Good thing a reporter from radio was there with a microphone.

"This is the sound of concrete absorbing water. Trust me."

A zimą? Nie zamarznie i nie rozsadzi?

What about freeze winter? Won't the iced water crack it?

This is previous concrete! it does not absorb water. The concrete simply does not have small aggregate, so the water can pass through the larger aggregate. It also can retain the same amount of PSI rating needed, Its self healing, and can drop a temperature difference of 10-15 degrees because of its porous holes. This is also considered to be LEED certified for any LEED recommendations/credentials

No. The water is not absorbed by the concrete. The concrete is porous which means that the water will move through the concrete and into the soil (the concrete is specially made so that water does not cling to the aggregate on top). Believe it or not this concrete cracks less than normal concrete. It also will never have black ice because water does not sit on top of it.
