The Villa Root Barrier panel is made of high density, recycled polyethylene with a male and female connector for easy installation. These panels can be configured into the desired length needed or for a specific size tree that is being planted. Be sure to have the ½” deflection ribs, which are spaced every 6 inches facing the tree roots. Villa has been manufacturing root barriers for over 20 years and our products have been used in many commercial, industrial and residential projects throughout the United States. If you’re looking for quality & price you have come to the right place.
