Industry:

Water / Wastewater (WATR)

 
 

Application:

Floor Problem Areas (FPA)

 
 

Customer Location:

County wastewater plant in Northern Florida, U.S.A.

 
 

Application Date:

February 1995

 
 

Application Situation:

Spalled concrete at railings along a platform perimeter above an aeration tank.

 
 

Problem:

Deteriorated concrete around the base of the handrail posts raised safety concerns.

 
 

Products:

Belzona® 4111 (Magma Quartz)

 

Substrate:

Concrete

 
 

Application Method:

The application was carried out in accordance with Belzona Know-How System Leaflet FPA-10.

 
 

Belzona Facts:

Patching the concrete did not work, since the old and new concrete did not bond well. This allows water to migrate through the repair, causing the same deterioration of the concrete as before. Replacing the slab would cost thousands of dollars as well as the interruption of the aeration tank process.
