ACO Polycrete  offers POWERDRAIN trench drains, a range of high performance drains designed for heavy duty applications.  

Perth Airport, like any major airport plays an integral role in the region’s economic activity. Its contribution to the economy is heavily contingent on its capacity to operate efficiently.  

The booming WA economy has contributed to a significant increase in domestic passenger traffic impacting on the ability of the airport’s infrastructure to cope, especially with regard to domestic apron space.  

This has driven Westralia Airports Corporation (WAC), the operators of Perth’s airport to invest over $AU100 million yearly on aeronautical infrastructure including the extension of taxiways, the construction of new aerobridges as well as the upgrade of baggage screening and terminals. The apron extension is designed to facilitate the movement of aircraft.  

During construction, engineers specified over 200 metres of ACO’s POWERDRAIN S300K (300mm wide) trench drains to be installed across the hangers and apron areas.  

Constant movement of very heavy loadings on airport hardstand areas imposes severe stresses on the pavements making the POWERDRAIN trench drains an ideal solution due to its heavy duty construction.  

These heavy duty trenches comprise of interlocking precast channels made from polymer concrete, a durable resin composite with excellent flow characteristics. The system’s ductile iron grates meet class G900kN (AS3996).  

For this application, the channels were assembled in a sloped configuration to allow for the efficient removal of liquid from the apron’s expansive level pavements.  

During the design phase, the project’s engineers concluded that ACO’s Australian-made off-the-shelf precast drain systems were considerably cheaper than traditional grate and frame in-situ drainage systems.
