A playground play surface that is safe and suitable for use by children consists of a base layer, a fluid permeable base covering layer, a bag layer, a ground particle layer, and a top cover layer. The bag layer consists of a plurality of bags each filled with loose or shredded rubber, and which are aligned side by side forming a single layer of rows and columns. The ground particle layer consists of ground or shredded rubber or tire particles which are secured into a cohesive layer by a binder. A retaining border defines the playground play surface and contains the layers. |
