Waterproofing and Roofing Systems
RamDrain DD 050 HS is a two-part prefabricated geocomposite drain consisting of a formed polystyrene core that is covered on one side with woven monofilament filter fabric. This fabric allows water to pass into the drain core while restricting the movement of soil particles which might clog the core, allowing the water to flow to designated drainage exits.
RamDrain DD 050 HS with ½" height can move more drainage water per foot width than a layer of stone which is 1' wide and 180" high.
RamDrain DD 050 HS is designed for horizontal applications.
RamDrain EN 36R is an entangled net prefabricated composite drain 0.45-inches thick, “zig-zag" geometric patterned core, drainage mat with a layer of non-woven geotextile on both front and back of the product. RamDrain EN 36R has a 3-inch (76.2 mm) fabric flange beyond the core to provide overlaps with adjacent drainage courses.
RamDrain Dimple Drain (DD) 050 is a high-performance drainage sheet engineered to relieve hydrostatic pressure by creating a channel for liquid water.
RamDrain DD 050 is a two-layer superior flow-rate system. The first layer is constructed of high strength, cuspate (dimpled) polymetric sheet designed to provide superior compressive strength. Adhered to the high strength, cuspated polymer base is a nonwoven filter fabric. The filter fabric is designed to promote high water flow while not allowing dirt and silt to penetrate the drainage channel.
RamDrain DD 025 HS is a two-layer extremely high compression strength system. The first layer is constructed of high strength, cuspate (dimpled) polymeric sheet designed to provide superior compressive strength. Adhered to the high strength, cuspated polymer base is a nonwoven filter fabric. The non-woven spun-bonded filter fabric is designed to promote high water flow while not allowing dirt and silt to penetrate the drainage channel.

RamDrain 2451 is a 1″ perforated composite polymeric drainage with fabric on both sides.
RamDrain 1241 is a 1/2″ perforated composite polymeric drainage with fabric on both sides.
Roofscape® Extensive Media is a planting medium for extensive vegetative Greenroof-Roofscapes® systems with a separate drain layer, designed to retain stormwater and to promote long lasting vigorous plant growth, and which meets the requirements described in ASTM E2777-14 Standard Guide for Vegetative (Green) Roof Systems (see Technical Data Sheet for more info).
