Removal of the contaminated plasterboard components (both ceilings and walls) from the next door shop side
The middle plasterboard sheet has been encapsulated with IAQ 6100 mould resistant paint.
Recommend wall to have mechanical ventilation installed and the ducting to be 200mm x 200mm to allow sufficient airflow; ducting with eave vents
The wall to be made of water-resistant and mould resistant board
The source of the moisture from the next door tenancy still exists and needs to be addressed. If left unattended, the high moisture levels will continue to allow mould growth
There was a large amount of mould growth in the wall in between 2 retail tenancies caused by condensation in the wall. The condensation was caused by a commercial refrigerator on the other side of the premises which was not properly insulated. We were called in to remediate the mould in the property.
Details of Damage
Visual mould on the wall between tenancies
Lower plasterboard wall has high moisture levels to the first joint to 1.2m
All metal frames have heavy visual rust to the base plate and studs to 1.3m
Butcher plasterboard wall has extreme visual mould growth to 2.4m- Next door roof cavity near office has visual mould growth on top of ceiling panels and walls throughout the wet area
Next door roof cavity has visual mould near the air-conditioning intake, above refrigerator display units
How We Removed the Mould
Mould remediation to building surfaces including exposed stud framing, wall cavities, walls, ceiling, floors, windows, doors, etc – by HEPA vacuuming, wash/wipe, treat vertical and horizontal surfaces
Structural drying of moist building materials via air movement and dehumidification
Antimicrobial knockdown treatment
Removed affected plasterboard to structurally sound walls. Non structurally sound walls, plasterboard has been treatment cleaned, encapsulated and left in place. (The remainder of this plasterboard to be removed in stage 2)
Application of mould encapsulation sealant to structural components
Post remediation mould sampling and testing to verify mould remediation works successfully
Disposal of all waste and debris – onsite skip bin
HVAC system to be cleaned by other contractors
Results
The client was happy that the property was restored to pre-loss condition without any evidence of the drug lab which was there.
