Balcony Waterproofing

All too often, penetration of water through the top surfaces and exposed edges of both reinforced concrete balconies and timber framed balconies, leads to deterioration of the balconies themselves, and other significant defects, such as concrete spalling (which we will discuss later), corrosion of balustrade connection points and bases, failure of soffit coatings and loss of adhesion of soffit coatings, and other unsightly flaws such as the leaching of soluble salts.

 

The correct approach, is of course is the installation of robust and appropriate waterproofing membrane system "that lasts"! The use materials that are not of the optimum type, that are below thickness or required dry film build, that re-emulsify etc etc will only lead to inordinate repair costs. Tiling by the way, is not an effective or acceptable waterproofing measure. Membranes normally, and best, are situated to the structural deck, below the tile bed and tiles. There is a lot of information and other work details in relation to appropriate waterproofing of balconies. Please speak to us about this.

  • Removal of tiles and tile bed back to the structural slab.
  • This is a timber framed, aluminum clad suspended balcony, one of many at this complex. We removed the wall and balustrade cladding and the deck cladding. The deck cladding was replaced with 12mm compressed fibre cement sheeting. New and well designed drainage was installed.
  • A new sheet membrane was installed (photo showing first layer only). The cladding to the walls and balustrade was replaced. Screeding and tiling finished the deck. Expansion joints included.
