The non-woven underlayment is not waterproof like PVC pond liners. The underlayment is used as a protective barrier between the waterproof PVC pond liner and sharp rocks, gravel and other debris. Thanks,
Beckett 7202510 (UL612) 6 X 12 ft underlayment is available in some Home Depot stores, HD sku is 576017 or it is available also at HD.com as their on line sku 100001948. Best Regards Kirsi
Yes it will, a pond underlayment will also double has a pool underlayment.
The size needed really depends on the size of your pond. As a minimum you should have enough to fit under the entire length and width of your liner.
Oh! It's weight would be directly proportional to its size. It isn't real weighty, but my project was small. Not as heavy as a cotton towel size for size. More like a sweater would weigh for a piece the size of a towel.
I would NOT use this material for a weed barrier. I do not use weed barrier. It is more hassle than help. Weed and grass seed grows into ANY barrier material and very soon you have a dense layer of weeds and or grass that cannot be dug out with a shovel or any tool. Disaster! This material is not suited for anything other than underlayment for pond liner in my humble opinion.
It's thick enough to be a good pond liner. It is not smooth, it's like an industrial felt.
It is fiberous, but I think it would NOT be a good match for your project. I would not use it for any situation where is is exposed to the elements. It is designed to cushion pond a liner. That is its intended function.
Not at all rubbery or water tight! Felt. Not slippery.
Yes if you wanted to last for more than 20 years this product goes under the pond liner or use it to prevent weeds from growing between your rocks
