Since 1986, Biobarrier® has been the product of choice for re-directing tree and shrub roots from walls, sidewalks, foundations and landscapes. Biobarrier Root Control System is placed in a trench between roots and the area to be protected and is guaranteed for 15 years. “ When we introduced Biobarrier, it was a different kind of product for the market,” said Jerry Dunaway, Biobarrier sales manager. “It still is unlike anything else. We think it is also the most effective and cost-efficient method of inhibiting root growth. For example, it generally costs about $900 to replace 15 linear feet of 4-foot-wide sidewalk. Using Biobarrier along that same stretch of sidewalk costs less than $50.”
