29'' x 21' Biobarrier
Biobarrier Root Control Barrier - protects your hardscapes and landscapes from damage caused by tree and shrub root intrusion. Manufacturer guarantees it for 15 years.
Biobarrier works invisibly to deflect roots. Its nodules slowly release trifluralin, preventing root tip cell division, which is the method by which roots grow. A small amount of trifluralin is constantly released and as it biodegrades , is continuously replaced, ensuring the effectiveness and long life of the herbicide zone.
