Duke’s utilizes Razorooter™, a herbicide-laden, thick foam the consistency of heavy shaving cream. Since effectively killing roots in sewer systems requires access to the entire line, Duke’s crews insert a hose from manhole to manhole. The hose releases and sprays the foam in all directions, allowing it to adhere to roots and penetrate through wye connections to kill roots even in lateral lines. The entire system is treated as foam compresses against pipe surfaces and penetrates cracks, joints and connecting sewers. Roots are killed on contact inside and outside the pipe walls, decay naturally and slough away, with regrowth delayed for two to three years. Trees and other above ground vegetation are not harmed.
The Duke’s Guarantee
Duke’s guarantees to kill all the roots in every sewer we treat and to eliminate main line stoppages caused by live tree roots. If live roots are found in a sewer within six months after the application, or if a treated sewer plugs up and floods due to tree roots during the guaranteed period, we will re-treat that section, at our expense, or remit to the customer 100% of the payment we received to treat that section of sewer. Any section of sanitary sewer we treat will not plug up and flood due to tree root obstructions for a period of two years. The guarantee period begins on the date of treatment and ends two years after the date of treatment. When we perform a repeat application within six months of the expiration of the previous guarantee, the guarantee is extended for an additional three years.
“Duke’s solves maintenance problems. I have worked with them directly for many years on several projects, and I’ve seen the exceptional results firsthand. I have personally entered manholes where we had up to 80% blockage caused by large root masses. After the Duke’s application, I re-entered one year later, and the roots were completely decayed. I’m so confident in Duke’s products and services that I refer them directly to my municipal clients.”
“The comprehensive MOM program, which includes a sizable root control effort, is a prime example of a success story that can be shared with other similar communities. It documents capacity assurance results and reductions in SSOs, which was our primary goal, without the high cost of implementing traditional I&I reduction efforts. We now have a good, solid foundation, fewer environmental impacts, and a process to continually get to the cause — grease and roots — instead of our previous reactionary approach to cleaning when the stoppages occurred. We have made great strides.”
