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.
