Our line of environmental friendly and innovative waterproof and insulating concrete bring advantages into all concrete construction in general.

We use our own developed recipe and modern technology to improved the success they had in eg. Petra Jordan for about 2.200 years ago with waterproof concrete. 

“They created underground cisterns that were lined with waterproof concrete, to prevent the water from seeping into the earth. The cisterns were very well-constructed, and several of them are still in use to this day.”
