Portland Rain and 22 Stories

Portland, Oregon’s rainy climate can be a dicey proposition during construction, yet an innovative barrier system answered the call when it came to preventing weather delays that could impact project scheduling. A city known for constant rains, dramatic shifts in climate throughout the year and perpetual moisture, Portland, Oregon provides unique challenges for any construction project.
