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.
