The client reported ongoing leaks from the shower and moisture spreading throughout the entire bathroom. The space was outdated, showed visible water damage, and lacked a floor waste outlet — which is considered best practice, and often required, when a bath is installed in the same room to ensure proper drainage and compliance with AS 3740 waterproofing standards.
Cracked and deteriorating grout between floor and wall tiles
Signs of prolonged water penetration behind tiles
No signs of recent waterproofing or grout maintenance
Our inspection confirmed extensive moisture throughout the bathroom area due to failed waterproofing and poor drainage design. The absence of a waste outlet and the deteriorated waterproofing system meant a full bathroom renovation was required to restore compliance and eliminate ongoing leaks.
Aquatech Grouting completed a full bathroom renovation, including:
Removal of all tiles, fixtures, and wall sheeting
Installation of a compliant floor waste outlet
Re-sheeting with moisture-resistant materials
Full waterproofing to AS 3740 standards
Modern retiling and installation of new fixtures and fittings
Carefully removed all old grout and degraded silicone
Cleaned tile edges using anti-fungal solution to prepare for regrouting
Taped off surrounding surfaces to ensure a clean finish
Installed waterproof grout throughout floor and lower wall joins
Selected a colour-matched grout to blend with existing tile tones
Focused on deep penetration for long-term bonding and water resistance
Applied high-performance neutral-cure silicone to all corners and joints
Ensured flexible sealing to withstand movement in the high-rise building
Applied a clear waterproof membrane coating across the shower floor and corners
Ensured water-tight protection while maintaining original tile appearance

The team at Aquatech were amazing to deal with from start to finish. They completely transformed our old, leaking bathroom into something modern and fresh — and finally fixed the leak that’s been causing us headaches for years. Couldn’t be happier with the result!
