BioBarrier® root control system is a Typar® geotextile which incorporates trifluralin nodules that prevent root growth by deflecting the roots away and acts as a barrier. A small amount of the trifluralin herbicide is released and as it biodegrades, it is continually replaced ensuring a long life and effectiveness of the herbicide zone.

Typar Biobarrier® root control system offers guaranteed protection against root damage to landscapes and hardscapes. Architects, contractors, urban foresters, building managers and city public works departments benefit from the prevention of root damage through reduced maintenance costs and the elimination of liability issues.

Biobarrier® root barrier is an innovative, effective root barrier that is suitable for nearly every situation / application as it inhibits tree root growth and shrub and weed root growth into irrigation systems, parking lots, sidewalks, green roof applications, building foundations, levees, tennis courts, golf courses and landscaped areas. Typar BioBarrier® works invisibly to deflect roots by slowly releasing trifluralin from the geotextiles nodules to prevent root tip cell division (the method by which roots grow). The roots do not penetrate any further towards the geotextile barrier and will grow in another direction away from the area protected by Biobarrier®.

BioBarrier® is easy to install by fitting it in a narrow trench where the root protection is required. As the trifluralin nodules are bonded to the Typar® geotextile fabric, it allows water, air and nutrients to pass through, not adversely affecting soil hydrology. Tree health is not impacted since trifluralin is not systemic.
