The waterproofing project involved a commercial office building with several tiled balconies that had leakage problems. Despite the building being only 8 years old, issues such as surface lifting and leaking were identified, originating from the improper installation of the original membrane and poor drainage design.
Water Leak Detection:
Multiple issues with water leaks were discovered, including invasive inspections showing problems with the membrane and screed.
The screed was generally in good order but required some repairs; it was retained as a secondary barrier.
New Membrane System:
A completely new membrane system was installed, along with necessary screeding and remedial plumbing work.
Drainage Challenges:
The balcony had poor drainage with little slope, requiring the installation of new puddle flanges, droppers, and other plumbing works for proper water control.
Waterproofing Details:
Specific detailing was done with polyethylene fabric and a liquid rubber waterproofing system, strengthened with fiberglass mesh for durability.
Finishing Coats:
The waterproof membrane was over coated with a Thermo Top Coat membrane, adding robustness, and the Findlay-Evans Team efficiently prepared the balcony for tiling.
Alucobond Cladding Problems:
Water ingress was found in other areas of the building, requiring sealing and coating to prevent further water entry.
Overall Repair and Expansion:
The overall project addressed many points of water ingress, installed new expansion joints into the tile surface, and ensured the proper waterproofing of all balconies.
