HG 3510 - Extensive Flow Drain
Our Extensive Flow Drain is a “zig-zag” geometric patterned core drainage mat designed to eliminate hydrostatic pressure in plaza deck, roof garden, & planter assemblies.
Specific to this product, it:
is produced from an extruded polymer matrix of tangled monofilaments, which are heat-welded at the junctions to form a resilient structure
utilizes a non-woven geotextile filter fabric heat- laminated on one side to prevent soil or sand particles from entering the airspace, keeping the drainage plane clear
provides no source for the promotion of mold, mildew, or bacteria and resists most known corrosive chemicals, including solvents
is highly flexible; conforms to irregular surfaces and corners
is acceptable in both horizontal and vertical applications
