From France
Maturity stage TRL 9 / CRI 2 - Commercial Trial Small Scale

As climate change worsens, extreme events such as flash floods are on the increase. In 2024, floods affected almost 167 million people worldwide, causing major human, economic and environmental damage. In response, Ausec has developed OBLOC®, a reusable and recyclable flood protection device. It's an ultra-thin bag that inflates in just a few minutes on contact with water, multiplying its volume by 24 to form a watertight, resistant barrier. Lightweight, modular and installable without tools by a single person, OBLOC® adapts to any terrain, reduces intervention costs, avoids the use of sand and minimises waste. OBLOC® is made from superabsorbent polymers that are 100% recycled, making it part of a circular economy approach. This innovative solution represents a concrete, sustainable response to the challenges of climate change, serving both people and the environment.

The Environmental Benefits

  • OBLOC® flood bags allow to reduce the storage volume by 1900% compared to a traditional sandbag. (10 sandbags = 0.36m3, 10 OBLOC® bags = 0.019m3)
  • OBLOC® flood bags are 4 times faster to implement (2 hours for the 10 sandbags (reception, filling and installation), about 30 minutes for the 10 OBLOC® flood bags)
  • OBLOC® bags are 100 times lighter than sandbags
  • Our solution is composed of 87% recycled products (super absorbent polymers not adapted to the hygiene sector), we reuse these products to reduce the waste generated following a flood. The other component is a recyclable polypropylene envelope
  • The use of our products reduces the use of sandbags, CO2 emissions related to sand transportation and damages related to sand extraction

The Financial Benefits

  • Available immediately. 10 OBLOC® bags = 158€ VS 10 sandbags = 198€. No dependence on the town hall. No operating costs (no staff, no workforce, no construction machines, no tools, no transport)
  • In case of flooding at a professional's premises/collectivity, no stoppage of activity. No loss of equipment/products/stock. No loss of customers/sales. The supply chain remains operational
  • Protection of movable property and real estate. No damage, no cost for a flood up to 30/45cm high. Average cost of repairing a property: 11K € (flooring, wall paints, furnitures, home appliance..)
