Waterproofing Bridges

Bridge Systems Diagram


Dermaflex 50250 is a 5 mm thick membrane incorporating a heavy duty polyester reinforcement which makes it particularly suitable for waterproofing bridge decks, car parks and similar applications.

The Dermaflex membrane (D) is placed directly on the concrete deck (B) and should be fully torched to the deck, in which case the concrete should be painted with bitumen primer (C). Particular attention should be paid to expansion joint and other detailing and it is strongly recommended that the contractor agree with the engineer as to how these should be treated.

In the case of pre-fabricated joints it is also advisable to consult with the manufacturer.
