Operational difficulties posed by the previously existing concrete cover slabs led to an essential replacement program programme being mandated. The end user had recently moved into the facility and established that an alternative covering solution would be needed to optimize optimise future operations due to specialist personnel and machinery being required for removal and replacement of concrete slabs and other issues including:

• Previously existing D400 concrete covers were extremely heavy and cracked in some areas (as pictured stacked, awaiting disposal)
• Central and offset service access ports required in order to allow easy access to services without the need to completely remove covers

A smooth finish was also required (no tread pattern).
