Waterproof Decking Installed on Drawbridge


Bascule Style Bridge (Drawbridge) in Adelaide, South Australia, Replaces Timber Walking Surface with Waterproof Aluminium Decking by NexGEN Decking.”

DryDeck Aluminium Decking by NexGEN Decking is a lightweight and waterproof decking product which made it the perfect solution to The Birkenhead Bridge’s timber concerns.

The Birkenhead Bridge in Adelaide, South Australia, was built in 1940 to allow river traffic to proceed further upstream. The original hinge section substructure of The Birkenhead Bridge was constructed mainly with timber to reduce weight and to assist engine when opening and closing.

74 years later it was clear a new solution was needed for the bridge when the timber actually started becoming heavier when wet and suffered from long-term corrosion. DryDeck Aluminium Decking by NexGEN Decking offered a lightweight and waterproof decking answer to the bridge’s timber problems.

“Due to the road surface being difficult to seal, the timber substructure was always becoming saturated which caused extra weight and long term deterioration,” said Andy Holland, of NexGEN Decking. “They [the engineers] needed a lightweight, waterproof decking surface to be installed on the hinged part of the bridge.”

Manufactured with exacting precision, DryDeck’s interlocking lightweight boards securely and easily locks into place. The engineering of DryDeck’s aluminium decking boards result in a completely watertight surface that is made to last.

As well as needing improvements made to the bridge’s road surface, the bridge also needed to incorporate a dual use path for walkers and bikers using the bridge. “With the promotion of bicycle use, it became obvious that a dual use path was needed, to handle the increased traffic, this is where DryDeck was viewed as a solution,” said Holland.

DryDeck was designed and engineered for high traffic use in the most demanding applications. It is also naturally resistant to the deteriorating effects of direct sunlight and water. DryDeck is extremely resistant to staining, impervious to insects and won’t splinter, decay, or rot.

DryDeck is ideal for new construction or remodelling of existing outdoor structures, such as, The Birkenhead Bridge. DryDeck provides a lifetime of low-maintenance benefits while creating a gapless, skid free, single layer watertight surface. Its easy installation adds both value and space in a single system.
