Portadam

Welcome to Portadam, an MES Company. For over 50 years, Portadam has delivered engineered, modular water management solutions to clients across the U.S. and around the world. Our flexible systems are used for temporary cofferdams, flood protection, and fluid storage. When deployed as a temporary cofferdam, our system allows contractors to perform in-water work in dry conditions. Units are available in heights up to 12 ft and can be quickly combined to match varying subsurface elevations and contours and minimize overall rental costs. Our proprietary Portadam® system is one of the world’s most advanced portable water diversion solutions. Since 1974, we’ve supported thousands of projects, from restoring landmarks like the Washington Monument and Maryland’s historic Burnside Bridge to protecting billions of dollars in corporate and public assets, including real estate, utilities, and transportation. Trusted by the U.S. Army Corps of Engineers, FEMA, and the Bureau of Land Management, we tailor every solution to the unique needs of each site.
