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
