10 x 15 Feet Pond Liner Underlayment Non Woven Geotextile with 15 U-Pins

Very minimal thickness . This should not be an issue if you have a previous molded liner or SMOOTH excavated EARTH depression. I DOUBLED mine over because of MORE THAN enough material for a 7 x 4 x 2 ft. DEEP pond. Easy too, as felt like, NON-Woven underlayment material molds itself to surrounding pond depression with some effort.

Easy to install, great value, seemed very durable and the size was as advertised. Wasn't as thick as I thought but works for protecting liner. No leaks from liner when using this.

This is incredibly heavy, which can make installation a bear, so strong hands will be needed. With a strong back, install can be pretty easy. This being noted. The quality, value, fit, and functionality of it is great! It is very durable.

This is a very good under liner and the hook are really needed. I put this down by myself, so the hooks made it very easy when I put the liner in place.

Bought this for under our pond liner. Our soil is rocky with many roots so I wanted an extra layer of protection. This is just thick enough and is easy to work with. (Photo is of our pond almost finished.)

worked exactly as advertised, no complaints

Used this under the pond liner for an indoor project pond. High quality! Very pleased!

Seems like a high quality pond liner material that was easy to work with.
