What United Trade Offer

What is the Remedial Waterproofing?


Corrective/Adaptive Waterproofing: The Waterproofing system has failed, but is being replaced with a system to prevent water intrusion. Remedial work is a note of other, because it deals with issues once the damage has taken place – meaning it’s a more precise action.


We apply this service to:


  • Balconies
  • Rooftops and terraces
  • Basements and retaining walls
  • Kitchens, bathrooms, and wet areas
  • Movement joints and mullions

These services have particular relevance in Sydney due to its coastal environment and the seasonal rain and humidity, which play a huge part in material disintegration here.


Why you must obtain remedial waterproofing in Sydney


Sydney Weather for Waterproofing: Sydney weather is different and has its own set of problems when it comes to waterproofing. Heavy showers, salty air if near the coast, extremes of temperature, and local pollution can all take their toll on your roof.


Here are some general signs to watch for when determining if you need remedial waterproofing in Sydney.


  • Pooling of water on balconies or flat roofs
  • If you have mold and mildew or musty odors inside, some mold hidden under stuff, even the mislaid Christmas ribbon when the cats were kittens – you probably do.
  • Paint blistering, or plaster falling apart
  • Hairline cracks to walls, tiles, or render
  • Leaks in basement walls or on bathroom floors

If left unchecked, these issues can lead to physical damage, safety concerns, and a devaluation of your property.


How to Repair a Leaking Balcony in Sydney


Other than sealing a few cracks, if you’re thinking of how to fix a leaking balcony in Sydney, well, it’s more than that. It won’t be solved by Band-Aids but by solutions that get at the underlying causes and are long-lasting. Here’s an overview of how United Trade addresses leaking balconies:


Step 1: Site Visit for Inspection and Documentation: We also deploy modern equipment like thermal imaging, moisture sensors, and dye testing to identify hidden leaks and evaluate structural damage.

Step 2: Remove the damaged material: Tiles, membranes, or coatings are stripped off to expose the base layer. This will enable us to spot any broken or chipped concrete.

Step 3: Damage Repair & Surfacing: We do concrete work, re-screeding, and grinding in preparation for waterproofing. This will allow the membrane system to adhere and perform accordingly.

Step 4: Install the Waterproof Membranes: Performance waterproof membranes are used to ensure that your feet stay dry. We choose products based on exposure, traffic levels, and building materials.

Step 5: Retiling and the Final Touches: Once waterproofed, the balcony is retiled/surfaced in its original or new design, maintaining its use and appearance.

Step 6: Final Leak Testing: We will flood test and post-repair inspect to ensure the repair is successful and complies with Australian standards.
