Office Balcony Roof Repaired With Belzona®



Buildings & Structures (BSTR)



Tanks and Chemical Containment Areas (TCC)


Customer Location:

Office building, Glasgow, Scotland


Application Date:

November 2013


Application Situation:

A set of roof balconies had developed leaks, particularly around joints, seams and flashings.



There were different substrates used for the roof & flashing, including felt and lead. There were also handrails & bolts to be removed that left gaps that had to be waterproofed. In particular, the balconies had developed ponding water,which, due to  being north facing rarely dried up.



Belzona 3131 (WG Membrane)



Felt & lead


Application Method:

Application was carried out in accordance with Belzona System Leaflets RPA-1, RPA-6 and RPA-8.


Belzona Facts:

Coating the roof rather than removing the felt substrate saved the customer time & money and provided a seamless system able to cope with the regularly ponding water.
