Bathroom Waterproofing

Why Is Waterproofing So Important in New Properties?

Water damage is one of the costliest issues property owners face and it's often preventable. Inadequate or poorly installed waterproofing can result in serious long-term problems such as:

• Mould and mildew growth
• Structural deterioration
• Rotting timbers
• Costly and recurring repairs

Australian Standards (AS 3740: Waterproofing of Domestic Wet Areas) lay out strict waterproofing requirements for key areas like bathrooms, laundries, and wet areas. Yet despite these regulations, waterproofing mistakes are still common in new construction.

Common Causes of Waterproofing Defects

Many property owners assume that waterproofing is a builder’s responsibility. While that’s technically true, builders often subcontract waterproofing to third-party contractors, which can lead to inconsistencies or rushed jobs. These defects often remain hidden until it's too late months or even years after the build is complete.

Some of the most common waterproofing issues include:

• Substandard preparation
• Poor membrane installation
• Inadequate sealing in wet areas
• Faulty drainage systems
• Insufficient fall

Why You Need an Independent Building Consultant for Waterproofing Inspections

Hiring an independent building consultant is one of the smartest decisions you can make during or after construction. At Red Dog Property Inspections, we specialize in waterproofing and moisture control inspections for new property, giving you peace of mind before handover or early occupancy.

Don't Let Water Damage Ruin Your Investment

Waterproofing issues don’t always show up immediately. Many defects remain invisible until major damage occurs, often outside your builder’s warranty period. By then, the cost of repair can easily run into the tens of thousands.
