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.
