Low Density Cellular Grout & Flow Fill

Cellular Grout is ideal for filling annular space between the carrier pipe and the tunnel, filling voids using a low strength material and many types of backfill.  Some advantages are lower density and superior fluidity making it very easy to pump into place.
 
The density of lightweight grout is one-third to one-half as much.  This greatly reduces the possibility of deflection and flotation of the conduit.  The increased fluidity allows the cellular grout to readily flow into irregular voids and requires no consolidation.
