Dr. Fixit HDPE Prebond S Roller Pre Applied HDPE Waterproofing Membrane

Dr. Fixit Prebond membrane is a preformed HDPE fully bonded membrane that bonds to the wet concrete cast on the membrane. After the membrane bonds with the concrete it forms an integral seal which prevents lateral water migration and makes it unaffected by any substrate settlement below the slabs. Reinforcement can be directly laid on top of the membrane and it does not require screed protection. Dr. Fixit Prebond is a unique HDPE membrane comprising of a virgin HDPE layer and a pressure sensitive adhesive layer which is covered by a weather proof protective layer. The adhesive layer is activated when the concrete is poured on the membrane and it enables the membrane bond to underside of the concrete which prevents the ingress of water into the structure as well as prevents tracking of water between the membrane and the structure and provide a positive side protection against ingress of sub soil water. Dr. Fixit Prebond can be used for horizontal as well as vertical blind side application.Typical Application Basement. Subway and UG metro project. Cut and cover tunnels. Caverns. Other underground civil structures. Features Good bonding with concrete applied on membrane, to protect concrete effectively. Low flatness requirement to substrate; reliable overlapping; fast and easy application. Sound anti-puncture performance. Adaptable to varying surface profile. Resistant to high hydrostatic ground water-pressure. Resistant to acid, alkali, chlorides and sulphate attack. Eco-friendly material. Method of ApplicationDr. Fixit Prebond membranes are supplied in rolls of 2.0 m or 2.4 m wide, with a selvedge of 75 mm on one side to provide self-adhered laps for continuity between rolls. The rolls of Prebond membrane and Prebond Tape are inter-wound with a disposable plastic release liner which must be removed before placing reinforcement and concrete.
