Typar SF is a polypropylene filter fabric where the fibres of the fabric are thermally bonded together. Due to the specific nature of the production process, the pores in the geotextile are unevenly distributed, which prevents the plant roots from penetrating the geotextile. Therefore, Typar SF geotextiles have very good weed control properties.
– Water and air permeability
– Separating the subsoil from the structure to be constructed
– Filtration capacity, to prevent soil particles from entering the structure.
– Strengthens the surface
– Prevents the spread of roots
– Prevents soil erosion
