Landmaster PolyPro 55 Woven Landscape Fabric Commercial Grade for Landscape Contractors (Underliner For Landscape Design, Soil Separation, Filtration and Drainage) 4.2 ounce, 8 feet x 250 feet

Strong weed fabric. I use it under bark and decorative rock.

We had high hopes for this weed barrier but our gravel path and rock bed have a Whitetop weed invasion going on underneath (it reproduces from root segments and seeds). Unfortunately, while most of the area has not allowed it through, those weeds have found a way to poke through in a variety of places. I'm not sure if the fabric was walked on and a rock poked a slight hole in it or if the weeds were able to wiggle through it on their own. For the price, it was disappointing.
