Belzona® Seals Valley Gutters



General Industry (GIND)



Roof Problem Areas (RPA)


Customer Location:

Manufacturing Plant, Scotland


Application Date:

October 2014


Application Situation:

Several valley gutters constructed from cast steel had begun to leak from the joints. These leaks were causing damage to the stored materials below.



Full replacements of the gutter would have caused excessive disruption to the working areas below.



Belzona 3131 (WG Membrane)



Cast iron


Application Method:

The application was carried out in accordance with Belzona Know-How System Leaflet RPA-6.


Belzona Facts:

Belzona 3131, a liquid applied membrane, allowed the applicators to coat the existing substrate without removing large sections of the roof. The Belzona 3131 system is flexible, which has allowed a long lasting repair over the problem joints where competitor materials had failed.
