BELZONA REJUVINATES AGED ASPHALT ROOF

KHIA ID: 6117
Industry: Power (POWR)
Application: RPA-Roof Problem Areas (RPA)
Substrate: Asphalt.
Customer Location: Power Station, Teesside, UK
Application Date: 2016
Products:

Belzona 3111 (Flexible Membrane)

Problem: This aged asphalt roof was cracked in many places and there were several large ponding areas where water would not fall to drains. A much larger pitched roof above it also drained directly onto the asphalt, resulting the roof having to accommodate about six times more water than it was designed for. These problems had led to several leaks being identified in the plant rooms beneath and essential equipment was at risk of being ruined. Environmental and safety considerations mean the client preferred a water based system.

Belzona Facts
The Belzona 3111 is a water based flexible material and has a BBA certificate with an assumed working life of 25 years. In addition, the materials are all cold applied, which was ideal for this site where all hot works are generally prohibited. As the membrane is lightweight, it can be applied directly onto the existing substrates, with no need to remove and renew the asphalt, which in turn greatly reduced the contract costs. The client was delighted with the results and work on further roofs around the site continues.
