Paul Evans from Findlay-Evans Waterproofing details a complex case of waterproofing and decking installation for an educational facility’s rooftop.
Problem Identification
The facility’s existing membrane had failed, necessitating a new, integrated solution to allow for decking and synthetic grass installation while ensuring robust waterproofing, especially around bolted engineering elements like large umbrellas and shade cloths.
Preparation
The team removed the old materials, power-washed the area, and meticulously detailed problem areas, particularly around stirrups for decking support and long-standing leak zones. Specific attention was given to the tradic roofing, which had recurring leaks due to high winds forcing water under flashings.
Waterproofing Solution
They used liquid rubber and a top coat for full coverage, creating a solid waterproof seal with clean lines for application.
Protection Layer Installation
To prevent membrane damage from shrinkage or displacement, they laid down *Armour Blue*—a peel-and-stick protection sheet over the membrane. This layer, semi-adherent, can be removed if needed and re-applied, preventing membrane tearing issues common with synthetic grass.
Final Structure
After the waterproofing and protection layer, decking and synthetic grass were installed on either side of the rooftop, with photos pending for further review.
