Most ski jumps have either a wooden floor or a metal or plastic base. The mats (22x22cm) are attached to the respective floor with appropriate screws, with the plug-in devices of the Watertrax sliding mats pointing to the front and to the right. The mats are first put together in larger areas (approx. 1m x 2m) and then laid one after the other starting from the take-off table and up to the start. Approx. 4 screws per 1 square meter (approx. 20 pcs.) should be used. The steeper it gets, the more screws you use to attach the mats.

So that the jumpers have a better orientation when approaching, colored mats (e.g. red) should be laid out to the right and left of the approach lane. Colored markings should also be installed directly at the edge of the take-off, so that the take-off can also be set better there.

It is advisable to lay a water sprinkler system at the edge of the approach lane, especially for ski jump type 4. Since very high temperatures are generated by the friction of up to 80 km/h, the friction between the ski and the plastic mats is significantly reduced with water. The sprinkler system makes a significant contribution to the long service life of the mats and to protecting the ski surface. It is sufficient if, for example, a water hose is laid on the right edge of the side wall of the inrun from the start to the take-off table. A small nozzle should be screwed into the hose every approx. 3m. The water sprinkler system is an easy installation with a big, positive effect. All major water jumps in the world use the available water from the pool or lake to irrigate the inrun track. A system with approx. 7 bar is sufficient as a pump. The necessary pump capacity depends on the height of the ski jump.
