The layer construction must take into account wind drift/erosion protection. Depending on the load capacity of the substructure, Optigreen “Low Density” or “High Density” Substrates can be used. Weight specifcations refer to saturated conditions; dry weight is approx. 60 – 70 % of the saturated weight. Wind drift/erosion protection must be observed.
