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

Sometimes we meet people in the construction industry that doubt the quality of waterproof concrete. To them, and all others, we will say;

Our concrete experts with more than 50 years experience only used 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 cement, 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.”
