Abstract
The present invention relates to a construction method for playground surfacing. The method of the present invention comprises the steps of: a) preparing in situ a mixture comprising 29-70% by weight of cork granules and 30-71% by weight of a polymeric binder, at room temperature; b) pouring the mixture obtained in step a) on at least one surface area; c) compacting said mixture to a thickness in the range of 35-135 mm and to a density in the range of 100-300 kg/m3; and d) curing the compacted mixture from step c).
Claims12
