Where Does It All Go? Puddles No More

Bizarre ‘thirsty’ concrete sucks up hundreds of gallons of water in less than a minute.

When it rains in Savannah, it usually pours, which leads to flooding. Puddles can stay around for a lengthy period of time.

But a new product could put an end to puddles.

It’s called Topmix Permeable concrete. It’s designed to be a super-absorbent covering that allows water to seep through it rather than sitting on top of it. It’s all to combat flooding.

The new concrete was recently tested in a parking lot. The Topmix concrete ‘drank’ 880 gallons of water in around a minute. Most of the water disappeared almost as soon as it hit the ground.

Some experts say this concrete could make roads safer.


The company, Lafarge Tarmac, says the new concrete could not only help to tackle flash flooding in urban areas but may also help to reduce the heating of tarmac in hot weather.

This whole concept isn’t new. Permeable concrete has been around for nearly 60 years. In the past, however, it’s been used under paving.

The new idea is to use it as a top surface, which would be ideal for parking lots and driveways.

One issue though… the concrete isn’t ideal for colder climates. The water beneath could freeze and cause the surface to buckle and crack.
