EPDM geomembrane liner is an unreinforced, highly flexible material that is incredibly durable. With a soft rubber-like feel, similar to an inner tube, this UV-stable product has excellent tensile strength, is highly resistant to punctures, ozone, and weathering. EPDM geomembrane liners are an excellent choice for exposed applications or as water barriers within earthed dams. Its easy installation also makes it a favorite for backyard landscapers. EPDM has excellent elongation characteristics and conforms well to irregularities in the subgrade.
