My project with this was lining a French drain trench, 300+ feet, just along the ‘banks’ after the landscaping company neglected to put in any fabric. That was a really bad choice, because the clay just washes into the gravel then, and will clog up the drain ditch in no time.I couldn’t dig out all the gravel and line the whole thing, but it occurred to me that the worst erosion will be along the surface, so I bought this to line the edges. I cut strips of about 12-16 inches in width, and used some ingenuity and tools I had to try to tuck it in between the clay and the gravel. That was a LOT of work, but this fabric held up well.It’s thicker and more substantial, and drains far better, than regular landscape fabric. Geotextile fabric has a different purpose; it’s not something you put down under mulch. Consider it more of a soil retention fabric than a weed blocker; the aggressive Bermuda grass manages to poke through it, though the other weeds that plague my yard don’t seem to.So far I’ve used it to line my French drain as above, and seen how much it reduces the washing of clay into the effluent water; I used it under two retaining walls, and watched delightedly as the rain filtered through the clay soil and then the fabric, running clear as it went to the drain.If you have a project that needs geotextile fabric, this is excellent stuff. I used the 6 oz weight, because I wasn’t sure what I needed and it was right in the middle; it has definitely met expectations and even exceeded them. I bought more from this supplier when I realized how well it worked. Oh, and price wise? Compared to local landscape supply shops, the quality is better and the price is, too. If I need it again, I’ll buy it from this vendor.
