Bilgoman Aquatic Centre is located on the corner of Lionel Road and Great Eastern Highway, Darlington. The Centre opens from October to April each year. The facility is set in a bushland environment and includes both a 50-metre heated Olympic Pool and shaded toddler pool with beach entry.

After being in operation for 50 years, Bilgoman Aquatic Centre underwent an entire renovation over the scheduled shut down period. BUSS’ repair works during the centre’s renovation included the removal of tiles and applying new waterproofing membranes. The works were simultaneous with multiple other trades during renovation including major landscaping works. The renovations spanned over six-month renovation period which BUSS mobilised to site frequently.

This renovation and maintenance periods require the complete shutdown of the centre. The scope of the work was inclusive of the replacement of all the failed expansion joints, inside the pool, all its surrounding edges/trim/gutters, the surrounding pavement and the concrete underneath. With respect to the pool remediation, all the waterproofing was replaced including the inside the gutters.  BUSS installed all expansion joint sealing of both the tiles and concrete.

This project highlighted BUSS’ versatility across various type of expansion joint sealing and applications of waterproofing membranes when adapting them to remedial scenarios.
