Belzona® Resolves Water Ingress Issues In School Corridor Walkway



Buildings & Structures (BSTR)



Roof Problem Areas (RPA)


Customer Location:

Junior School, Chesterfield UK


Application Date:



Application Situation:

Previously open corridor walkways enclosed with UPVC double glazing.



Approximately 8 years prior to the Belzona application the corridor walkways had been enclosed to provide a safe and warm environment for children and staff to travel around the school. Within a couple of years there was water ingress causing dampness to the carpeting and presenting a potential slip risk. The problem was identified as failing sealant between the UPVC panels and the original brick and cement rendered structures. Over the 6 years several attempts were made to reseal but all had failed.



Belzona® 3131 (WG Membrane)



UPVC, Brick, Cement Render


Application Method:

The application was carried out in accordance with a slightly modified version of Belzona Know-How System Leaflet RPA-1


Belzona Facts:

The repairs were carried out over two days in each of the two sections of corridor walkway. The results were a complete success allowing the school to replace the water damaged carpet with new, confident that there would be no further water ingress issues via the Belzona® 3131 protected areas.
