Rosewood Aged Care

Adding Life to Concrete – How MARKHAM applied multiple concrete treatment systems to this unique aged care project in West Perth.

The Objective

There were two sets of challenges involved in this project at thee Rosewood Aged Care facility.

Firstly, waterproofing the basement. The basement was excavated around a heritage-listed building, which had to stay undamaged for the duration of the works. Piles and shotcrete were implemented for the construction, but there was no scope to install a membrane due to space and other limitations.

Second were the requirements for moisture control and permanent hygiene protection for the interior floor slabs of the residential parts of the building. This is a more routine challenge, faced by aged care facilities with concrete floor slabs.

Our Solution

As regards the waterproofing, MARKHAM was able to assist with a holistic three-part system. The shotcrete itself was made waterproof by means of AQURON 300 admixture and AQURON 2000 spray-applied treatment. The penetrations and joints were sealed with CONQOR 47B delayed swell waterstop gasket.

Inside the residential zone, AQURON 2000 MEDI+ was applied to the floor slabs, for moisture control, permanent hygiene protection, and the added benefit of enhanced concrete curing.

Positive Results

Despite the challenges of the Rosewood Aged Care site, the system was successfully implemented. The MARKHAM team worked seamlessly with the principal contractor to ensure absolute minimal disruption to the construction schedule.

The moisture control ensured no adhesion or compatibility issues with flooring or adhesives. Permanent hygiene protection eliminates bacterial activity within the slab, and the resulting odours. This treatment never needs re-application.

This was a win for the construction team and for the asset owners.
