DISCUSS A PROJECT

Bridge over Floyd River in
Sheldon, IA USA

In 2017, Cramer & Associates Inc. of Grimes, IA was awarded the main contract to rehabilitate the deck of Floyd River Bridge as part of a large bridge rehabilitation package. WALO Iowa LLC was chosen as a sub-contractor for the UHPC overlay project, due to our expert know-how and experience with the material. WALO has successfully completed a variety of UHPC applications in Europe, most significantly the 2.3-mile-long Chillon Viaducts, alongside Lake Geneva in Switzerland. Recognized by the American Concrete Institute (ACI), the Chillon Viaduct rehabilitation was the first ever project to use a machine to install a UHPC layer on bridge decks.

The 9,020 sq. ft UHPC overlay job was completed in less than ten workdays, by our Swiss-American construction team and with support from Cramer & Associates Inc. and LafargeHolcim North America.

One lane of the bridge remained open for public at all times for the course of the project to minimize traffic disruption to the traveling public.
