Industry:

Buildings & Structures (BSTR)

 
 

Application:

Wall Problem Areas (WPA)

 
 

Customer Location:

Office building, Manchester, UK

 
 

Application Date:

August 2015

 
 

Application Situation:

Large office building with associated car park.

 
 

Problem:

Chunks of concrete were falling from various cracked and spalled areas of the building façade, causing concern for the public below.

 
 

Products:

Belzona 4141 (Magma-Build)

 

Substrate:

Red Brick and concrete

 
 

Application Method:

The application was undertaken in accordance with Belzona System Leaflet WPA-4. In order to access exterior areas high up on the building, a Spider MEWP (Mobile Elevating Work Platform) was used. As the building’s façade is made of red brick, a powder tint was added to the Belzona 4141, ensuring the system blended in with the surrounding substrate and provided an aesthetic finish. Temporary formers were used to support the Belzona material during application and to assist in reforming edge details.

 
 

Belzona Facts:

The extensive repair work was completed in three months, (working weekends only), a small amount of time considering over 300 repair and protection applications were carried out.
