WaveSave and its portable rubber dam

As global sea levels rise and extreme weather events become more frequent, the Dutch company WaveSave is addressing flood risks with its portable rubber dam, the SlamDam. Designed for rapid deployment, the barrier can be unfurled along shorelines or riverbanks and filled with water to provide up to 1.3 meters of protection. Beyond flood mitigation, the system offers a unique dual-purpose benefit: the stored water can be used for irrigation during dry seasons, a feature that has already helped farmers in regions like Burundi increase crop yields. While the company faces competition from other mobile barrier manufacturers and challenges regarding initial costs and community ownership, its focus on emergency response in developing nations remains a key differentiator. With a lifespan of over 40 years, the SlamDam provides a scalable, temporary alternative to permanent infrastructure like levees, helping vulnerable communities adapt to the escalating impacts of climate change.
