Secondary Containment Liners-High Density Polyethylene Liners HDPE

The geosynthetic industry has critical needs for its varying applications.

Pond Liner Customer Question- HPDE or LLDPE?

Question:  Do you consider GPS HD 40 mil polyethylene to be a good product to use as
a garden pond liner?  Is it easy to handle and flexible enough to conform to the pond hole?

Answer:  40 mil HDPE is a suitable product for use as a pond liner.  It is one of our two most popular in that thickness range.
  • In most lining applications where there are not contaminated soils or chemicals, LLDPE is the best choice.  It is still very strong, but much easier to work with.  It conforms to surfaces much easier than HD.
  • Pricing is the same, or virtually the same, so neither product has an advantage.
  • We can provide LLDPE in larger sheets, because it can be folded for shipping in many cases.  This often allows a pond liner to be a single sheet with all factory seams.
