The cleaning of large-scale constructions,
such as facades, traffic areas or
airport runways, is an essential preposition
for successful maintenance and
for guaranteed safe operation.
WOMA's high-pressure waterjet
systems are successfully used in these
areas since decades. The technique is
suitable for the following applications:
|
 |
Cleaning of brick, concrete, plaster, plastics, metal and rock surfaces. |
|
Removal of paint and worn protective coatings. |
|
Removal of rubber from airport runways. |
|
Removal of road markings. |
|
Cleaning and decontamination of industrial floors. |
|
Roughening of smooth asphalt and concrete surfaces. |
|
Internal and external cleaning of large storage tanks. |
|
Emission-free surface treatment. |
|
Cleaning of facades, pile plankings, etc. |
|
Removal of asphalt, bitumen and concrete. |
Friction values for runways before and after waterjet treatment (Measurement: SAAB Surface Friction Tester)
|
Why High-Pressure Water Jets? |
|
Very wide range of tools and accessories. |
|
Small tool dimensions and low weight. |
|
Small reaction forces; cleaning tools can be run automatically or remotely controlled. |
|
Minimum vibrations and body sound. |
|
Avoidance of any gas and slag. |
|
Very sensitive and selective removal of coatings, impurities and deposits without damaging the base materials. |
|
No influence on the mechanical and structural properties of the base materials. |
|
Applications possible during active production. |
|
Avoidance of chemical or abrasive additives; reduced disposal amount. |
|
High cleaning quality and high degree of decontamination. |
|
Possibility of emission-free treatment due to special tools. |
The Material Range |
|
Using high-pressure water jets, the
following materials can reliably and
environmentally-friendly be removed:
Bitumen, coating systems, paint
systems and plasters, protective coatings,
deposits, linings, oils, parting
agents, resin, rubber, rust, soil, soot,
stripings.

The Technique |
|
WOMA offers stationary and mobile
high- and ultra-high pressure water
jetting systems with operating pressures
up to 3,000 bar and water flow
rates up to 900 l/min, consisting of
electric or combustion drive, highpressure
plunger pump, guiding and
control devices, water tools, and highpressure
accessory. If required, vacuuming
devices and water treatment
systems are available.
The systems
can be run mechanically or automatically.
For the rubber removal from airport
runways, Runway-Cleaners have
been developed. The high-pressure
hot water systems Ecotherm® with an
operating pressure of 800 bar and a
water temperature of 98º C are ideally
suited for cleaning oily and sooty surfaces.
The special high-pressure program for
surface treatment also includes the
following components:
