Davone Constructions – Bermagui

Road Safety Rental NSW have just taken delivery of a new trailer which will increase efficiencies and ease of delivery of our water filled barrier product to sites across NSW.

The trailer, which was purchased from Carbon Equipment was put to the test recently with a delivery of our Big Blockout Barrier to Davone Constructions, who required the barriers to delineate pedestrians from their work zones.

Graham from Davone Constructions said “Road Safety Rental provided a barrier to suit our project, delivered on time and with great communication on collection. No issues all round, will be happy to work with Road Safety Rental again.”
