What Do People Ask About Waterproofing in Crows Nest?
How much does bathroom waterproofing cost in Australia?
Waterproofing a standard shower costs $300–$600. A full bathroom including shower, floor, and bath area costs $500–$1,200. Balcony waterproofing costs $80–$150/m². These are labour costs only — materials add $50–$200 depending on the membrane system used.
Do I legally need to waterproof my shower?
Yes — AS 3740 (Waterproofing of domestic wet areas) is mandatory under the National Construction Code. All showers, bath surrounds, laundries, and balconies must be waterproofed to this standard. Failure to comply can void home insurance claims related to water damage.
How long does waterproofing last in a shower?
A quality waterproofing membrane correctly installed should last 10–15 years minimum. Cheap products or incorrect installation fail much sooner. The grout and tile system on top doesn't waterproof the shower — the membrane underneath does. Grout cracks don't mean the waterproofing has failed.
How do I know if my shower is leaking?
Signs include damp patches on adjacent walls or floors, mould behind tiles, peeling paint, efflorescence (white mineral deposits), soft or spongy tiles, or a musty smell. A licensed waterproofer can perform a flood test to confirm leakage before expensive rectification work begins.
Can you waterproof over existing tiles?
Generally not recommended for showers. If the existing tiles are sound and firmly bonded, a liquid membrane can be applied over them in some scenarios. However, if there are any cracked, hollow, or loose tiles, these must be removed and the substrate repaired before new waterproofing is applied.
What types of waterproofing membrane are used in Australia?
The main types are: sheet membranes (peel-and-stick or torch-on), liquid-applied membranes (polyurethane, acrylic, or bitumen), and cementitious membranes. Liquid polyurethane systems are the most common for bathroom and balcony applications due to ease of application and reliability.
How long do I need to wait after waterproofing before tiling?
Liquid membranes require 24–48 hours curing time (depending on the product and conditions) before tiling. The membrane must be fully dry and tested before tiling begins. Flood testing (ponding water for 24 hours) should be done before tiling to confirm there are no defects.
How do I fix a leaking balcony in Australia?
Balcony repairs typically involve removing tiles, inspecting and repairing the substrate, applying a new waterproofing membrane system, and retiling. Costs range from $3,000–$10,000 depending on size and extent of damage. In apartment buildings, responsibility for waterproofing depends on the strata plan — check with your owners corporation.
