PROJECT CASE STUDY

5 Mill Street, Perth

Waterseal installed an approximately 800 m² single-ply TPO recovery membrane overlay to the retained roof at 5 Mill Street, Perth.

THE CHALLENGE

A retained roof requiring a durable recovery system.

The existing roof needed a durable recovery system that could be installed over the retained roof build-up while providing reliable waterproofing across a large commercial area.

THE SOLUTION

A mechanically secured TPO recovery membrane.

Waterseal installed approximately 800 m² of single-ply TPO recovery membrane. The system was mechanically secured, with laps completed using automatic and hand hot-air welding for consistent detailing across the roof.
