For many years, "POLTIM" company uses the hydrodynamic method to remove gum surface from runways at Polish airports. The surface which is grinded that way gives a better traction and contributes to a safer landing and taking off of the plane.
This type of service is carried out mainly at airports due to the necessity of useage of water without abrasive or sand. Because of that, as in the case of removing rubber, the entire process takes place relatively quickly without disrupting the current functioning of the airport.
Hydrodynamic method (550 - 750 bars) uses rotating jets in which the direction of water flow outlet allows to simultaneous cleaning the inner walls of the tube/pipes and sliding movement of the nozzle into the tube.
Working principle of the nozzle in the tubes
