Water Sucking Concrete?.....Well Almost......

[comp56]

pretty neat concrete top layer to absorb water ......

They did something similar at the Ford Rouge Truck plant in Dearborn MI. The plant also has a living roof to help deal with rain fall on the property. I would like to be able to divert grey water for irrigation to be honest

wow that's freakin cool! I wonder how it will do long term wise.

It's a great idea, but I don't think it works anywhere where there's a frost line below 2-4 inches. There are other options, though.

Florida is perfect for this. I just think it would make a huge sinkhole if there's to much rain..lol

thats relly cool have you ever seen the solar roadways

We actually use something very similar only with asphalt. Makes a great drainage layer.

They have been using it in Sweden for a while apparently so it's good for ice. The water is not trapped under the road it soaks away naturally as if there was no road there. Obviously it is for rain and snow not rivers of water. The idea is to prevent floods forming due to water being trapped on the surface.

I know when we use an open graded pavement you always install some type of subsurface drainage to expedite the flow away from the subgrade.

Our major roads and highways here have that type of asphalt, but to have it in concrete would be nice. The asphalt looks like an open cell foam insulation

Do you know about how thick the layer generally is? We typically place it anywhere from 2.5" - 3" thick. Just curious with your subgrade conditions what you guys use.

That shopping centre is in the UK near Maidenhead , it's not concrete it is asphalt

Someone did say the other day that sections have been replaced already , not sure if that's true or not

On some of the new turnpike construction they have like 6 feet of base, I think there using recycled crushed concrete and the asphalt is like a foot thick. They pave it a few times each time its like 3-4 inches for a regular road its like a foot of base and then like 4 inches of asphalt. But on a driveway to a house the existing earth is compacted and about 3 inches of asphalt. We only have like 4-8 inches of topsoil here and then its solid coral rock if you have to dig a 5 inch hole you better go get the chipping hammer. It sucks the tree roots don't even go down they just stay on the surface

I'm sure it's great for residential use. I'd love to do my whole backyard in that stuff. A massive patio and no major concern for drainage. Wonder how cost effective it is.

I'm sure it could ground smooth and then formed into an awesome shower floor......

Wow that is cool! And during winter it could be used as an ice skating rink.
