Dr. Fixit PreBondCONCRETE INTEGRATED HDPE MEMBRANE
FOR WATERPROOFING
HDPE self adhesive membrane that bonds well to the wet concrete
A unique membrane comprising of HDPE layer and a pressure sensitive adhesive layer
Description
Dr. Fixit PreBond is a unique HDPE membrane comprising of an 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 surface and it bonds to the concrete which will prevent the ingress of water around the structure.
Areas of Application
• Basement • Subway • Tunnel • Cave • Other underground public constructions.
Features and benefits
}} Good bonding with concrete when applied and protects concrete effectively
}} Low flatness requirement to substrate; reliable overlapping; mechanical fixing, easy application
}} Sound anti-puncture performance
}} Adaptable to settlement and distortion in subgrades
}} Weather-resisting and partially anti-UV
}} Resistance to mild acids and alkalis
}} Eco-friendly material
Packaging
2.4 m x 20 m
Method of Application
Application on Raft
}} Surface preparation
}} Pre-Bond can be applied at temperatures of –4ºC or above. During cold or damp conditions, the selvedge and
tape adhesive can be gently warmed using a hot air gun or similar to remove moisture or condensation and
improve initial adhesion.
}} Place the HDPE membrane film side to the substrate with adhesive/coated side up facing towards the concrete
to be poured. End laps should be staggered to avoid a buildup of layers. Leave plastic release liner in position
until overlap procedure is completed (where applicable).
Application on Retaining Wall
}} Mechanically fasten the membrane vertically using fixings (i.e. fasteners) appropriate to the substrate with the
adhesive/coated side facing towards the concrete pour. The membrane may be installed in any convenient
length. Secure the top of the membrane using a batten such as a termination bar or fixing 50 mm below
the top edge.
Internal and external corners should be formed as shown in the diagrams returning the membrane a minimum of
100 mm and sealing with Pre-Bond Tape. Ensure that the apex of the corner is covered and sealed with tape and
roll firmly.
