CombiFlex® Projects – Rooftop & High Rise Playgrounds
Project: Children’s play area – rooftop in Hong Kong
Requirement: Drainage and Critical fall height. – reduced surface heat and good drainage.
Solution: CombiFlex® + CombiMesh using wetpour and artificial grass.
CombiFlex® eliminates the use of styrene-butadiene rubber (SBR) as the critical fall height material.
For an equivalent level of critical fall height CombiFlex weighs approximately 12% of the equivalent SBR. Volatile Organic Compound (VOC) binder/adhesive additives are not present in CombiFlex®.
With expected changes in playground standards requiring critical fall height testing annually, CombiFlex® offers a durable long term solution for reliable critical fall height surfacing with a 5 year warranty. CombiFlex® sites have had consistent ASNZ422:2016 critical fall height results without deterioration or erosion.
CombiFlex® is made from a high impact polypropylene copolymer and provides excellent critical fall height in children’s playgrounds. Play areas using just wetpour materials ( ie not using wetpour over CombiFlex® ) have varying reductions of critical fall height over time as the surface compacts and wears down. This results in safety reduction, ongoing maintenance and frequent replacement.
CombiFlex® requires minimal adhesive and is not impacted by the current global adhesive shortage.
