How It Works
Duke’s exclusive
process.
Duke’s certified applicators use specialized
equipment to fill the affected sewer pipe with thick herbicidal
foam. Foam with a thick, shaving cream consistency like Duke’s
is essential to adhere to roots and travel up the laterals.
Duke's exclusive dense foam also packs more active chemicals
in the spaces between the bubbles and has a longer retention
time.
After inserting the hose from manhole to manhole,
the foam is released, compressing against pipe surfaces, penetrating
cracks, joints, and connecting sewers. Roots are killed on
contact, decay naturally and slough off. Duke’s applications
prevent root re-growth for 3-5 years.
Duke’s uses
the most effective chemicals and methods.
Duke’s continually researches the most effective products
available. Razorooter II® is the only diquat-based herbicide
registered by the U.S. Environmental Protection Agency (EPA)
for controlling nuisance tree roots in sanitary sewer line
collection systems and received a classification of “evidence
of non-carcinogenicity for humans” (USEPA Diquat R.E.D.
Facts, July 1995).
Duke’s is able to provide safety for applicators,
workers downstream, homeowners, and treatment plants. Roots
are killed on contact inside and outside pipe walls, and the
foam penetrates through wye connections to kill roots in lateral
lines. Trees and other above ground vegetation are not harmed.
In addition, no jet trucks or other potentially damaging equipment
are used.
