Belzona® Rebuilds The Walls Of A Secondary Containment Area

 
 

Industry:

Buildings & Structures (BSTR)

 
 

Application:

Wall Problem Areas (WPA)

 
 

Customer Location:

Cement Plant, Oregon, USA

 
 

Application Date:

September 2015

 
 

Application Situation:

Concrete walls of an ammonia secondary containment area.

 
 

Problem:

Severe cracks and damage in the walls of the ammonia secondary containment due to design issues.

 
 

Products:

Belzona 4111 (Magma-Quartz)

Belzona 4154 (Bulkfill Resin)

Belzona 4911 (Magma TX Conditioner)

 

Substrate:

Concrete and steel rebar

 
 

Application Method:

The damage at the SE corner required cutting out a section of the walls in one area and a simple removal of a small section at the SW corner. A grinder was used to remove oxidation from rebar. Belzona 4911 was applied to the steel rebar and concrete. Form boards were attached to the concrete to create a frame before pouring Belzona 4154. Once cured, the form boards were removed. A grinder was used to remove the gloss off of Belzona 4154, then the surface was wetted with Belzona 4911 to prepare it for the application of Belzona 4111 as a finishing layer.

 
 

Belzona Facts:

Originally the plan called for rebuilding with concrete. When the engineers saw the bond strength of the Belzona 4154 and 4111 they decided Belzona would work much better.
