Application Date:

1987

Problem:

Deterioration of original felt finish had allowed water ingress into the roof deck. In particular the roof insulation had become saturated. Traditional repairs had not been successful.

 
 

Products:

Belzona® 3111 (Flexible Membrane)

 

Substrate:

Felt

 
 

Application Method:

Application was carried out in accordance with Belzona System Leaflets RPA-6, RPA-8, and RPA-10. Breather vents were also installed to allow the insulation to dry out.

 
 

Belzona Facts:

Use of Belzona® 3111 has allowed long term weatherproofing to be achieved with minimal disruption to the building. The original roof covering did not need to be stripped off and occupation of the top floors continued unhindered. Inspected in 1996, the roof was 100% watertight.
