This is a case study by Paul Evans involving an educational facility in Melbourne, where the existing rooftop membrane failed and needed integration with a new membrane for building a large decking. The project was complex, requiring the incorporation of engineering elements and correct waterproofing techniques.
Problem
The existing rooftop membrane failed, requiring remediation.
Solution
Integration with a new membrane and building a large decking.
Process
Stripping and cleaning the area, detailing each new stirrup used for supporting the decking, and isolating problem areas.
Materials Used
Sealing and protecting the membrane using liquid rubber spray, a topcoat, a soft back protection sheet with stick back, and synthetic grass.
Special Product
Introduction of “disarmament blue,” a semi-adhering substance that can be peeled off and re-stuck if needed.
Case Study
Application of liquid rubber spray over the entire area, building a deck on top, and adding synthetic grass later.
Outcome
A visually stunning and watertight rooftop balcony.
This study provides a comprehensive overview of a complex waterproofing project, showcasing the expertise and innovative solutions used to achieve a successful result. It serves as an informative guide for those interested in understanding the intricacies of waterproofing a concrete rooftop terrace.
