitigating Water Seepage
