In early 2025, Cyclone Alfred unleashed torrential rain and flooding across Brisbane, Gold Coast, and the Northern Rivers. One home that was breached by floodwater, suffered significant damage. This wasn’t just rainwater—it was Category 3 floodwater, carrying dangerous contaminants that rendered the lower parts of the home unsafe.
Biodec was called in to remediate the property to IICRC S500 standards, ensuring the home could be safely reoccupied.
Despite the shallow depth of flooding, the source of the water made it particularly hazardous. Category 3 water, often referred to as “black water,” includes water from:
In this case, stormwater runoff from Cyclone Alfred entered the home, soaking porous materials like plasterboard, insulation, and timber framing.
Upon arrival, Biodec conducted a full assessment and developed a remediation plan based on Category 3 protocols, which include more extensive removal and disinfection than lower-category incidents.
Given the contamination risk and absorption depth, Biodec stripped plasterboard, skirtings, and insulation up to 1200mm, ensuring all contaminated material was removed.
All exposed surfaces, including timber framing and slab edges, were thoroughly cleaned and treated with a hospital-grade disinfectant rated for biohazard environments.
Drying equipment was installed and monitored daily to ensure no residual moisture remained. Moisture maps were created as part of the validation process.
Biodec provided a detailed report for insurance and client records, including:
After 7 days of structured drying and sanitization, the home was declared safe for rebuild. Biodec follows the IICRC S500 rigorously—ensuring that no shortcuts are taken when health and safety are on the line.
