A New Flood Protection System
We have designed the worlds first affordable flood protection system for private homes.
Flood protection isn't just about saving homes — it's also a powerful tool for cutting CO2
Turning flood defenses into climate solutions
Roisser helps reduce CO₂ emissions by preventing floods and avoiding energy-intensive repairs, protects homeowners and insurers from rising premiums, and delivers massive societal value - saving billions in damage claims with standard installations costing less than 100,000 DKK.
Over the next 100 years, the total expected damage to homes, holiday homes, commercial buildings, transport, agriculture and tourism will amount to around DKK 406 billion, converted to present value. The costs are distributed with an estimated DKK 157 billion for torrential rain and approximately DKK 249 billion for storm surges.
406 billion annually
1/8 Europeans
Already today, one in eight Europeans lives in areas potentially prone to river floods and around 30% of people in southern Europe face permanent water stress. Climate change will further increase exposure of people to weather extremes with serious health consequences.
€1 trillion
The economic damage from coastal flooding in Europe could reach almost €1 trillion per year by 2100 without new investment in adaptation to climate change.
