Wakaflex is the practical approved universal product for professional abutments at chimneys, walls and other rising structures, obtainable in a variety of colours.

Wakaflex® is a rollable multi-layer laminate, consisting of Polyisobuthylene (PIB) with an aluminium grid and butyl strips at the edges. The self-welding effect is an outstanding advantage which saves up to 30% time during installation compared with other products.

Wakaflex® should be used in conjunction with a connection strip which assists in keeping the upper edge secure to the abutment and thereby ensuring protection from water ingress.
