Underlayment Geo-textile

  • Protect your liner by installing a barrier fabric underneath it, to protect sharp rocks and other objects from puncturing the liner.
  • This soft, non-woven geotextile made from polypropylene will last 20+ years under your liner.
  • Comes in a 15' width, and can be cut to any length.

Note: The underlay fabric will wick water from your pond to the ground if you are installing it OVER your liner and if it is allowed to touch the surrounding soil.  Always ensure that the edges of the geotextile do not come in contact with the surrounding soil when you are using it under this circumstance.
