Fosroc Proofex GP

Proofex GP is a cold applied self-adhesive sheet membrane
comprising of a polymer modified bitumen layer internally
reinforced , bonded on to an outer surface of polyethylene
film.
The polymer bitumen adhesive layer is protected on the
underside by a silicone release paper which is removed just
prior to the application of Proofex GP to the tack coat primed
substrate.
The applied membrane is then immediately protected from
UV light and from mechanical damage during subsequent
back filling by the application of Protection Board, or a sand/
cement screed.
