Bathroom Waterproofing & Remedial Waterproofing in Sydney – Protect Your Home the Right Way
Why Waterproofing Is Essential in Every Sydney Home
Sydney’s climate — with its mix of humidity, heavy rainfall, and coastal exposure — makes waterproofing a critical part of home construction and renovation. Without it, you risk:
Mould and mildew
Structural damage
Rotting timber or plaster
Expensive bathroom repairs
That’s why professional bathroom waterproofing and remedial waterproofing are not optional — they’re a must for long-term protection.
Bathroom Waterproofing – Your First Line of Defence
Bathroom waterproofing protects wet areas like showers, floors, and walls from water penetration. It involves applying a waterproof membrane that acts as a barrier between water and the building structure.
At Hills Waterproofing, our process includes:
Surface preparation and priming
Application of compliant waterproofing membrane
Sealing joints and drainage points
Ensuring full compliance with AS 3740 (Australian Standards)
✅ We use premium Australian-made products like Sikaflex and Enviro Systems for durability and reliability.
Remedial Waterproofing – Fixing What Others Failed to Do Right
If your home is showing signs of water damage, you may need remedial waterproofing. This service targets failed or poorly installed waterproofing systems — especially common in older homes or rushed renovations.
Our remedial waterproofing services include:
Leak detection and damage assessment
Removal of damaged membranes
Moisture drying and structural repairs
Application of new compliant waterproofing system
🔧 Why it matters: Remedial waterproofing is faster and more affordable than full renovation, and prevents further damage from occurring.
