For root control, we use a product called RootX, a foaming root-control chemical for residential and municipal sewer lines, storm pipes and septic systems. The patented RootX formula foams on contact with water to reach the top of the pipe where 90% of the roots are. Degreasing agents strip away grime so the RootX herbicide can penetrate the roots, killing them on contact. RootX sticks to the pipe walls, preventing re-growth for up to three years. Dead roots decay over time, restoring pipes to their full capacity.
