What waterproofing repairs involves
Behind the tiles of every compliant shower sits a waterproof membrane. It is the barrier that stops water reaching the frame, the substrate and the rooms next door. When it fails — through age, movement, poor original application or a penetration that was never sealed — water goes past every surface layer above it.
Waterproofing repairs are the honest end of this trade. If your shower has been resealed or regrouted more than once and the damp keeps returning, the surface was never the problem. We assess whether the membrane is the cause, explain what we find, and scope the repair required to reinstate a working waterproof barrier.
This work can require removing tiles in the affected zone. We'll tell you that up front rather than selling you another surface repair that won't last.
Common problems we fix
If your shower is showing any of these, it is worth getting assessed now rather than later.
Damp that returns after resealing
The clearest sign the water is bypassing the surface entirely and moving through the membrane layer.
Water reaching an adjoining room
Moisture in the hallway, bedroom or wardrobe behind the shower wall points below the tile face.
Water in the unit below
In apartments, a compromised membrane sends water through the slab junction and into the ceiling underneath.
Penetrations never properly sealed
Taps, mixers, wastes and screen fixings are the points where original waterproofing is most often compromised.
Movement cracks through the substrate
Structural movement can tear a membrane even where the tiles above still look perfect.
Original waterproofing applied poorly
Thin coats, missed corners or the wrong primer will fail early regardless of how the shower is maintained.

Our simple repair process
Step 1
Assessment
Photos plus, in most cases, an on-site inspection — membrane problems can't be confirmed from images alone.
Step 2
Scope and written quote
We set out what's failed, what has to be opened up and what the repair involves, in writing.
Step 3
Repair and reinstate
Waterproofing is repaired in the affected zone and the surface finishes reinstated, then tested.
Waterproofing Repairs — frequently asked
How do I know if my waterproofing has failed?
The strongest indicator is damp that keeps returning after the shower has already been resealed or regrouted. Water appearing outside the bathroom or in the unit below also points below the tile surface.
Do you have to remove tiles to repair waterproofing?
Often some tile removal in the affected area is necessary to reach and reinstate the membrane. We keep it to the smallest area that produces a lasting repair, and we confirm the extent before starting.
Can waterproofing be repaired, or does the shower need replacing?
It depends on how widespread the failure is. Localised failures around penetrations or a corner can often be repaired. Where the membrane has broken down throughout, replacement is the honest recommendation.
Can you provide documentation for a body corporate?
Yes. We provide a written scope and confirmation of the repair performed, which is usually what building managers and insurers require.
Why did my previous repair fail?
Almost always because a surface repair was applied to a membrane-level problem. Grout and silicone can only stop water passing through the joints they seal.

Showers often need more than one of these. We'll confirm the right scope at assessment.
