Waterproofing method for balconies require best practice & quality products  

Balconies are often designed over habitable living spaces and water leaks can be catastrophic.

Balcony Waterproofing Membranes That Work 

Why do balconies leak?

  • Obviously waterproofing membrane failures are caused by a variety of reasons however recent projects have highlighted an interesting cause.
  • Construction methods are always changing and adapting.
  • Balconies will require adequate fall in the substrate to allow the water to run off to an exit or drainage point/s.
  • Many waterproofing membranes are not designed to hold” water or sustain ponding water as it is better described.
  • The waterproofing membrane which, given time and  with thermal expansion / contraction - will cause break down or joint failure with subsequent balcony leaks.

I have been in the construction game for over 30 years, either as a Registered Building Practitioner myself & owner of Findlay & Evans Waterproofing.

I have recently noticed, either for reasons of design and/or cost considerations, subtle construction changes which have a direct impact on the success or otherwise of waterproofing membranes.

Many Balcony Floors Are Currently Being Constructed With Minimal Falls  

Particularly Evidenced In Multi-Level Apartments.

Balcony Design Affects Waterproofing

  • Balcony design has a significant effect on the choice of waterproofing product, the application of membranes and tile adhesives used.
  • The membrane must be capable of “ponding water” and the application must proceed with meticulous preparation to ensure detailing is installed correctly.

  • Unfortunately these issues are not always taken into consideration when contractors/specifiers/designers are considering waterproofing methodology for contempory balconies designed with minimal fall.
