Prebond S HDPE Sheet

Dr. Fixit Prebond E is a preformed and pre-applied 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 E is a unique HDPE membrane comprising of a 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 E can be used for horizontal as well as vertical blind side application.

Features & Benefits

Excellent Adhesion with concrete placed over the membrane, to protect the structure effectively, from the positive side.
Low flatness requirement to substrate; reliable overlapping; fast and easy application.
Lesser joints and overlaps, due to large roll widths.
Adaptable to varying surface profile of the substrate.
Resistant to high hydrostatic ground water-pressure.
Resistant to aggressive ground water conditions.
Eco-friendly material.
