Calculated critical fall height value: 3,4 m* 

*

Approximate measurement obtained in the test under natural conditions, on a grassy substrate (natural grass) with a moisture content of approximately 23%. It should also be noted that the behaviour of different substrate materials can vary depending on the prevailing weather conditions, which can also significantly affect the CFH result. For a proper result, it is suggested to carry out an individual measurement on site, ,after installation of the grass mat.
