Testimonials

VicRoads Innovations & Initiatives Bulletin

“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.”

Adrian McKenzie, AMACK Petroleum and Plumbing Contractor

“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.”

Adrian McKenzie, AMACK Petroleum and Plumbing Contractor

Paul Bergman -Maintenance Coordinator / Electrical Assets Brisbane 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”

Paul Bergman -Maintenance Coordinator / Electrical Assets Brisbane City Council

Neil Lofts, Main Sewers Technical Officer, Barwon Water

“If someone has a similar requirement, I think Terra Firma’s ThruBeam pit lids are a great choice. I looked around at a lot of other lids, as well, but I thought that Terra Firma’s pit lids, for our purpose, were the best choice”.

Neil Lofts, Main Sewers Technical Officer, Barwon Water
