Engineered Wood Fiber can move around and get displaced after consistent play. It is important to make sure that the material is spread evenly and at the proper depths throughout the entire play area.

Because EWF is a loose-fill material, there is potential for foreign objects to get mixed in with the surfacing. EWF requires regular inspection and removal of foreign objects from the playground surface to ensure that the surfaces remains safe for play.

Engineered Wood Fiber will compact and decompose over time due to use and weathering. Make sure that the mulch surface is periodically checked to ensure that it is not below the recommended depth. If it is, additional material should be added.
