Reinforced Chemical Resistant Membrane
MRC1500
WHAT IS MRC 1500?MRC1500 is a synthetic reinforced membrane based on a polyester textile which is molecularly coated with a high quality resin. The polyester tissue gives high mechanical properties to the membrane while the coating provides the waterproofing and chemical resistance. The tissue consists of polyester threads. The polyester tissue is firstly impregnated with a resin to avoid all wicking effects; then the tissues are coated with a resin. This resin is an “interethylene polymer resin” which provides the membrane with a high resistance against petroleum products and other chemicals. MRC1500 membrane is very flexible and has a high dimensional stability.
SUGGESTED SPECIFICATION Keytec MRC1500 is a synthetic reinforced membrane bored on a polyester textile which is molecularly coated with a high quality resin. It has a mass per unit area of 1092gm² and a thickness of 0.91mm.

Specifying Keytec SUDS systems provides the following benefits:
• Significantly reduced flooding risk and compliance with Building Regs and CfSH/BREEAM by either: - Recharging of local groundwater (infiltration/soakaway application). - Controlling and reducing volume release of stormwater into watercourses (or existing sewer systems) by attenuation.• Aerobic purification to improve quality of surface water run-off.• Sustainable, cost effective management of the water environment.
Keytec Geomembranes can supply and install these systems with appropriate impermeable membrane according to the soil conditions and geotextile as a protection or for a soakaway.
