Warning Signs

Critical Laundry Waterproofing Warning Signs

Recognize these early indicators of water damage before minor moisture issues cause expensive structural decay.

Swelling skirting boards

MDF or timber skirting boards absorbing moisture from unseen floor leaks.

Lifting floor coverings

Vinyl or timber floors outside the laundry beginning to warp or lift.

Musty cabinet smells

Damp odors inside laundry cabinets often indicate slow plumbing leaks degrading the wall.

Water pooling around waste

If water does not drain properly, the floor waste seal may be compromised.

Damp patches on adjoining walls

Moisture traveling through the wall into adjacent hallways or bedrooms.

Rust on washing machine feet

Constant unseen moisture on the floor causing metal appliances to rust prematurely.

Our Process

Our Proven 4-Step Process

From Problem to Peace of Mind

STEP 1

Substrate Preparation & Cleaning

Old flooring materials, debris, and contaminants are completely stripped back to ensure the laundry subfloor is completely dry, structural, and dust-free.

STEP 2

High-Adhesion Floor Priming

A specialized rapid-drying primer is applied across the entire concrete or tile underlay substrate to facilitate deep, permanent membrane adhesion.

STEP 3

Plumbing & Waste Detailing

We detail around floor wastes, washing machine taps, and drainage outlets using flexible polyurethane sealants to seal high-risk leak zones.

STEP 4

Continuous Tray Membrane Coating

A flexible Class III liquid membrane is applied across the entire laundry floor and up the walls to form a watertight containment tray that prevents overflow damage.

Service FAQs

Frequently Asked Questions About Laundry Waterproofing

Got questions about laundry waterproofing in Sydney? Find technical answers regarding membrane specifications, curing times, and warranties below.

In typical Sydney weather, Class III liquid membranes require 24 to 48 hours to fully cure before tiling or screeding. Cold or humid conditions may extend curing times. We verify dry film thickness and cure state prior to authorizing follow-on trades.
Swelling MDF or timber skirtings indicate water is bypassing the internal wet area barrier and tracking laterally beneath tile beds into adjacent hallways or bedrooms. This signals a compromised membrane or missing perimeter upturn.
We construct a seamless waterproof containment tray across the full laundry floor with 150mm wall upturns and detailed floor waste seals. If a washing machine hose ruptures, the water is safely impounded and directed into the floor waste rather than flooding timber subfloors.
Yes, under the Building Code of Australia, laundries are classified as wet areas and must be waterproofed. This is essential to protect the structural integrity of your home from accidental washing machine overflows and slow plumbing leaks.
Typically, the entire floor is waterproofed along with perimeter wall upturns (usually 150mm high) to create a secure 'tray'. Full wall waterproofing is generally only required behind tubs and sink splashbacks to protect the drywall from splashing.
No. To ensure a continuous, seamless membrane application across the entire floor, the area must be completely cleared. Attempting to waterproof around built-in cabinetry creates weak points that are highly prone to future leaks.
