Teretek® Repairs and Strengthens Foundations of Aged Care Building

The residence comprises a single building, with several wings that accommodate 1,700 residents and is staffed by more than 2,500 aged care workers.

Over time, a large 125m long section at the back of the building had experienced settlement of up to 180mm, which had affected an approximately 2500m2 area spanning three separate wings, a shed and connecting pathways between the wings.

Remediating the site posed a number of logistical issues as the three wings backed onto a neighbouring property, with limited access for vehicles and equipment.

Additionally, a large 4m deep stormwater pipe ran alongside a retaining wall that was located approximately 4m from the rear of the building.

In addition to the site’s access challenges, strict health and safety protocols were in place as McKenzie’s first priority is to protect the comfort and wellbeing of those in its care at all times. Excavation was deemed unviable as the facility would have been forced to close three wings and relocate its residents. It would also have been very costly and time consuming.

Therefore it was important that the ground improvement work could be undertaken with minimal disturbance to residents and within strictly mandated guidelines due to the COVID-19 pandemic.

It was important to accomplish this without disrupting the residents or the facility’s day-to-day operations. The work also needed to be undertaken while adhering to strict COVID-19 health and safety protocols.

With the health and safety of elderly residents a priority, Teretek’s non-invasive and low-impact application process ensured the work could be undertaken efficiently while allowing the residents to remain in

their rooms. Alternative ground remediation methods, such as underpinning, would have required excavation, taken months to complete at great expense, and caused major disruption to residents who would have needed to vacate the building.

While site access was initially identified as a challenge, thanks to the cooperation of a neighbouring property owner who granted access to their yard, Mainmark was able to access the site through the neighbour’s boundary fence. This required the removal and eventual replacement of the fence. The property owner was offered compensation for the intrusion, which they accepted and generously donated to charity.

This challenging project was carried out while adhering to strict COVID-19 health and safety protocols, which included the team undertaking additional measures such as registering on site everyday, undergoing daily health checks, and wearing approved security passes.
