One of the best and easiest materials to finish the waterproofing of a pond is proved to be EPDM. It is less costly and can bear the enormous pressure from the water and also the settlement of the base of the lake. This product is a green and environment friendly too. Befor knowing Trelleborg EPDM, Chamran park had decided to use reinforced concrete as the waterproofing base of the pond. This rigid and costly choice could not give the perfect waterproofing as Trelleborg membrane did. It is now a matter of elegance and beauty to relax in this park. NBN is happy to help in creating the green area with green products. This lake is 2500 sq. m. and is equipped with 1.00 mm Trelleborg EPDM
