A concrete that sucks water!

Concrete is rarely the most fascinating of subjects, but a strange thirsty version of the material has turned it into something rather compelling. Topmix Permeable concrete is designed to be a super-absorbent surface covering that allows water to seep through it rather than sitting on top in an attempt to combat flooding.

While helping to prevent surface water flooding during storms, the concrete could also help to make roads paths safer by preventing puddles that could pose a risk, according to Tarmac, which has developed the concrete. It works by having a permeable layer of concrete on top that allows water to drain through large pebbles into a loose base of rubble beneath.

Drainage channels incorporated into the rubble can help to increase the amount of water it can cope with. A statement by the company said it could not only help to tackle flash flooding in urban areas but may also help to reduce the heating of tarmac in hot weather. They said: Permeable concrete allows surface water to freely drain through the wearing surface to the underlying ground with the ability to act as a reservoir during periods of high downfall.

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.
