Flood control

About FLEXIDAMSTM is a leading provider of water inflated flood barriers and cofferdams. It’s deployed as an emergency protection system to reduce the catastrophic effects of flooding on homes and industrial structures in flood prone areas. 

FLEXIDAMs systems are installed faster and require less labor, they are environmentally cleaner than sandbags and its design works as a temporary flood protection in flash flooding events, or when excessive heavy rain overwhelms permanent flood protection, such as levees and dams.
