Add extra protection and peace of mind to your pond, your investment.

  • Increases pond liner life and is quick and easy to install.
  • Protects from sharp objects and prevents ground under liner from over-stretching. 
  • Made from 100% polypropylene non-woven material, will not mildew and is resistant to damage from insects and rodents. 
  • Material weight: 7oz

 

*Width is always 15ft wide. Pieces can be overlapped and come cut to help with placing. 

How to Determine the Size Underlayment You Should Buy:

1.) Determine the total sq ft of your pond liner: Example 20'x30' = 600 sq ft

2.) Divide the total sq ft of your liner by 15 (this is the width of the rolls they come on): Example 600 sq ft / 15 = 40 

Example: You would need to purchase a 15'x40' underlayment

The underlayment is impressive

So I bought the pond liner because they recommended it- didn't know if it would be worth it or not but wasn't a terrible amount of money. Boy it was an impressive product. It felt almost as thick as craft store felt, but made from some type of polypropylene or similar. I first tried to cut it with a brand new utility knife and couldn't get the blade in (yay, though it led to a brief panic), oddly cut perfectly fine with scissors.

It's working great!

We are using the underlayment and liner to line a concrete watering trough that we haven't been able to repair. So far, the trough is full and holding water. We are very pleased. Thanks for the pre-purchase advice and prompt shipping.

Just like they said

Of course it's heavy, so hard to move n such, but it was folded nice as was the underlayment, the whole process went smooth with 1 adult and 2 kids helping spread it out !
