Seyðisfjörður and Ísafjörður Avalanche Barriers
The project involved the construction of avalanche defences at Seyðisfjörður and Ísafjörður, Iceland. These defences comprised a 20m high catching earth dam, 600m above sea level and breaking earth mounds (or splitters) located in the avalanche path. The earth dams at both sites comprised a lower half constructed from rock fill materials at a slope angle of 34° and a steep reinforced earth upper half with a slope angle in excess of 76°. This upper half was formed using a galvanized steel mesh facing with robust galvanized steel high adherence reinforcing strips. The lightweight components were shipped to Iceland in May 2004. With initial on-site technical assistance provided by RECo, erection of the steep upper sections of the mounds commenced in June 2004. These were successfully completed in October 2004, just before the first snow falls marking the end of the earthwork season. RECo were chosen to design and supply these defences because of proven speed of erection, robustness and successful use on a similar project in Neskaupstaður, Iceland.
