ThirstyConcrete

Topmix Permeable is a fast draining concrete pavement solution that rapidly directs stormwater off streets, parking surfaces, driveways and walkways.
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.

Thanks Bruce!
