Class 2 remedial
Planter box & podium remediation
Planter boxes are the most reliably failed waterproofing element in Sydney's apartment stock: permanently wet soil against a membrane never designed for immersion, roots probing every weakness, and habitable rooms directly below. Podium slabs over car parks share the pathology at larger scale. Remediation empties and strips these elements, repairs the concrete beneath, and rebuilds them as properly drained systems with protection layers, root barriers and inspection provisions the original construction skipped.
Scope
What this covers
Soil and garden removal, and strip-out of failed planter or podium systems
Concrete repair where reinforcement corrosion has followed the long-term moisture
Immersion-grade membrane systems with root-resistant protection layers
Drainage cell, geotextile and overflow provisions so water leaves by design
Reinstatement of soil, planting and podium surfaces, including pavers on pedestals for serviceability
Timing
When it's needed
Persistent damp in units or garages below landscaped areas, staining and drips at podium soffits, and planter walls showing efflorescence or rust staining. These elements are almost always common property in strata schemes, so remediation typically enters the picture through an owners corporation maintenance obligation.
Water tracking through a building can reach electrical fittings and weaken ceilings. Keep clear of sagging or stained plasterboard, never touch light fittings or switches that are damp, and isolate the affected circuit and seek help promptly where water and electricity may have met.
Quote variables
What shapes the scope
Volume of soil and landscaping to remove, store or replace
Concrete deterioration found under the failed membrane, which is priced on inspection
Whether the rebuild adopts serviceable details (pedestal pavers, accessible drains) that reduce future rectification cost
Crane or pump access for removing spoil from elevated podium levels
Waterproofing is a licensed trade in NSW, and remedial building work on apartment buildings additionally engages the design and building practitioner regime, under which designs are declared and practitioners registered. Whoever performs your remediation, ask for their contractor licence and any applicable practitioner registration, and verify both on the NSW online registers before work is engaged.
