CPSX™ Carpark Expansion Joint

The CPSX™ carpark expansion joint system has revolutionised carpark expansion joint installation for both retrofit and new construction offering a sustainable, water tight carpark expansion joint system that is installed flush in the expansion joint gap. Departing from traditional metal armoured car park expansion joints that are surface mounted to the carpark deck with fixings. With the added benefit of UV stabilisers, CPSX™ is perfect for installation in rooftop carparks and outdoor areas.

CPSX™ is made up of two layers. The bottom layer, a specialty flexible closed cell foam water seal that is adhered to the expansion joint gap with an Australian made epoxy adhesive designed to keep water and debris from exiting the expansion joint gap. Grooves along the sides of the seal allow further bond strength to the application’s surface. The upper layer consists of rubber strands made from recycled truck tyres in Australia, bound together with an Australian made elastomeric binder that allows the rubber to expand and contract providing multi-directional movement.

The rubber strand layer not only protects the water seal from being punctured by sharp objects, but also stiffens the surface of the seal increasing point loading. Allowing pedestrians and trolleys to traverse safely over the expansion joint gap, avoiding heeled shoes from ‘sinking’ into the seal. The system is free of any metal cover plates, metal armour or fixings (that can shear off due to thermal movement) and is installed flush with the expansion joint gap.
