Waterproofing for bathrooms, balconies & outdoor areas

Waterproofing sits behind the tiles and finishes, but it does some of the most important work in a bathroom, laundry or balcony. PB47 Construction prepares and waterproofs these areas carefully before the next stage begins.

The part you should not rush

Good waterproofing starts with good preparation

A membrane can only perform properly when the surface underneath is sound and the details around corners, drains and pipe penetrations have been handled carefully.

We first look at how the area is built and where the water needs to go. Then we prepare the surface, address the important junctions and apply a suitable waterproofing system for the agreed job.

  • Clear explanation of what is included
  • Care around wall-to-floor junctions and penetrations
  • Attention to falls, drains and doorway thresholds
  • Waterproofing coordinated with PB47 tiling work

Where we can help

Waterproofing for wet and exposed areas

Every space deals with water differently. We look at the location, the surface and the finish that will sit above the waterproofing before confirming the scope.

Bathrooms & showers

Waterproofing for shower areas, bathroom floors, walls and other wet zones before tiling. Extra care is given to corners, drains and pipe openings.

Laundries

Practical preparation and waterproofing around floors, wall junctions, wastes and plumbing points in hardworking laundry spaces.

Balconies

Balcony waterproofing planned around drainage, falls, edges, thresholds and the outdoor finish that will be installed above it.

Outdoor areas

Selected outdoor areas assessed for weather exposure, movement, drainage and compatibility with the planned surface finish.

Repair preparation

If an existing area shows signs of water damage, we inspect the visible condition and explain what may need to be opened up before repairs can be priced.

Waterproofing & tiling

Keeping both stages with PB47 can make scheduling clearer and help the waterproofing and tile installation work together as one scope.

How the work moves forward

A straightforward waterproofing process

01

Inspect

We look at the area, access, surfaces, drainage points and the work planned after waterproofing.

02

Prepare

The area is cleaned and prepared, with corners, joins and penetrations addressed for the agreed system.

03

Waterproof

The waterproofing system is applied methodically, including the important detail areas that are easy to overlook.

04

Next stage

We confirm when the area is ready for the next part of the project, such as tiling or another finish.

Before we quote

A few details help us understand the job

Send the project suburb, a few clear photos and the approximate size of the area. Let us know whether it is a new build, renovation or an existing area with signs of a leak.

If the project also includes demolition or tiling, mention that too. We can then advise whether an on-site inspection is the right next step.

Common questions

Can PB47 waterproof and tile the same area?

Yes. Waterproofing and wall or floor tiling can be included in one agreed scope, which keeps the work sequence easier to manage.

Do you work on balconies as well as bathrooms?

Yes. We handle internal wet areas, balconies and selected outdoor areas after assessing the location and planned finish.

Can you quote from photos?

Photos and measurements help with the first conversation, but some jobs need an on-site inspection before the full scope and price can be confirmed.

What happens if there is already a leak?

We inspect the visible condition and discuss what may need to be removed or investigated. The source of water is not always directly above the visible damage.
