Tanks and Chemical Containment Areas (TCC)

 
 

Customer Location:

Lisbon

 
 

Application Date:

April 2019

 
 

Application Situation:

Repairing and coating of a concrete tank used for storing potable water.

 
 

Problem:

A large concrete tank used for supplying potable water for 3 of the neighboring cities was severally damaged internally. The cracked concrete was causing water to leak out of the external wall of the tank onto the road.

 
 

Products:

Belzona 1161

Belzona 5831

 

Substrate:

Concrete

 
 

Application Method:

The concrete tanks were were pressure washed to get rid of any loose bits of concrete and to clean the tank walls before coating. As parts of the concrete walls were severely cracked, Belzona 1161 was used to fill in the damaged area. Finally Belzona 5831 was chosen to be applied onto the damp concrete as it is a product that cures in immersion.

 
 

Belzona Facts:

As these tanks were providing water to 3 of the neighboring cities, the application team only had 6 hours at a time to carry out the application before the tanks had to start being pumped back up with water again.
