Sovereign only uses a Deluxe Hardwood Chip safer surface that has virtually all the dust and fine particles removed. Designed specifically for high movement areas, it also has high fire resistance compliance to BS 4790:1987.
Installation: The Bark Chippings are usually retained using log edging. BS EN 1177 recommends that all loose fill surfacing is laid to a depth of 300mm unless the play equipment has a CFH of undr 600mm, where a depth of 100mm deep surfacing can be used.
Maintenance: Regular checks for foreign objects in the bark. Bark will require regular forking and raking to maintain the required depth.
Critical Fall Height (CFH)
The Critical Fall Height is calculated by the maximum intended height for play from which a child could fall and the ground level. The thickness and area of safer surfacing will depend on the Critical Fall Height.
