MATERIAL
Drayvax uses a specially formulated Polypropylene that provides a
high environmental stress crack resistance to alkalines and acids
found in the soil. In addition, Drayvax is made from 100% virgin resin.
Our special extrusion process utilizes low heat and low shear to
prevent heat degradation in the final product. The use of
antioxidants and lubricants further ensure a smooth, superior
quality membrane that outperforms the competition.
