Thirsty concrete absorbs 4,000 litres of water in 60 seconds

Thirsty concrete is a new type of super-absorbent concrete designed to soak up nearly 4000 liters of water in just a 60 seconds! Lafarge Tarmac is the company who have developed this technology, uses relatively large pebbles to make a permeable top layer of concrete. Water that hits the surface will seep through the matrix into a loose base of rubble underneath. Drainage channels are worked into the rubble, to help increase the amount of water absorbed.

The company said Topmix Permeable can help tackle flash flooding in urban areas, and also help reduce heating of tarmac in hot weather. During periods of heavy rain, the underlying ground can also act as a reservoir. “During these periods, this characteristic can aid in delaying the discharge of surface water into water courses or drainage systems reducing the risk of overwhelming systems and causing flash flooding,” they revealed. “Water stored within the system evaporates creating a cooling effect reducing surface temperatures.”

Benefits of Thirsty concrete

  • Efficient stormwater management
  • Environmental management
  • Reduced costs
  • Ease of placement
  • Aesthetic appeal

Applications of Thirst Concrete

  • Sports Pitches
  • Sub-base
  • Cycle paths
  • Parking lots
  • Driveways
  • Sidewalks

The only downside, it isn’t suitable to use in areas with extremely low temperatures, though, because the entire system may destroy when the water beneath it freezes.
