Biobarrier Root Control System prevents tree roots from growing in a zone around the fabric. Placed between a tree root and the area to be protected, such as a sidewalk, road, building, golf course green or anywhere that roots can cause damage, Biobarrier creates a barrier that causes roots to grow in another direction. Unlike solid barriers, it does not need to protrude above ground where it could be a tripping hazard and costly liability. Because it is a flexible geotextile fabric, Biobarrier easily fits the contours of any job site and is simple to install.
