TREMDrain™ DPI is an optional drainage, protection and insulation board designed for use primarily with TREMproof® 260 Spray-Applied Waterproofing Membrane.

Designed for single-sided subsurface vertical drainage applications requiring a typical non-woven filter fabric bonded to a high compressive strength and high flow capacity formed core. TREMDrain 1000 PF incorporates a protective backing film for added membrane protection.

We offer an array of options and newest technologies for maximum protection and expedited schedules. Our knowledgeable, technical sales representative are available to discuss these options and how you can best prevent water intrusion.

Series LFN45B Lead Free* Water Pressure Reducing Valves are used in commercial and residential applications to reduce incoming water pressure to a predetermined level, thereby protecting downstream plumbing system components and reducing water consumption. Designed for easy accessibility and serviceability without removing the valve from the line. For versatility, a variety of end connections are available: threaded, solder, PEX, quick-connect, CPVC, press, or cold expansion PEX (ASTM F1960) with union and double union. Standard pressure setting is 50 psi with an adjustable range of 25 ‒ 75 psi (172 ‒ 517 kPa). For sizes: 1/2 to 1 IN (15 ‒ 25mm).

TREMDrain™ 6600 is a multi-composite prefabricated drainage material and protection board consisting of a formed polypropylene core covered on one side with a high strength, nonwoven needle-punched polypropylene filter fabric that is heat bonded to the core.
