The Journal has learnt that a number of visitors slipped over on the floor surface in the pool zone just two days after the Casey RACE officially opened on June 13.

While the recycled rubber granules that cover the pool floors have been used successfully overseas, Casey RACE is the first Australian site to use the eco-friendly technology.

Although no one suffered more than minor grazing in the spills, the pool was closed last Monday and Tuesday with the exception of scheduled swim classes.

Rubber matting has been laid on the floor until a permanent solution is found. It is understood Casey's position is that the builder must foot the resurfacing bill.

When the Journal was tipped off about the problem late last month, Casey provided a written statement at the time advising: "The builder has confirmed the floor surface material meet the requirements of the Australian Standards for slip resistance".

In the latest Casey response last Friday, infrastructure services director Ray Butler said in a written statement: "Following the opening and use of the Casey RACE on Saturday, June 13, an issue arose with the surface of parts of the pool deck.

"The builders have been requested to undertake additional surfacing of some sections of the aquatic area and further tests are being conducted."

As an interim measure, rubber floor mats would be used and a revised aquatic timetable implemented "to best accommodate the needs of all aquatic users".

Cr Kevin Bradford, whose Mayfield Ward includes Cranbourne, said he was extremely confident the floor issue would be settled in due course and "we will have a tremendous facility to be proud of for many years".

Casey residents have turned out in droves to enjoy the state-of-the-art facility. Some fun-seekers were turned away towards the end of the afternoon session of the free family fun day on Sunday week when full capacity was reached.

A total of more than 2500 people attended both sessions of the free event.
