Belzona® Solves Leaking School Roofs

 
 

Industry:

Buildings & Structures (BSTR)

 
 

Application:

Roof Problem Areas (RPA)

 
 

Customer Location:

Prestigious boarding school in the south west of England

 
 

Application Date:

August 2012

 
 

Application Situation:

School had been suffering water ingress via lead flashings & gutters on four boarding house roofs.

 
 

Problem:

Asphalt, used to replace lead flashings in gutters, had failed allowing water ingress into the four boarding house buildings. Several attempts to repair the asphalt had failed. The school required a solution to be cold applied so allowing them to remain in use. 

 
 

Products:

Belzona® 3131 (WG Membrane)

 

Substrate:

Asphalt, Slate, lead & Stone

 
 

Application Method:

The application was carried out in accordance with modified versions of Belzona Know-How System Leaflets RPA-6 & RPA-8.

 
 

Belzona Facts:

The Belzona solution was carried out over two weeks. Belzona® 3131 bonding to all of the substrates meant that the old asphalt did not require complete removal which could have led to damage to the slate tiles. The results were a complete success allowing the school continued use of the boarding houses. To replace the damaged asphalt with traditional lead work would have been over budget & involved hot work stopping the use of the boarding houses & the summer school events.
