DuO Bridges & Tunnels

DuO Bridges & Tunnels is the Duo membrane used for infrastructure works. The membrane has the same composition as Duo High Tech but comes with an extra strong composite reinforcement in the middle. It has a special granular protection to resist site-traffic.

Concrete and asphalt layers can be directly applied on top of the membrane without the need of an additional protection layer. It is extremely strong and is used where there are extra high demands on strong waterproofing membranes such as is the case for open cut tunnels, bridges and car parking decks.
