New Munot Bridge with innovative UHFB surfacing
The northern Munot Bridge is the main access to the historic fortress in Schaffhausen and is used daily by locals, tourists and for the delivery of goods at events. The existing bridge, built in 1961, was in need of renovation. Roland Strebel, Head of UHFB at Implenia, and construction manager Patrick Burkhardt agree: "Thanks to the use of ultra-high-performance fiber-reinforced concrete (UHFB) for the flooring, it was possible to meet the visual requirement of the monument protection authorities that the color of the new bridge should match the masonry of the fortress."
The benefits of UHFB - ultra-high-performance fiber building material
Switzerland's transport infrastructure is under increasing strain and the life cycle of bridges and roads is decreasing. This is why Implenia, together with partners, has developed the ultra-high performance fiber construction material (UHFB). The construction material has the highest mechanical strength and durability as well as a high deformation capacity. It is also resistant to acid sulphate, frost and vapor. It is also characterized by its resistance to carbonation and mechanical abrasion. UHFB is an alternative to a total replacement of the object. Coupled with its durability, UHFB can reduce road closures and congestion times, which offers enormous added value in view of the increasing volume of traffic.
