Balcony Restoration

Step 1, Complete surveys, sounding, probes, structural review, access design, resident protection, drainage testing, and repair mapping.

Step 2, Install platforms, shoring where required, exclusion zones, interior protection, and debris and water containment.

Step 3, Remove concrete to sound limits, assess reinforcement and anchors, and complete directed steel treatment or replacement.

Step 4, Rebuild slab, soffit, edge, slope, drain, threshold, joint, and railing details with controlled placement and curing.

Step 5, Prepare and install protection systems, test drainage, inspect guards, remove access safely, and close location-based records.

Harrowgate restores balconies from the concrete outward. The sequence preserves safety, removes deteriorated material, rebuilds the structural section with compatible repairs, restores drainage, and installs a continuous traffic-bearing membrane tied into every edge and penetration.

Investigation and access planning. We review the consultant survey, hammer sounding, crack maps, leakage, coating condition, guard anchorage, and drainage. Swing stages, scaffolds, lifts, and protected ground zones are selected for the elevations and site constraints. Balcony closures, interior access, noise periods, and falling-object protection are coordinated before removals begin.

Sawcutting and concrete removal. Repair boundaries are sawcut to avoid feathered patches. Chipping proceeds to sound concrete without damaging reinforcement that remains in service. Overhead and edge removals are controlled in small areas, and debris is contained at source. Newly exposed conditions are documented for consultant review before patching.

Reinforcement and substrate preparation. Corroded bars are exposed sufficiently for cleaning and repair placement around them. Section loss is reviewed by the structural engineer, and supplemental steel is installed where directed. Concrete surfaces are rough, sound, clean, and saturated surface dry for cementitious materials where specified. Bonding treatment follows the approved repair system.

Forming and repair placement. Soffit, fascia, curb, and edge forms are tight and braced to restore the original geometry. Hand-placed mortar serves smaller repairs, while formed-and-poured or pumpable repair concrete serves larger volumes. Material is consolidated around steel and cured to control shrinkage. Form removal does not occur until the repair can support itself without edge damage.

Slope, joints, and penetrations. Low areas are corrected with bonded screed where the design permits, and door thresholds are integrated without trapping water. Moving cracks and joints receive flexible treatment. Guard posts, scuppers, drains, wall junctions, and drip edges are detailed before the field membrane so runoff cannot bypass the waterproof layer.

Pedestrian membrane and turnover. Prepared repairs receive primer, elastomeric membrane, aggregate wear coat, and colour-stable topcoat selected for exterior pedestrian exposure. Coating turns up at walls and curbs and terminates cleanly at edges. Guards and accessories are reinstated without puncturing unprotected membrane, then each balcony is inspected before access is returned.

We review soffits and slab edges from below as well as walking surfaces from above. Closeout checks patch soundness, membrane continuity, texture, drainage, sealant adhesion, guard interfaces, and clean terminations. Product and repair records are organized by elevation and stack so future inspections can distinguish original concrete, completed repair zones, and coating transitions.
