THE boat ramp at Billy Lights Point has been upgraded using new composite technology combining aluminium and polyethylene.
The two pontoons were replaced last week after council investigations found they needed replacing.
The council initially called for tenders for a concrete deck system for its robustness and long life span but decided to accept an alternative tender for an aluminium/composite system, which was a cheaper option with a longer warranty.
Seaslip Pontoons and Products took a week to install the new pontoon system, which uses heavy duty aluminium frames, moulded polyethylene floatation units and a polypropylene deck and promises to out perform the concrete system and be more cost effective.
The council's infrastructure manager Nigel Mezner said he was confident the new cost-effective technology would meet the criteria for life span and performance.
The new pontoons are expected to last for at least 25 years.
The upgrade has been jointly funded by the council and a $80,000 grant from the state government's South Australian boating Facility Advisory Committee.
