Parking Saas Fee
Deformation of the concrete rolling surface, structural deficit in terms of puncture resistance, sloping terrain (5% gradient) ... the equation to be solved for the repair of the covered car park at the Saas-Fee ski resort was arduous. Ductal® took up the challenge and developed an innovative product meeting all these constraints.
Commodore Barry Bridge
The Commodore Barry Bridge spans over the Delaware River from Chester PA to Bridgeport NJ. Originally constructed in 1969 and named after the Revolutionary War Hero from Philadelphia John Barry. This bridge is a cantilever truss bridge which was commonly built during those times.
The Chillon Viaducts have been reinforced by an Overlay of Ductal® UHPC. Thanks to its mechanical characteristics and its durability properties, Ductal® was the only material able to provide an efficient retrofitting preserving the bearing capacity of the bridge, a lower maintenance cost and a quick retro commissioning of an important axis of the Swiss highway network. The two Chillon Viaducts are among the most spectacular infrastructure works of the Swiss highway network. Ductal® was prescribed for the reinforcement of the two decks (2.2 km long by 12 m wide each). The implementation of thin layer of Ductal® (4 cm thick) with rebars, allowed the strengthening of the bridge decks for shear loads, bending, and fatigue while ensuring the waterproofing of the surface.
