Dyrhoff’s engineers are currently overseeing the installation of rubber dams on two projects in the Americas. Both projects are replacements of Bridgestone rubber dams which were originally installed in the 1980s and 1990s. In USA, Rob Pace is advising on the installation of a seven-span hydropower rubber dam on the Missouri River in Montana. In Guatemala, Kenan Tezcan and Martin Bilafer are advising on the installation of a Sumitomo-manufactured rubber sheet at a hydro plant in Zunil Province. This dam has been subject to high levels of sedimentation and will incorporate Dyrhoff’s innovative replaceable cover sheet technology to protect against abrasion (Patent Pending No. GB1400246).
