Can I purchase and install this product myself:
HDPE requires trained technicians and special equipment. CLI's crews are certified and trained in the installation techniques.

Can HDPE be used in potable water applications?
HDPE can be obtained with National Sanitation Foundation (NSF) certification for suitability for contact with potable per NSF-61 Standard." Be sure to check availability before specifying HDPE in this application.

  
   
  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 resistant to rodent attack?
 HDPE is very rigid and tough and therefore difficult for rodents to bite. It is inert and does not contain potential nutrients such as plasticizers or reinforcing yarns that may be attractive to 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.

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.
