Can HDPE be used in potable water applications?
HDPE is rated as suitable for potable water applications through the National Sanitation Foundation, Standard 54.

  
   
  Are there any limits on project size?
No, projects could vary from small (a few hundred square feet) to millions of feet of geomembrane.		  
   
 

Is HDPE immune to rodent attack?
 Yes, HDPE contains no plasticizers or scrim source proteins which would attract critters.

  
   
 

What does chemical resistance mean?
HDPE membranes are used as an impermeable flexible barrier to prevent contamination of the soil and groundwater by the chemical extraction solutions used in mining, as well as recapturing and recycling of solutions.

If you have a specific concern, give us a call at 800-524-8672.

  
     
 

Why does it have wrinkles?
Because of the thermal expansion/ contraction due to variance in temperature will cause the liner to grow or shrink (approx. 2% over 100°F) causing a slightly "relaxed" wrinkling.

It is advised to avoid wrinkling in any seam area.
