A Window Of Opportunity For Belzona



Buildings & Structures (BSTR)



Wall Problem Areas (WPA)


Customer Location:

Housing Authority - St. Helens, UK


Application Date:

May 2005


Application Situation:

Concrete Lintels



The concrete lintels had spalled revealing the reinforcement bars underneath. The Housing Association were fitting new windows and wanted repairs carried out quickly and effectively.



Belzona® 4141 (Magma Build)





Application Method:

Application was carried out in accordance with Belzona Know-How System Leaflet WPA-4.


Belzona Facts:

The Belzona solution was chosen as the best way to effect very quick, simple repairs that could be done all at once without the need for formers to be left in place. The ability of Belzona to protect and resist further spalling was also a prime consideration of the client. Alternative was the use of traditional sand/cement mortars that would have looked poor, lacked performance and would have required a much wider time frame to complete. This scheme saw 20 lintels of around 2 metres each completed in under just three days.
