Remedial Waterproofing to Leaking Concrete Rooftop
Video below explains how Findlay-Evans Waterproofing rectified water leak problems for this challenging rooftop, which also involved difficult access for the Team and equipment.
Project: Badly deteriorated waterproof membrane causing water leaks in concrete roof slab
Best Membrane for Concrete Roof Slab
However all our Team are "Working at Heights" & "Confined Spaces" compliant.
And our spray apply waterproofing system is mobile and easily transported to rooftops.
The Team successfully installed - on time and on-budget - a UV stable waterproof membrane on a concrete slab roof.
Prior to the new membrane, this rooftop had an extremely deteriorated existing polyurethane roof sealant that was causing quite extensive water leaks.
Preparing Concrete Surface Prior to Waterproofing
It is extremely important to prepare and clean any surface meticulously before applying a new waterproofing membrane.
Our Team had to complete extensive preparation to the badly leaking and deteriorated concrete substrate prior to spray-on application of a Liquid Rubber Membrane.
- Our Waterproofing Team was the nominated waterproofing contractor to provide a permanent solution for a membrane to fix a leaking concrete roof for a commercial large flour mill.
Existing failed roof membrane
Removal of existing failed membrane prior to installation of new LIQUID WATERPROOFING.
- To ensure a permanent waterproofing solution for this roof, we started off by removing the old defective membrane by using mechanical scrapers.
- Once the deteriorated polyurethane membrane was removed, we then proceeded to cleaning the concrete roof to ensure a good adhesion for the new Liquid Rubber Membrane.

Waterproofing Method for Flat Concrete Roof
- Although the existing concrete roof was in good order, in general there were some areas that required rescreeding and leveling out to create a sound roof substrate.
- We went ahead and screeded these areas with flexible screed, and then coated with Liquid Rubber waterproofing membrane.
- The entire concrete roof was coated with Liquid Rubber including an interlacing fiberglass mesh to make the membrane even more robust.
- As this building was particularly big, there was a lot of movement and therefore Liquid Rubber was the ideal solution to waterproof this flat roof and stop water leaks.
Best Waterproofing Product for Roofs
Liquid Applied Waterproof coatings have become the
industry standard to seal leaking concrete and metal roofs.
Using flexible and monolithic Liquid Rubber membranes.
Liquid Rubber is highly flexible waterproofing membrane.
This allows for building movement; contraction, expansion and vibration.
Spray On Waterproofing - Liquid Membranes
- To finish off the final membrane we roller applied two coats of the heat reflective Thermo Top Coat in light grey colour.
- Thermo Top Coat is not only pleasing to the eye but also provides thermal properties reducing the interior temperatures by up to 8 Celsius degrees. This helped with the internal ventilation keeping the building cool inside during the summer months.
- The project turned out great everybody being happy with the outcome.

The Australian Institute of Management (AIM) recently engaged F.E.W Waterproofing to resurface the Level 6 plant area which was prone to water leakage.
Liquid Rubber was used and is brilliant seamless product; we were very impressed with the finished product.
The F.E.W workmanship was of a high standard. Since having the Liquid Rubber laid down we have not experienced any water leaks.
