Since no soil cover is needed with LiteEarth, it falls within the category of exposed geomembrane covers. However, an important difference is that the LiteEarth is not completely exposed – in the sense that a geomembrane is – but is covered with a synthetic grass. As such, the average lifespan of LiteEarth is much longer than geomembrane-only exposed covers, in which the geomembrane is not protected from the elements of nature.

LiteEarth Performance Highlights

  • Covered or buried geomembranes, such as LiteEarth, are projected to last 7 to 10 times the exposed half-life of the material.
  • LiteEarth’s EPDM liner is expected to perform for more than 250 years.
  • The synthetic grass and woven primary also have been specially treated with enhanced UV stabilizers.
