Leaking shower? Water stains on ceilings? Mould returning no matter how often you clean?

In most cases, the real problem is failed waterproofing behind the tiles.

Waterproofing is the most critical stage of any bathroom construction or repair. If it fails, tiles, grout and silicone will not stop water penetration.

Why Waterproofing Matters

Tiles and grout are not waterproof.

Every compliant bathroom in Melbourne must have a waterproof membrane installed beneath the tiles to prevent moisture from penetrating wall frames, subfloors and adjoining rooms.

When waterproofing fails, you may notice:

  • Persistent leaking
  • Water damage to ceilings below
  • Damp or swollen skirting boards
  • Loose or drummy tiles
  • Recurring cracked grout
  • Mould growth and musty odours

Ignoring these signs can lead to structural damage, timber rot and expensive rectification work.

We fix the issue at its source, not just the surface symptoms.

Our Bathroom & Shower Waterproofing Services

Shower Waterproofing

We install compliant waterproofing for:

  • Shower recesses
  • Walk-in showers
  • Hob and hobless shower designs
  • Shower bases and floors
  • Wall and floor junctions

If your shower is leaking in your Melbourne home, waterproofing failure is usually the underlying cause.

Bathroom Floor Waterproofing

Bathroom floors must be properly waterproofed to prevent moisture from penetrating into the subfloor and adjacent rooms.

We ensure:

  • Correct floor falls to waste
  • Reinforced wall and floor junctions
  • Proper membrane thickness
  • Full floor coverage where required
  • Adequate curing time before tiling

Waterproofing for Bathroom Renovations

If you are renovating your bathroom in Melbourne, waterproofing must be installed before any tiles are laid.

We work on:

  • Full bathroom renovations
  • Shower rebuilds
  • Partial bathroom upgrades
  • Structural repairs

A renovation without compliant waterproofing risks future failure and costly repairs.

Waterproofing Rectification for Leaking Showers

If your shower is already leaking, we:

  1. Inspect and confirm membrane failure
  2. Remove tiles and screed where necessary
  3. Repair substrate damage
  4. Install a new compliant waterproof membrane
  5. Allow correct curing before retiling

Surface sealers and quick patch repairs are temporary solutions. Proper membrane replacement is the only long-term fix.

Our Waterproofing Process

    1. On-Site Inspection – We assess the shower or bathroom to determine the extent of failure and moisture damage.
    2. Controlled Tile Removal – Where required, tiles are removed carefully to access the underlying membrane.
    3. Substrate Preparation – We repair damaged surfaces, ensure correct falls and reinforce all critical junctions.
    4. Membrane Installation – A compliant waterproof membrane is applied to floors, walls and penetrations in accordance with AS 3740.
    5. Curing Period – The membrane is allowed to cure fully before any tiling work begins.
    6. Certification – Waterproofing certification can be provided where required under Victorian regulations.

Bathroom & Shower Waterproofing FAQs

You may need new waterproofing if:

  • Your shower is leaking into adjacent rooms
  • The ceiling below shows signs of water damage
  • Grout repairs repeatedly fail
  • Tiles are loose or lifting
  • Your bathroom is more than 10 to 15 years old
  • You are undertaking a renovation

Waterproof membranes deteriorate over time, particularly if poorly installed. Replacing them correctly protects your home and prevents ongoing structural damage.

Common signs include leaking into surrounding rooms, persistent damp smells, mould growth and recurring cracked grout. A professional inspection can confirm membrane failure.

In most cases, failed waterproofing requires tile removal to access and replace the membrane beneath. Surface sealing products are temporary and do not solve underlying issues.

When installed correctly and in accordance with standards, waterproofing membranes can last many years. Failures are typically due to poor installation or structural movement.

Yes. Waterproofing certification can be provided where required to confirm compliance with Australian Standards.

Most bathroom or shower waterproofing projects take one to two days for application, followed by required curing time before tiling can proceed.
