Non-woven fabrics provide an effective, long-term solution to weed suppression. Made frompolyester or polypropylene, the material is non-porous, so it restricts oxygen and resists water penetration. These two factors reduce weed growth but they can harm the root systems of trees, shrubs and plants. Non-woven materials can be used to stabilize soil behind retaining walls or as under layments for paver patios or crushed stone walkways. They block weeds, help prevent paving materials from sinking into the soil and discourage ants and other insects from burrowing underneath.
