UNDERGUARD Nonwoven Geotextile Underlayment 15 ft Widths Variation

Great product! For pond building, this is now, industry standard for protecting your liner!!!

We have a 20 x 15 pond dug out. We had four people to lay out the underliner and pond liner. We could have done it with one. It was so easy! The liner is thick. It didn't say if the shiny side went up or down, so we put it shiny side down. We didn't even have to pin it - it didn't move after we tucked it. We will see how it holds up, but for now, we are very happy.

I purchased this to use as a weed blocker in my vegetable garden. Today, after leaving the product on my garden year round for 4 years, it is still working very well! This is the greatest week blocker that I've tried. It blocks 100% of the weeds in my vegetable garden, It would not work well for row crops like beans, carrots, radishes etc because cutting a long row will also allow weeds to grow. I use this in the area of my garden where I plant tomatoes, squash, melons and the like. I cut a small "X" then plant the tomatoes or whatever and the fold the "X" back on itself. The weed barrier allows water through without puddling. Fertilizer can be placed on top of the product and the water dissolves the fertilizer, allowing it to pass through the weed barrier to the soil and plant roots. Finally, I can walk on the weed barrier without damaging it and the weed barrier is heavy duty enough that I anticipate using it for several years.

We live in an area which is filled with stone under the ground - so much so farmers would build stone fences on their property boundaries with what came up each spring post-frost heave. With this in mind, I felt I'd use an underlayment to the pond liner material as an extra measure of protection. It's easy to work with and maybe 1/8 inch thick, but the way it's woven makes a good cushion. I tried shocing some pointy shale through it and it would of course deform, but didn't pierce. I wasn't using a whole lot of force, trying to mimic a frost heave. I was building a relatively small Koi pond, and was using native rocks to line the pond. After laying the EPDM liner, I took some of the underlayment and used it as cushion below the pond bottom rocks, to protect the liner just in case, as I was stanging on them while laying stone on the sides. So, good stuff. 4 out of 5 because I have nothing to compare this material to.

Replacing the pond liner was made easy by the product. The old liner didn’t have underpayment, I am not surprised that it didn’t last long. So far the newly installed pond liner is smooth and has no leaks.

Like another customer said... if you order 15x40 you expect a single piece that is 15x40.. not a box with two 15x20 rolls. For my application it will still work, but it is not what was ordered. If I wanted 2 rolls for 15x20, I would have ordered that. As for the quality, it is great stuff. Protects pond liners, functions as a great weed barrier and also wicks moisture if needed.

Exactly what youd expect it to be. Easy to shape,trim and lay.

Easy install considering id never used it before.
