Project summary
This case study outlines the response to a significant water loss event at a multi-storey residential apartment building in Victoria. A burst hot water pipe within the ceiling cavity of Apartment 706 on Level 7 caused the ceiling to collapse and water to travel through six levels of the building.
The incident affected eight apartments (706, 707, 708, 606, 607, 608, 509, 510), passageways and waste dump areas across Levels 1 through 7. Water extraction, moisture assessment, and drying equipment installation were completed on Day 1. A total of 14 dehumidifiers, 31 air movers, and 3 heat boxes were deployed across the site.
Key immediate actions included water extraction from all areas, removal of saturated underlay, laying floor protection on the lower ground entrance and lifts, and coordinating with a plumber to rectify the burst pipe. Ceiling removal and insulation strip-out were identified as priority works in the most heavily affected apartments.
What went wrong
A burst hot water pipe in the ceiling cavity of Apartment 706 on Level 7 caused the ceiling to collapse and water to cascade down through six floors of a residential apartment building. The extent of damage ranged from severe (ceiling collapse, maxed-out moisture readings, saturated carpets) on the upper levels to moderate moisture in passageways and waste dump areas on the lower levels.
Stakeholder impact: residents across seven levels were affected. Multiple apartments required strip-out works including ceiling removal, skirting removal, and potential flooring removal. Building management, contractors, and the insurer all required regular communication and coordinated updates throughout the response.
Key challenges identified
- Ceiling collapse in Apartment 706 requiring full ceiling removal and wet insulation disposal
- Multi-level water spread across 7 floors affecting apartments, passageways, and service areas
- Multiple flooring types (floating floor, carpet, concrete) each requiring different drying approaches
- Occupied residential building requiring coordinated access and minimal disruption
- Electrical isolation required before ceiling strip-out in affected apartments
- Deteriorated carpets unlikely to return to original condition after drying
How we restored it
Heat box drying was applied to the most heavily affected apartments (706, 606, 509) where moisture had penetrated deeply into ceilings, walls, and flooring structures. Heat boxes accelerate evaporation in enclosed spaces and were critical for areas with maxed-out readings (999 on search mode).
Standard drying setups with dehumidifiers and air movers were deployed across all remaining apartments, passageways, and waste dump areas. Equipment was positioned based on the Day 1 moisture map and repositioned daily according to updated readings.
Concrete areas in waste dump rooms were monitored using Tramex concrete meters, with readings tracked against a benchmark of 3.0 to confirm drying to standard. Equipment and technology deployed included dehumidifiers (DH), air movers (AM), heat boxes (HB), moisture meters (Search Mode and Pin Mode), Tramex concrete moisture meters, and psychrometric monitoring equipment (HygroMaster 2).
Scope of works
- Water extraction from all affected areas across 7 levels
- Removal and disposal of saturated carpet underlay
- Floor protection laid on LG entrance and lifts
- Complete moisture assessment using SM, PM, and Tramex meters
- Installation of 14 dehumidifiers, 31 air movers, and 3 heat boxes
- Approved ceiling removal and wet insulation disposal in Apts 706 and 606
- Non-salvageable skirting removal where approved
- Drill holes in ensuite and bathroom kicker plates for drying (Apt 706)
- Daily moisture monitoring, equipment repositioning, and psychrometric tracking

Frequently asked questions
Key outcomes
- Seven-level water loss from burst hot water pipe assessed, stabilised, and dried to standard
- Ceiling collapse in Apartment 706 managed with approved strip-out and insulation disposal
- 14 dehumidifiers, 31 air movers, and 3 heat boxes deployed within Day 1
- All readings brought from elevated/maxed (up to 999 SM) to at or below benchmark
- Full photographic and moisture documentation maintained via Encircle throughout
Outcome summary
A seven-level residential water loss caused by a burst hot water pipe in the ceiling cavity of Apartment 706 was assessed, documented, stabilised, and dried to standard. The ceiling collapse in the source apartment and cascading water through six additional levels required a coordinated fast-response approach across the entire building.
A total of 14 dehumidifiers, 31 air movers, and 3 heat boxes were deployed on Day 1, with moisture readings taken across all affected areas using Search Mode, Pin Mode, and Tramex meters. Daily monitoring, equipment repositioning, and approved strip-out works (ceiling removal, insulation disposal, skirting removal) ensured all areas were brought to dry standard.
Our focus throughout the project was on managing the response in a controlled and transparent way. We maintained communication with building management, residents, and the client, provided ongoing updates as conditions changed, and documented all works comprehensively via Encircle with timestamped photos and moisture readings.
