‘Thirsty’ concrete designed to help prevent flash floods. via dailymail
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.
A video of the material being tested in a car park shows the concrete ‘drinking’ 880 gallons (4,000 litres) of water in around a minute, with most of it disappearing almost as soon as it hits the ground.
