CAST-IN-PLACE FOUNDATION
Bentonite and polymer products are used to stabilize trenches or "panels" during excavation for foundations. Where space limitations do not allow for full excavation and forming, specialized contractors using unique equipment cut soil and use the trench walls as forms.
Hydro-mills or clam shells are used to excavate to depth. Slurries consisting of water and Hydrogel® and/or Kwik-Vis™ "D" pumped into the trench during the operation are used to support the walls.
Once excavated, the slurry is displaced with cement which cures and becomes part of the foundation wall. SW-101™ can also be used as it is resistant to the calcium contamination created from the cement pour.
