Underlying Voids

Underlying Voids - Void Spanning

When there is a danger of collapse into underlying voids, a reinforced basal layer may be constructed by using either Tensar biaxial geogrids with granular fill to form a stiffened raft, or Tensar Basetex, as a tensioned membrane, to span over voids. In certain locations this solution can avoid the high cost associated with the location and treatment of the potential causes of voids.
