CANLON brand Forfens Pre-applied Waterproofing Membrane is composed of white polymer sheet (HDPE or TPO), pressure sensitive adhesive, and weather resistant coating layer. This unique coating layer is a developed organic chemical, which can react with the post-cast concrete as it cures so as to form an effective bonding between the membrane and the concrete. Meanwhile, the coating layer is anti-stick as well as effectively protects the pressure sensitive adhesive layer.
Effective connections on selvedge overlaps can also be achieved in harsh jobsite conditions(such as rain, water, low temperature, etc.).The installation of membrane adopts the pre-applied method, which can realize full bonding with the post-cast concrete and prevent water migration.
