RootX is a simple, cost-effective way to kill pipeline roots in sewer lines, storm pipes, and septic systems. The material foams on contact with water; the foam fills the pipe to reach the top surface, where 90% of the roots live. Degreasing agents strip away grease and grime so the herbicide can penetrate the roots, killing the root tissue on contact. Further, the material is formulated to promote bacterial growth to speed the decay and natural removal of roots, and to inhibit regrowth.
