Product Details
GS-404 Filter Fabric is a non-woven geotextile allowing drainage of stormwater from the growing media to the water management layer. In addition to retaining the fines of the growing media, it provides excellent laminar flow. GS- 404 maintains separation and provides a cushioning layer between the growing media from the water management layer. The geotextile is produced from a synthetic fabric that is chemically resistant to typical acid and alkali soil conditions and will not degrade over time from nutrients that may wash through the growing media.
Installation
Place GS-404 Filter Fabric over the GS-315 Stormwater Management layer. Overlap all edges 6” with a minimum of 6’ between overlaps. Keep overlaps a minimum of 6’ from all perimeters. Secure filter fabric under any perimeter metal counter flashings. Cut filter fabric around any drainage openings so to not restrict the water flow to the drain. Cut filter fabric around any penetrations in such a manner as to prevent any stone ballast from entering between penetration and insulation.
GS-404 is also used with metal edging to prevent growing media fines from passing through the perforations of the edging.
Packaging
GS-404 Filter Fabric is available in rolls of 12’- 6” (3.8 m) by 360 feet (109.8 m) packaged in bags.
