Where Waterproofing Is Required

Waterproofing is required in areas exposed to regular moisture and water.

This includes:

Shower floors and walls

Bathroom floors

Bathroom walls in wet zones

Around baths

Laundry floors

Behind laundry tubs

Powder rooms with floor wastes

Balcony and external wet areas where applicable.

In showers, walls are required to be waterproofed to a specified height. Bathroom floors must also be waterproofed and correctly sealed around penetrations such as pipes and drains.

Each area is assessed to ensure the correct preparation and application method is
used.

Why Proper Waterproofing Matters

Incorrect or inadequate waterproofing can lead to serious problems over time.

Common issues caused by poor waterproofing include:

Water leaks into adjoining rooms

Rotting timber framing

Mould growth

Damaged plaster and paint

Structural deterioration

Expensive rectification work.

Water damage often occurs behind tiles where it is not immediately visible. By the time signs appear, repairs can be significant.

Proper waterproofing protects your investment and ensures your bathroom or laundry performs as it should.

Integrated with Your Tiling Project

Waterproofing is completed as part of the preparation stage before tiling begins.
Surfaces are assessed, cleaned and primed before the membrane is applied in
accordance with current standards.

All work is completed carefully to ensure full coverage in required areas and correct
detailing at junctions, corners and penetrations.

Because waterproofing and tiling are handled by the same experienced tradesperson, there is consistency and accountability throughout the process.
