A & H Tiling Group’s Expert Bathroom Waterproofing

What is bathroom waterproofing, and why is it essential for coastal homes?

Bathroom waterproofing involves applying impermeable membranes and sealants to wet areas—like showers and tiled floors—to prevent water ingress and structural damage. For coastal homes in Maroubra, Randwick and the Eastern Suburbs, high humidity, salt spray and UV exposure accelerate membrane wear and corrosion. Proper waterproofing safeguards against leaks, mould growth and costly repairs, ensuring your renovation investment remains protected.

Which areas does A & H Tiling Group service for bathroom waterproofing?

We cover the entire Sydney Eastern Suburbs, including Maroubra, Randwick, Bondi, Clovelly, Bronte and surrounding suburbs. Our local teams offer rapid response times and 24/7 emergency support, ensuring any leaks or membrane failures are addressed immediately. No matter where you are in the region, you’ll receive consistent quality, transparent quotes and manufacturer-backed warranties.

What waterproofing standards and certifications do you comply with?

All our installers hold a Licensed Building Practitioner (LBP) endorsement for waterproofing under NSW Fair Trading, guaranteeing compliance with the Home Building Act. We strictly follow Australian Standard AS 3740 for wet-area waterproofing and maintain full public liability and professional indemnity insurance. This certification ensures your project meets legal requirements and qualifies for structural warranties and insurance coverage.

How do I choose between cementitious and liquid waterproofing membranes?

Cementitious membranes are trowel-applied, quick to install under tiles and ideal for flat floor areas, but offer limited flexibility. Liquid membranes, by contrast, self-level and adapt to uneven substrates and complex junctions, with superior crack-bridging performance. Our experts assess your bathroom’s moisture load, substrate condition and expected movement to recommend the optimal membrane system.

Are eco-friendly waterproofing options available?

Yes. We offer low-VOC, water-based acrylic coatings, bio-based polyurethane blends and cementitious systems reinforced with recycled aggregates. These materials reduce indoor air pollutants, lower your home’s embodied carbon footprint and align with BASIX sustainability requirements. Choosing green waterproofing supports healthier living spaces and long-term environmental stewardship.

How long does waterproofing take, and when can I proceed with tiling?

Cure times vary by membrane type: liquid systems often cure within 4–6 hours, while cementitious membranes may require 24–48 hours before tiling. Our team factors in local climate conditions—humidity and temperature—to ensure proper curing. We issue a full compliance report once the membrane has cured, clearing the way for tilers to commence work.

Do you handle council approvals and compliance reporting?

Absolutely. A & H Tiling Group manages all aspects of council documentation, from pre-work inspections to final compliance certification. Our project managers coordinate directly with local authorities to secure permits and sign-offs under relevant heritage or strata overlays. This turnkey approach streamlines your renovation and eliminates compliance headaches.

What warranties and guarantees back your waterproofing services?

We provide manufacturer-backed warranties on all membrane systems—ranging from 10 to 20 years depending on the product—and our own workmanship guarantee. In the rare event of a failure, our 24/7 emergency response team will assess and rectify the issue promptly. You’ll receive a detailed warranty document outlining coverage terms, exclusions and maintenance requirements.

What questions should I ask before hiring a waterproofing specialist?

Ask for the contractor’s WP licence number and verify it on the NSW Fair Trading website. Inquire about their preferred membrane systems, cure times, and dive into warranty specifics—cover duration, coverage scope and claim procedures. Finally, request recent project photos and testimonials to gauge workmanship quality and customer satisfaction.
