Watch the video to learn how to determine the coefficient of friction step by step on a flat roof and integrate it into the Base On planning software.
The structural integrity of a penetration-free mounting system is achieved by the dead weight, module weight and additional ballast. Prerequisites for a proper assembly include suitable roof construction, as well as sufficient loadbearing reserves of the building.
A significance influence on the structural integrity of this type of construction is the interaction between roof covering and the building protection mat, and between mounting system and building protection mat, which are defined by the coefficient of friction. The coefficient of friction is incorporated in the static calculation 1:1. It is therefore necessary to determine the friction coefficients on site and verify them.
The coefficient of friction, also called friction values (formula symbol μ), is a dimensionless measure of the frictional force in relation to the pressure force between two objects.
Coefficient of friction µ = F : G
For testing, you need the coefficient of friction case, which you can purchase from K2. This tool can be used to determine the value on bitumen, foil, concrete, gravel and green roofs.
Please enter the determined value in the "Roof" area in Base On. Please pay attention to the notes on page 4 in the coefficients of friction protocol.
