Goodbye, Potholes! “Thirsty” Concrete Sucks Up Hundreds of Gallons of Water in Mere Seconds

Topmix Permeable is a new type of super-absorbent concrete designed to soak up nearly 900 gallons of water in only one minute! Streets paved with this special, ‘thirsty’ concrete will not flood during storms, and they’ll also remain free of puddles and potholes.

Lafarge Tarmac, the company that developed the 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.
