Industry: Buildings & Structures (BSTR)

Customer Location: University, Manchester, UK.
Application Date: October 2011
Products:
Belzona® 3131 (WG Membrane)

Application Situation
Courtyard walkway with surface water drain, the source of water ingress into laboratory machine shop below.
Application Method
Application was carried out in accordance with modified versions of Belzona Know-How System Leaflets RPA-6 and RPA-8. The system comprised three coats of Belzona® 3131 with the third coat blinded out with Belzona® 9221 aggregate to improve abrasion resistance and provide positive grip
Belzona Facts
The application was completed within 4 days and has eliminated water ingress. In addition to eliminating the water ingress, by applying a third coat of Belzona® 3131 and blinding out with Belzona® 9221 surefoot aggregate, a positive grip system has been created which is both practical in reducing slip risk and pleasing to the eye. The alternative could have been to remove the drain, recut the concrete deck and replace. This would have proved a very lengthy, disruptive and costly procedure with no guarantee of success.
