The BIOBARRIER® Root Control System protects adjacent structures from root damage. Guaranteed protection for 15 years reduces the chance of injury and potential liability, as well as the costs associated with preventative maintenance and damage repair.

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.

While physical barriers alone can create root girdling, BIOBARRIER® stops continued root growth allowing for healthier trees. Placed beside the object to be protected, BIOBARRIER® creates a zone of protection on all sides of the nodules. Roots growing into the zone are redirected while roots outside the zone continue to grow normally; tree health is not impacted since Trifluralin is not systemic.

Since the system includes a standard drainage fabric, BIOBARRIER® allows water, air and nutrients to pass through, not adversely affecting soil hydrology.
