Stabilize the soil base for the entire inflow row of StormChamber® units as well as the adjacent overflow unit with the Woven Stabilization Fabric. This sturdy material is rolled out over the prepared base in the excavated area, and secured to the ground with stakes prior to placement of StormChamber unit(s). Adjoining fabric should overlap by at least two ft. To accommodate the SedimenTrap™ device, cut a hole so the fabric fits snugly under the top corrugation of the pipe.
