Sealing conditions in Kawana Waters
Kawana Waters began as Kawana Island, with construction starting in 1960, and was renamed in 1968. The canal-estate suburbs around it, along with newer Birtinya and Parrearra, sit largely on reclaimed land. Commonly the ground is flat with a shallow water table, and the medical precinct and commercial centres add heavy, constant traffic. Commercial car park sealing here has to cope with that.
For owners this means water problems rather than wear problems. Surfaces pond, edges soften and potholes come back after every patch. Commercial entries face braking and turning loads on top of that. In our experience, most repeat failures trace to drainage or a saturated base, not to the seal itself.
It matters because this work only pays off if the base stays dry. A reseal on a drained, properly prepared base can last 7-15 years, while a seal over standing water may fail in a fraction of that. Doing the drainage first is the cheaper path over time.
Our approach is to inspect, mark the wet spots, and agree the fix before any binder is sprayed. Then we prime new or reworked bases, spray hot binder and cover it with aggregate. Binder needs dry weather, so we watch the forecast, and busy sites are staged in sections.
