Weed barrier fabric is an effective and environmentally friendly way to control weeds in your garden or landscaping. This heavy-duty weed barrier fabric is made from 3.2 oz/sq. yd PP material that is UV treated to minimize degradation from UV exposure. The close woven fabric provides strong tensile strength, making it durable and trampling resistant. The black fabric blocks sunlight to prevent photosynthesis and suppress weed growth. The weed barrier fabric is UV resistant and will not fade or degrade over time. It is also non-toxic and odor-free, making it safe for use around children and pets.
