Artificial Turf Filling
So called "infill”, which is artificial grass infill in the form of rubber granules, is introduced between synthetic grass fibers for the purpose of their stabilization and provision of suitable playing comfort. Basic structural elements on which artificial grass carpet is installed include:
Infill – the filling has two layers: sand and rubber granules. Quartz sand ensures drainage and stabilization of synthetic grass, while rubber granules ensure good surface flexibility and safe playing Additionally, both layers "care" for horizontal positioning of artificial grass fibers and prevent their relocation, kneading and deformation.
Base – it is usually built with coarse aggregate such as break stone, for example. Also, the base may be asphalt or concrete
Substrate – the most common materials used to build the substrate is stone, gravel. Main purpose of this layer is to stabilize the whole structure and to ensure its permeability, i.e. suitable water removal.
