10 Climate Change Technology Companies to Watch: WaveSave and its Portable Rubber Dam

WaveSave is highlighted as one of MIT Technology Review’s 10 climate change technology companies to keep an eye on in 2026. Exclusive for subscribers.

With sea levels on the rise and the threat of flooding increasing, WaveSave has introduced an innovative solution: a portable rubber dam that can be quickly deployed when flooding occurs.

Simply lay the dam along a riverbank or shoreline, fill it with water until it inflates to a height of up to 1.3 meters, providing protection for nearby structures from rising water levels.
