Phase 2 Membrane Replacement Project

Project Mobilization Date: July 20, 2026
Work Start Date: May 4, 2026 (for emergency repairs) 
Expected completion: December 2026
Primary contractor: Prostar
Engineering design: Strata Engineering

Weather: 10°C, cloudy, intermittent showers
Workers onsite: At least 3

Work done today:

• Water mitigation to reduce water leaking into underground parking
• Polishing of recently exposed concrete slab to prepare it for sealant and new membrane

A quick post to let everyone know: Council is aware of the water leaking into the underground parking with the removal of the remaining old membrane. Council and management are working with Prostar to address the situation ASAP. Prostar was previously aware of this issue.

If you need to move your vehicle, please check with council first, otherwise you may put your vehicle at risk of being towed.

I will post more when I have any updates.

The daily report on work done will be posted shortly.

Below are some shots taken today showing standing pools of water in the courtyard/parking lot area as of today, October 29, 2026:

Phase 2 Membrane Replacement Project

Project Mobilization Date: July 20, 2026
Work Start Date: May 4, 2026 (for emergency repairs) 
Expected completion: December 2026
Primary contractor: Prostar
Engineering design: Strata Engineering

Weather: 11°C, showers and clouds
Workers onsite: At least 2

Work done today:

• The Terminator, a machine that strips membrane and sealant, was used to expose the concrete slab in the central courtyard area and out beyond toward Building 240

Also of note: With the combination of old membrane and sealant being removed and rainy weather, there will be more leaks in the underground parking. If you see an issue of concern, report it to Council: copperstonecouncil@fastmail.com
