Bathroom Waterproofing Sydney

Protect Your Bathroom with Expert Waterproofing Services

Bathroom waterproofing in Sydney is a sealed membrane applied to the floor, walls and shower recess before tiling, and it has to meet Australian Standard AS 3740 to protect the home from water damage.

Whether you’re renovating your bathroom or building a new one, our plumbing professionals provide high-quality waterproofing solutions that prevent leaks and prolong the life of your bathroom. Our licensed waterproofing specialists use premium-grade materials and proven techniques to deliver a long-lasting, water-tight seal .

Bathroom waterproofing in Sydney: what the job involves

Waterproofing is done after the bathroom is stripped back and before a single tile goes down. The membrane runs across the floor and up the walls, with extra care at the shower recess, the floor waste and every corner and joint, because that is where water finds its way through.

Because it is hidden under the tiles, a failed membrane often shows up as a damp smell, lifting tiles or a stain in the next room long after the job. That is why the work is done once and done properly during the renovation, with the bathroom plumbing set out around it.

Common Bathroom Waterproofing Problems (and How We Fix Them)

“My last waterproofing job failed, and now my bathroom has water damage.”

Improper waterproofing can lead to water leaks, peeling paint, and mould build-up. We assess the extent of the damage, remove faulty waterproofing layers, and apply a new, high-quality membrane to prevent future leaks.

“The previous contractor rushed the waterproofing, and now my tiles are lifting.”

Waterproofing needs time to cure properly before tiling begins. We follow the correct drying and curing process, ensuring a secure bond between waterproofing layers and tiles for a durable finish.

“There are cracks in my shower floor, and water is seeping into the walls.”

Cracks indicate poor waterproofing or substrate movement. We repair the affected area, apply flexible membranes, and reinforce joints to ensure a water-tight, crack-resistant seal.

“My bathroom constantly smells damp even after cleaning.”

A persistent damp smell can indicate hidden leaks or moisture trapped beneath tiles. We conduct moisture testing, locate problem areas, and apply professional-grade waterproofing solutions to eliminate the issue.

“Water is leaking into the room next to my bathroom.”

This is often due to failed waterproofing in the shower or around wet areas. Our team identifies the source of the leak, removes faulty waterproofing, and applies new protective coatings to ensure no further seepage.
