CHECKER PLATE ROOF JOINTS SEALED WITH BELZONA
Industry: Chemical & Petrochemical (PETR)
Application: RPA-Roof Problem Areas (RPA)
Substrate: Checker plate steel panels.
Customer Location: Petrochemical Plant, UK
Application Date: 2009
Products:
Belzona 3121 (MR7)
Problem: The checker plate panels were landed on a gasket seal. Unfortunately, the seals for several panels had failed and water was penetrating into the asset. A bigger problem was presented by caustic vapours escaping from the joints during certain production phases. With no planned shutdown imminent, the client was urgently seeking a solution that could be rapidly installed. The site had many flammable materials and so only cold works and minimal preparation would be allowed.

Belzona Facts
Belzona 3121 is a liquid applied emergency roofing material that bonds directly to most substrates. This allows for a very quick application and so minimal downtime was required for this work. In addition, the materials are immediately weatherproof. Whilst the application was originally only intended to be a short term solution, it sealed the panels perfectly for over 2 years until the client finally scheduled the replacement of the seals beneath the roof panels.
