Professional Balcony Waterproofers Melbourne

A leaky balcony is a common issue across all sorts of buildings and structures. These leaks can result in serious problems such as timber rot, concrete spalling (also known as concrete cancer) due to moisture seepage, electrical faults, structural collapse, and pest infestations.

If left unaddressed, balcony leaks can lead to costly and unsightly damage to balcony surfaces, as well as the areas below them. This damage may include cracks in tiles, efflorescence, calcium buildup, and the lifting or detachment of tiles or coatings. Moisture leaks or ingress are the primary defects found in buildings and structures in Melbourne.

Causes of Leaking Balconies

  • Building Movement – Shifting or settling of the structure can compromise the integrity of balcony waterproofing.

  • Incorrect Application or Failure of Waterproofing Membrane – Improper installation or use of substandard materials can lead to membrane failure.

  • Poor Substrate or Structure Construction – Inferior quality materials or construction techniques can contribute to balcony leakage.

  • Inadequate Drainage or Poor Substrate Gradient – Insufficient slope or improper drainage can result in water pooling on the balcony surface.

  • Inadequate Adjacent Flashings – Lack of proper flashing around windows or doors can allow water infiltration.

  • Waterproofing Membrane Failure – Most balcony leaks occur due to failure of the waterproofing membrane, often caused by incorrect application or the use of low-quality products.

  • Minimal Falls – Balconies in high-rise apartments are often built with minimal slope and inadequate drainage, increasing stress on the waterproofing system.

  • Extreme Weather Conditions – Heat, cold, wind, and rain can cause expansion and contraction of balcony joints, exacerbating leakage.

  • Deterioration of Perimeter Seals – Over time, exposure to the elements can degrade seals around the edges of the balcony.

  • Cracked, Porous, or Loose Grout – Damaged grout can allow water to seep beneath tiles, leading to leaks.

  • Cracked or Broken Tiles – Damage to tiles can compromise the waterproofing barrier of the balcony.

If you have an area that requires waterproofing, SCR’s Melbourne-based team can help


It’s advisable to waterproof your balcony during construction or renovation. However, if you notice signs of water damage such as cracks, leaks, or efflorescence, immediate waterproofing is necessary to prevent further deterioration.

The durability of waterproofing varies depending on factors such as material quality, installation method, and maintenance. Typically, professionally installed waterproofing can last anywhere from 5 to 15 years, but regular inspections and maintenance can extend its lifespan.

The time it takes to waterproof a balcony can vary depending on the size of the balcony, the extent of the work required, and the weather conditions. In general, however, balcony waterproofing can take anywhere from a few days to a week or more to complete.

Yes, SCR Melbourne provides its clients with a waterproofing certificate to confirm the balcony has been waterproofed according to the Australian Standards AS4654.2-2012.


Here’s what our happy clients had to say about our services:

We had the SCR team waterproof our balcony and replace the tiling. They were 100% professional from the quote through to the completed job. We were fully informed all the way, they were on time and the workmanship was excellent.


We engaged SCR to rip up, waterproof and retile our apartment balcony. Now we have a terrace which has not leaked and looks wonderful. We are very happy and would not hesitate to recommend SCR to others.


SCR did a great job re-waterproofing my apartment’s large outdoor deck. Staff were pleasant, hard working and obviously very knowledgeable.
