Rubberised Wetpour Safety Surfacing Technical Details

Preparation, base and wearing course

BounceBack Rubberised Wetpour Safety Surfacing has been specifically developed by BounceBack Safety Surfaces Ltd as an impact absorbing system of surfacing primarily for children's playgrounds.

BounceBack is a two layer multi component polyurethane / rubber composite. It is formed in situ by a chemical mixing, wet pouring, levelling, screeding and rolling process to provide a durable safe play surface. The two layers are the base course, which provides impact absorbency, and the wearing course which gives the surface it's strength and durability.

 

Porous Wearing Course

BounceBack wearing course consists of two alternatives:

1. For coloured surfaces the wearing course consists of a 17-20mm thick resin bound formulated E.P.D.M. (Ethylene Propylene Diene Modified) 1-4mm granule. E.P.D.M. synthetic rubber granules are through coloured and are therefore very resistant to wear, weathering, ozone attack and flammability.
2. For black surfaces the wearing course consists of a nominal 20mm thick resin bound recycled E.P.D.M.

Surfaces of 20mm depth are comprised of only a 20mm wearing course.

Base Course

Surfaces greater in depth than 20mm have a base course of rubber which varies in thickness according to the required critical fall height. It is comprised of resin bound recycled black tyre rubber granulate (2mm to 8mm in size). No fillers or bulking out materials are used.
