Definition - What does Hydro-Jetting mean?
Hydro-jetting is the process of using highly pressurized water to loosen debris, clear blockages, and clean existing pipes before a repair treatment is applied. Hydro-jetting involves the use of compressors and pressure hoses with cleaning nozzles to feed through the pipe for cleaning. In trenchless construction, the hydro-jetting process is completed prior to installing cured-in-place pipe material or relining damages pipes.
Trenchlesspedia explains Hydro-Jetting
Hydro-jetting is a hazardous operation as the water stream is pressurised to 4,000 psi in order to provide the force required to rid the pipes of product, debris and rust. Extreme safety precautions must be taken when participating in this process. It is vital that a thorough cleaning process is completed prior to repairs being made as materials used in the repair operation will adhere to dirt, rust, or other physical contaminants present which can compromise the repair.
