Drayflow Lite

MATERIAL

Drayvax uses a specially formulated High Density Polyethylene that
provides a high environmental stress crack resistance to alkalines
and acids found in the soil. 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.

The Drayvax Lite drainage board finished product has a 0.031’
(8 mm) dimple height, providing a drainage capacity of 12 gal/min/ft
of width and a compressive strength of 6,700lbs/sq ft. Polyethylene is
highly resistant to chemical interaction and has a life expectancy of up to 50 years when properly installed in
accordance with the manufacturer’s instruction
