Applications

Wet Pour Rubber Crumb play area

Elevated play areas

The Fall Safe variant adds an impact-absorbing base layer beneath the wet pour rubber crumb. Its thickness is specified to suit the critical fall height of the play equipment, creating a surface designed for the particular play area rather than a single standard build-up.
Wet Pour Rubber Crumb roof terrace

Communal roof terraces and podiums

The Standard variant provides a porous, slip-resistant surface for shared outdoor spaces where a fall-safe layer is not required. The raised structure helps accommodate the levels and build-up of an elevated terrace.
Wet Pour Rubber Crumb mixed surfaces

Terraces with mixed surfaces

Boundary profiles create clean transitions between wet pour rubber crumb and other finishes. The system can be coordinated with RYNO paving and planter systems as part of a wider terrace design.
