ADVANTAGES (continued)

Bitumen free. Safe for the environment.
High crack bridging capabilities of up to 2mm.
Produced from butyl rubber with both the adhesive bottom layer and the geotextile top layer bonded
during the manufacturing process.
For use in many different types of applications to replace bitumen based waterproof membranes.
Correct 50mm overlap joints are achieved during installation due to orange stripe marker on outside
edge of membrane.
No bentonite present so the product does not expand and break-up in water and/or wash from the
joint, removing the potential of voids between slab/wall and finishes. Butyl rubber gives long-term
durability and integrity to the product and in-turn to the joint and substrate.

AREAS OF APPLICATION

Railway station platform slabs and walls.
Viaducts and Bridges.
Power Stations and Utilities.
Electrical Riser Rooms.
Base slabs, walls and roofs for waterproofing (a topping slab must be applied)
Pipes, manholes and culverts.
Note : The product’s design and performance, its intended use, installation and final confirmation and approval for
use, must be provided by the project’s Design Engineer and Project Manager.
