All about EPDM Mulch surface

EPDM Mulch surface – composition

 

EPDM Mulch is made of high-quality EPDM in natural colours. There is no danger of fading, which is the case of coloured mulch from recycled rubber.

 

Basic layer – SBR
The highly elastic lower layer is made of SBR granules (Styrene Butadene Rubber -recycled technical rubber) mixed with special polyurethane binder. Its thickness is 25–80 mm depending on the required fall height, so that it meets the applicable standard criteria. The thicker the layer is the greater fall height it can absorb. One of its great features is the continuous thickness change according to the fall height of different playing equipment without this change being visible.

Upper layer – EPDM Mulch
The extremely durable stepping surface is made of a layer of EPDM Mulch (Ethylen Propylen Diene Monomer), which is synthetic rubber. It is produced in different colours. The EPDM Mulch granules are mixed with special polyurethane binder. This layer is laid as a 20 mm thick monolithic seamless layer.

The surface is laid in two layers on gravel or solid base, same as the SmartSoft surface.  

 

The EPDM layer can also be laid separately without the lower layer. However the base must be solid. (concrete, asphalt, etc.) But such surface is not suitable under playground equipment with certified impact. Its advantage is its lower price.
