Municipal Sales uses a specialty in house designed root control application system that actually removes the debris from the roots prior to the application of its product. The real secret is a specially designed sewer nozzle that allows the hose to be inserted in a line while flushing the debris from the roots and on the return trip the herbicide is released with foam filling the pipe.
Why use foam filling? That’s simple, roots grow from 9:00am to 3:00 pm in a pipe so by foam filling the pipe this insures complete contact with the roots. This foam filling process also penetrates crack and joints as well as incoming laterals to completely penetrate all sewer surfaces.
