Surface preparation

High-pressure water jetting is recommended, and even specified in some cases, in almost all relevant construction regulations and guidelines as a method for preparation of substrates. In addition to technical benefits, environmental compatibility and economic efficiency speak in favour of using WOMA high-pressure water jet technology.

Hard working - Versatile and flexible usage.

WOMA high-pressure water jet technology enables the precise metering of force to be applied on the material to be processed. For this, pressure and flow rate are controlled in relation to the object. For special applications such as removing thermoelastic coatings, hot water solutions are available.

WOMA high pressure water jet technology is the optimum solution for many applications in the construction industry:

Treatment of substrates with high-pressure water jetting takes advantage of the principle of selective damage behaviour to various materials. It does not matter whether different concrete strengths or a substrate with costing is being worked on. In any event, the force of the high-pressure water jet on the flexible material has a destructive effect, while the harder material remains completely undamaged. Because of this, the secondary damage often seen with other methods, e.g. loosening of internal components or damage to reinforcing bars, does not take place.

WOMA high pressure water jetting causes, when applied correctly, no changes to the mechanical properties or structure in the edge zones of processed components and materials. The result is a perfectly clean and rough surface as long-term load-bearing basis for a new coating and the guarantee of high pull-off strength.
