The Flo-Well® Dry Well Filter Fabric Wrap adds a layer of protection by preventing soil from entering the punched-out weep holes of the Flo-Well Dry Well Side Panels and Cover Kit. The 2 ft. wide X 7 ft. long fabric fits around the entire dry well tank and protects the system in all soil conditions. For best results, use the filter fabric wrap when punching out all 30 1-in. weep holes, which increases the water infiltration rates into surrounding soils. The filter fabric wrap is made of polypropylene geotextile material.
