Watching This Concrete Slurp Up 1,000 Gallons Of Water In A Minute Is Sorcery

If you want to see something cool, look no further… this new type of concrete from the UK building materials company Tarmac instantly soaks nearly 1,000 gallons of water per minute. This stuff is like magic! Not to mention, it looks completely satisfying.


It’s called Tarmac Topmix Permeable, and it’s basically a super-porous concrete pavement that’s designed to remove storm and floodwater from parking lots, driveways, sidewalks, and other surfaces.

Once the water enters the permeable concrete top layer, it then passes through pebbles beneath to become groundwater in the soil. The concrete can drain about 1,000 gallons of water in roughly a minute, and according to Tarmac, the concrete could be installed anywhere to mitigate flood risk.


You probably have a few questions like… What about freezing temperatures? Or what about dirt blocking the permeability over time? Basically, the water would freeze on top of the surface and not into the layer itself, and as far as dirt clogging…

Well, the permeability rate of the material is so great, there would have to be an unrealistic amount of dirt applied to the surface for the pavement to cease functioning effectively. It can even function effectively when blocked by up to 95%.




This is completely mesmerizing to watch. No more puddles, or flooding! Make sure to drop us a comment below, and don’t forget to give this a share on Facebook. (h/t Gizmodo)
