BATHROOMS & WET AREAS
Internal moisture is a frequent cause of structural degradation in New Zealand homes. Given that bathrooms, laundries, and wet rooms experience daily high humidity and direct water exposure, effective containment is essential.
Proper bathroom waterproofing prevents water from entering porous building materials like framing timber, concrete floor slabs, or GIB Aqualine. Without protection, minor leaks behind walls or under tiles can lead to substantial structural damage, rot, and harmful mould growth over time.
At Sahara Waterproofing, our certified specialists ensure that wet areas remain fully resistant to moisture, safeguarding your home and your family's health.

Critical Protection for Tiled & Wet Room Designs
Contemporary architectural preferences often feature open-plan wet rooms, walk-in showers, and fully tiled bathrooms. While visually appealing, these designs significantly elevate the potential for water migration into adjacent areas if the underlying substrate is inadequately prepared.
​
Our Licensed Building Practitioners (LBPs) configure tailored solutions using premium, industry-approved systems:
​
-
Liquid Waterproofing Membranes: We apply flexible, high-solids liquid membranes from top brands like Sika, Ardex, and Bostik. These systems create a seamless, rubberised barrier across the entire floor and shower alcove, designed to accommodate building movement and prevent cracking.
-
Aqualine GIB and Substrate Sealing: We carefully treat all critical junctions, including wall-to-floor transitions, tap penetrations, and drainage wastes, to ensure underlying wall linings remain dry.
-
Advanced Tile Sealing Prep: Before tile installation, we verify that the membrane application meets the specific technical tolerances required for modern adhesives. This preparation is essential for preventing issues in areas such as acoustic floor systems and underfloor heating mats.
Guaranteed Council Sign-Off (NZBC E3/AS1)
Internal wet area compliance is strictly regulated under the New Zealand Building Code. As certified approved applicators, we provide the necessary documentation, manufacturer warranties, and LBP sign-offs required by local councils for your Code Compliance Certificate (CCC). Every internal wet room we seal is backed by our absolute 10-year workmanship guarantee.
