December and January was all about delivering three new Courts for the Mount Compass Netball Club.
The old courts had cracking and water pooling in areas creating an unsafe surface for players.
Demolition of not one but two courts ( one on top of the other) in most areas uncovered some history.
New electrical runs for existing and future light poles trenched in and wired up thanks to Laser Electrical.
Sub base was then graded up ready for a 150mm layer of PM1 rubble which was laser graded with fall for water runoff and compacted.
Pole inserts concreted in and finished off with a new surface thanks to Elite Ashphalt.👌
Line marking by Ace Line Marking.
