Astra Zenica – Leak Rectification Works


Astra Zenica - Leak Rectification Works

Ongoing leaks were reported reported to a ground floor,  faceted curtain wall screen.

Dortechs Maintenance engineers attended site and conducted investigation works, which included water testing to identify the cause of the leaks. Further intrusive investigations had to take place and a number of ‘weak’ areas were identified, were silicone seals can degraded and EPDM membranes had not been installed correctly.

To resolve the issues with this screen, our glazing refurbishment engineers removed old silicone and poor jointing details and resealed the entire screen. New EDPM membranes decorative cills manufactured and installed.
