A Scope of Works was prepared by BellMont addressing structural restrengthening works and the installation of a new membrane compatible with the existing. Owing to the original construction of the building roof area, the new membrane was required to be detailed into the building parapet walls and continue over the parapet to ensure a continuous waterproof seal. The further requirement dictating the selection of the membrane system was the minimal time frame available for installation and curing. As such, the Emer-Clad liquid trafficable membrane system was specified for the roof membrane system.
Structural restrengthening to the façade was undertaken utilising a combination of reinforcing bars systems supplied by Helifix. The structural intent of the strengthening was to form a single structural panel at the lower levels by tying the brickwork together.
As work progressed, it was noted that while the original membrane had indeed failed, it was not the only source of water penetration—many hidden and empty service lines service lines to the laundry were found to be filled with water and draining beneath the membrane.
Over the years the pipes from the wet areas had corroded, been updated or partly disconnected so that the waste water now flowed into various uncontrolled locations. These issues were also addressed as a part of these works allowing for hydraulic design services to be provided by BellMont.
The Owners Corporation and Strata Manager quickly moved to renew all such service lines and allow the project to be completed. Record rainfall levels since completion have not resulted in any water penetration since completion.
