BBA Approved GP TITAN Flex is a polyethylene membrane specifically designed, manufactured and tested to  perform as a barrier against methane, carbon dioxide, radon, ground gases, VOCs, air, moisture and hydrocarbons. In applications where a dual waterproofing system is required, GP TITAN can be used as a fully bonded Type A barrier alongside either an integrated Type B structural barrier or an internal Type C Cavity Drain Membrane System.

When compared to the vast majority of existing Type A waterproofing membranes, GP TITAN is on average, TWO THOUSAND times better performing as a ground gas barrier, as well as providing superior durability and longevity.


GP TITAN Flex can be installed using either the appropriate TITAN Tape or welded joints (please speak to your Wykamol Technical Manager as this will be dependent on the application method).
