“Terra Firma pit lids substitute a poorly performing heavy product with a cost effective, strong, lightweight alternative. Their installation throughout the M80 upgrade has minimised the manual handling risk to workers by weighing ¼ of a concrete lid and through its easy to use lifting key that minimising the stress on the body whilst opening.”

VicRoads Innovations & Initiatives Bulletin

“The OH&S benefit for our maintenance workers, and the reduction in maintenance costs demonstrated during the initial trial installation has now led to the Council rolling out a budgeted annual pit lid replacement using lightweight composite lids.”

Engineer, Launceston City Council

“Frankston City Council have faith in the product and over the past 17 years have experienced the return on investment firsthand – in terms of economic benefits and time efficiency, as well as improvements to OH&S”

“We have seen Terra Firma continue to improve their lids from the word go – they have a lid for all situations, in classes B, C, D and E. They are well suited for practicality, as well as aesthetically with a selection of different colours enabling us to match the lid to the colour of the paving around it.”

Maintenance Planning & Contracts Coordinator, Frankston City Council

“The installation of the Bianco Precast encased Terra Firma lightweight pit lids at these locations have already paid forthemselves. Prior to these installations concrete pit lids were being replaced at these locations every month, sometimes twice a month. The Council has now begun specifying Terra Firma pit lids for capital works programs and new subdivisions.”

Civil & Maintenance Coordinator, City of Norwood Payneham & St Peters

“After discovering Terra Firma composite fibreglass lids, Unley City Council were able to reduce the number of workers required for installation and maintenance of their drain covers, as well as reducing the risk of injury to their workers”

Project Manager Capital Works, Unley City Council

“I can see a definite use for these lids as a replacement where needed – for pits around the City and Valley where the sweepers are causing deformation of the existing plastic lids. They would also be useful in other high traffic / vehicle path areas around existing intersections.”

Maintenance Coordinator, Brisbane City Council

“Don’t worry, with the Terra Firma D400 pit lids, we can open the lid, inspect the pit and have it closed before the customer has finished paying for their petrol.”

Contractor, AMACK Petroleum and Plumbing
