A playing surface, such as a synthetic grass turf includes a base structure having a layer of fine particulates, preferably a layer of sand stabilized by fibers for supporting the playing surface lying thereupon. A method of providing an adequate resiliency property for impact absorption to the base structure comprises a step of embedding a plurality of flexible and resilient granules into the layer of fine particulates. The flexible and resilient granules are spaced-apart clusters in the layer of the fine particulates. This method is advantageously applicable to various types of playing fields in both new construction and retrofitting tasks.
