Guru G-Flex Uncoupling Membrane, 323 Sq Ft Roll


G-Flex by Guru is a polyethylene membrane with a raised circular pattern. The back of the membrane is covered by a geotextile fiber. Acts as a waterproofing membrane, compensates vapor pressure if moisture appear on the substrate and a uncoupling membrane on critical substrates.

G-FLEX is an uncoupling membrane made by creating a free air nodules shape right after our extrusion module. It has a homogenous plastic layer and one fleece layer beneath. Its nodules has been crafted to reduce the use of thin-set. The result of installing it under floor coverings, ceramic tiles and natural stone is a great improvement to the installation life both indoors and outdoors.

It can be used as a bathroom waterproofing membrane too, when installed according to the waterproofing method. It is so because of its plastic layer.

This uncoupling membrane stands out for the efficiency obtained when it is installed on risk of cracking substrates with a possibility of movements or with vapor stresses due to residual humidity.

G-FLEX membrane waterproofs all possible surfaces regardless of whether it is old or new, humid or dry, and regardless of whether it is cracked in plain or may be subject to dimensional movements.
This happens thanks to the compensation produced by the uncoupling sheet for hygrometric contraction and thermal expansion.

It should be noted that it does not have any problem with the joining of the joints, since it is not entirely necessary to respect the joints that occur in the supports when we carry out large installations.
