Balconies and terraces are among the highest-risk areas for water ingress in any building. Constant exposure to rain, direct sunlight, and thermal expansion can cause waterproofing membranes to fail, allowing water to penetrate into the slab and adjoining walls. This not only leads to cosmetic issues like tile lifting or efflorescence, but can escalate into concrete spalling, reinforcement corrosion, and even internal water damage.

Our remediation process starts with a full diagnostic assessment. Using moisture meters, core sampling, and sometimes invasive inspections, we determine whether the failure is due to membrane breakdown, substrate damage, poor drainage, or incorrect detailing at junctions and balustrades.

_{Typical scope includes:}

• _{Tile & Substrate Removal: Removing all finishes to expose the underlying slab for inspection.}
• _{Concrete Repairs: Treating and reinstating any spalling or cracked areas using structural repair mortars.}
• _{Falls & Drainage Correction: Reprofiling the surface to achieve compliant falls to drains, eliminating ponding water.}
• _{Waterproofing System Installation: Applying high-performance liquid-applied or sheet membranes, selected for UV resistance, flexibility, and long-term adhesion.}
• _{Balustrade & Edge Detailing: Reinstalling balustrades with proper waterproofing integration to prevent perimeter leaks.}
• _{Re-tiling & Finishing: Installing slip-resistant tiles or other finishes using appropriate adhesives and grouts for external environments.}

We take special care to use membrane systems compatible with the building’s environment — for example, in coastal zones we specify salt-resistant products, and in high-traffic areas we opt for abrasion-resistant coatings.

For multi-residential and commercial buildings, our access methods are tailored to minimise disruption. We coordinate works in stages to allow partial use of balconies where possible, and ensure residents are kept informed with clear timelines and updates.

The outcome is a balcony or terrace that is structurally sound, watertight, compliant with current building codes, and finished to a high standard — backed by warranties on both materials and workmanship. This approach not only resolves existing issues but also prevents costly future failures.
