Water Repellent Belzona® Treatment For Swimming Pool Walls

 
 

Industry:

Local Authorities & Municipalities (LOMU)

 
 

Application:

Wall Problem Areas (WPA)

 
 

Customer Location:

Local Council Swimming Pool, Gloucestershire, UK

 
 

Application Date:

February 2008

 
 

Application Situation:

Exterior walls of council swimming pool.

 
 

Problem:

Water penetration into the building fascia was causing salt to be washed out of the bricks, visibly discolouring the wall and leaving the swimming pool looking worn and tired.

 
 

Products:

Belzona 5122 (Clear Cladding)

 

Substrate:

Concrete

 
 

Application Method:

The application was carried out in accordance with Belzona Know-How System Leaflet WPA-8. A number of blasting systems were used in the attempt to remove the salt. The system that provided the best results was a system used in the marine industry to clean off the undersides of boats, called the Farrow System (high pressure water/sand blast system). Once the salt had been removed, Belzona 5122 was applied by the council's internal maintenance team via a pump up hand spraying system and a brush application around details, such as pipes, windows and doors.

 
 

Belzona Facts:

The application was completed over the course of 2 days. The swimming pool was kept in service throughout the maintenance work. Blasting was carried out before opening hours and the water repellent treatment was carried out in 2 stages to ensure minimum disruption to the public. The system has lasted the test of time for the council and they are more than happy with the results. No salts or staining on the concrete block walls is visible even after 7 years.
