Why do safety mats and granulate rubber mats feature a structured underside with raised elements such as studs and supports instead of a smooth surface?
The structured underside of safety mats and granulate rubber mats is a key construction element that fulfils various functions depending on the application.
Water Drainage
When used outdoors, rainwater permeates the porous rubber plates. It can either soak into the ground or, in cases of an impermeable substrate, flow along the “drainage channels” formed by the raised studs and supports, following the slope.
Reduction of Tension Forces
The design of the underside helps to dissipate tensions within the rubber mat caused by external factors such as temperature and humidity fluctuations, thereby improving the stability of the surface.
Vibration and Noise Damping
The reduced contact area enhances vibration damping and contributes to effective sound insulation, which is particularly beneficial in applications such as terraces and balconies.
Weight Reduction
Finally, the reduced use of material due to the non-solid construction leads to a lower overall weight of the mat or plate, simplifying transport and installation.
