Playground equipment and playground surfacing site drainage

Playground safety surfacing and drainage I just had a customer ask about drainage issues on the playground. The basics: If we dig down, you MUST consider drainage, otherwise you will create swimming pool effect and have puddles, increased break down of your playground engineered wood fiber. If you have unitary surfacing like poured in place or safety tiles, then the subusrface may wash away. However, if you have an above grade solution that tapers slightly you should be fine. Playground wood fiber will still break down, but not as fast. Your sub-surface material will remain in place.
