Overhead shot of a recent balcony waterproofing job in Mount Waverley — yellow/amber membrane applied across the full deck, linear drain set at correct fall, skylight junction detailed, perimeter edges turned up against the cladding. High-end residential new build. Balcony waterproofing requires specific detailing at every edge, penetration and door threshold that bathroom waterproofing does not.
Full deck membrane applied edge to edge — no gaps, no thin spots
Linear drain set at correct fall to ensure water drains away from the structure
Skylight junction waterproofed and detailed — a critical failure point if not done correctly
Perimeter edges turned up and sealed against the cladding
Yellow membrane visible for inspection before tiling — no hiding substandard work

Balcony waterproofing must handle foot traffic, UV exposure, thermal movement and standing water — conditions far more demanding than a bathroom. We use membranes rated for external exposed applications and detail every edge, corner and penetration correctly.
