  How long will an EPDM liner last?  
  What does chemical resistance mean?  
     
 

Can EPDM be installed even if the temperature is below freezing:
EPDM is not affected by low temperature extremes, even if exposed. It remains flexible and can be installed and seamed at below freezing temperatures (low temp resistance to -49° F/ 45° C).

  
   
 

Can decorative rocks and boulders be placed over the liner?
At 45 mil thickness, EPDM has a working strain to over 500% and conforms readily to overburden materials and installation over rough sustrates without puncture.

  
     
  Can I cover it with dirt if I want to?
Yes. The rubber surface texture provides excellent friction resistance to prevent soil sliding on the surface.		  
   
 

How long will an EPDM liner last?
This synthetic rubber material is designed for decades of outdoor exposure to the elements and inert to the effects of buried environmental microorganisms.

 
   
  What does chemical resistance mean?
An EPDM liner will survive exposure to a large variety of chemicals, even though the chemical could have some effects on the liner, without causing the liner to fail. If you have a specific concern, give us a call at 800-524-8672.
