For high water, garages, and basements, leak proof flood barriers are an integral part of keeping property dry. We manufacture inflatable seals for retrofits and pre-existing flood gates. Inflatable seals offer an absolute water barrier when zero leakage is required. They are ideal when flush thresholds are needed such as entry ways to commercial and residential buildings. A dual seal configuration provides an added safety net in the case of any one seal failure. When sensitive equipment and/or documents are located below grade or in a flood prone area, flood barriers and watertight doors are a must.
