This is semi interesting.

But where does the water actually go? The base courses must have to be quite a bit different from normal.

It has to go somewhere, Ok on a sloping site, but could let water come up from underneath on a flat site.

It's an old technology that's been improved, check the comments here:

No good for concrete tanks LOL.

Could be a great thing with careful base preparation, perhaps a layer of shingle over a membrane so the water drains though the concrete and then runs off to one side and a linking drain via the shingle layer. The water must be taken away and not be allowed to "sit" in the concrete or a frost could seriously damage the concrete.

My question would be how long until dirt and debris that would be carried in by the water builds up enough to clog it? Be like a big sponge catching all the crap going through it, except you can't squeeze it out to clean it.

Mmmmm very cool idea for specific locations.
Still a little confused by the video which mentions it being Asphalt AND Concrete.

Pretty sure this is very similar to the same Asphalt that we see appearing on many roads that need more noise & water control such as busy intersections.
