Fix the balcony as a system. Not as a patch.
Substantial balcony leaks need more than surface sealing. SBS investigates waterproofing, finishes, falls, drainage, thresholds and perimeter details before defining the repair.
The problem is rarely just the visible crack
A balcony is layered construction. Water can enter through failed waterproofing, cracked screeds, movement joints, thresholds, outlets, balustrade penetrations and wall interfaces. The point where water appears below is often not where it entered.
Repeated patching can hide the symptom while leaving the failed system untouched. SBS separates isolated defects from broader waterproofing, drainage and interface failure.
The tile is a finish — not the waterproofing system
Tiles and grout do not replace a properly detailed waterproof layer. Falls, waterproofing continuity, upstands, movement accommodation and door/wall interfaces determine long-term performance.
Where the membrane has broadly failed, repair may require controlled removal of finishes, substrate work, fall or drainage correction, waterproofing replacement and coordinated reinstatement.
Three levels of intervention
Local repair suits an isolated defect where the surrounding system remains serviceable. Waterproofing replacement addresses broader membrane failure. Turnkey rehabilitation includes the associated building work needed to expose, correct and reinstate the balcony.
The scope can include finish removal, screed or substrate repairs, waterproofing, drainage details, thresholds, tiling and final reinstatement.
Useful answers before the inspection.
Can SBS repair a balcony without removing all the tiles?
Sometimes. A targeted repair can suit a genuinely isolated defect. Broader waterproofing failure normally requires access below the finishes.
Do all leaking balconies need a full rebuild?
No. The inspection determines whether the problem is localised or system-wide.
Can SBS handle the finishes as well?
Yes. A turnkey rehabilitation can coordinate waterproofing and reinstatement as one project.
Do you work with body corporate clients and managing agents?
Yes. SBS undertakes substantial waterproofing projects for homeowners, managing agents, trustees, body corporate clients and commercial property teams.
