Waterproofing Repairs for Concrete Roof
Case Study - Sunshine Hospital Melbourne
Water leaks from the existing roof sheet membrane was badly deteriorated & causing severe damage to rooms below.
Liquid Applied Membranes (LAM) were chosen as the waterproofing product for this project due to the very "busy" rooftop deck - i.e utilities, pipes & infrastructure - that would have been far too costly to remove and re-install.
A waterproofing company that thinks CONSTRUCTION
Findlay & Evans were contracted to provide the waterproofing remediation method to solve these roof water leaks while also ensuring there was minimal disruption to hospital services below.

Roof Repairs & Restoration
Concrete Roof - Leaking Membrane
This had a "busy" rooftop plant deck with low suspended pipes & infrastructure.
The waterproofing membrane needed to seal around all these roof structures.
The concrete roof had an old butynol (BUR) waterproof membrane applied sometime ago probably, 25 - 30 years ago.
This damaged sheet membrane on the roof had to be removed completely which was leaking & causing extensive damage to rooms below.

Rooftop Waterproofing System
Findlay-Evans Team removed the existing sheet membrane and then thoroughly cleaned the entire roof surface prior to membrane installation.
Liquid Applied Waterproofing
A Liquid Waterproofing System allows the membrane to be painted on by brush - this allows a permanent watertight seal that can be painted & contoured to the shape as required.
Liquid Rubber is the perfect waterproofing product for "busy" roof plant decks.
Waterproofing Preparation
Masking around all plant deck services provided a neat finish for the spray-application of LIQUID RUBBER MEMBRANE to the entire roof surface.
Masking Prior to Membrane Application
Roof Waterproofing – Liquid System
After hand detailing, masking and preparation, a base coat of Liquid Rubber membrane was spray applied by our dedicated spray rig which is portable for rooftop waterproofing.
Once the base waterproof coat was completed, we then moved forward with the spray application of the final coating.
This project involved a three-coat spray applied waterproofing system - ensuring the rooftop had a long lasting, permanent and robust waterproof membrane.

Liquid Waterproofing Contractors - Melbourne
We provided a permanent waterproof coating on all roof surfaces - even those not in use - as these maybe an obvious point of future water ingress.
Roof Waterproofing System
This waterproofing project also included membranes that needed to be applied to the roof sections of the Sunshine Hospital stair access towers.
The roof of the access towers were in extremely bad condition with little or no maintenance performed for many years.
Access to the towers' roof was by external scaffolding which needed to be erected.
We installed a robust roof membrane on all stair access towers by application of several layers of Liquid Rubber coatings.
