Runway rubber removal

Rubber removal on concrete or asphalt runways using up to 720 kW ultra high pressure water blasting technology with an integrated extraction by suction system. Dependant on the construction and condition of the runway, the right pressure is chosen in order to save the micro and macro texture of the surface. A significant advantage is gained by using the multijet system, which employs a combination of very little water (1L/nozzle/minute) and the ultra high pressure (2.500bar/36.250psi). Removal width is 1.500 / 2.500 mm.
Debris and dirty water resulting from rubber removal operation are deposited into a tank integrated into the unit, with a separate tank for fresh water storage. Such arrangements make the unit self contained and allow maximum utilization of valuable time on the runway.

No chemicals are used in the cleaning process. Debris (rubber sludge) and water is disposed into a standard container (skip). Simple decanting, in some cases speeded up by a non toxic biodegradable flocculant, will separate rubber sludge from a water phase that can be disposed into the waste water system. It makes the cleaning process the most environmentally friendly solution.

In case of emergency landings, the unit will leave the runway immediately, leaving a clean and almost dry surface behind for air traffic!

Paint marking removal

The removal of paint, thermoplastic and structural marks on concrete and asphalt surfaces is carried out in our company by uing 2500 bar high pressure water technology.
Pressure and angular velocity of the rotating nozzle beam will be adjusted depending on the nature of the surface. Water and abrasives will be simultaneously absorbed and stored in the vehicle for pre-sedimentation.
Area performance depends on thickness, type of marker and the nature on the ground. Normally, it is between 75m2 and 300m2/h. With working widths between 220mm and 1500mm, both lines and surface markers are efficiently removed.

Apron cleaning

At an apron cleaning by HPW technology, the surface is freed of oil, kerosene, grease and curing remains.
Joints, existing markings and lights are not damaged.
