600 M2 Flat Roof Waterproofed With Belzona



Sugar (SUGR)



Roof Problem Areas (RPA)


Customer Location:

Wastewater treatment plant, Rosenheim, Germany


Application Date:

August 2010


Application Situation:

Leaking 600 m2 flat roof



Melt water had regularly leaked through the roof into the hall below as a result of the snow-prone winters in this region.



Belzona® 3111 (Flexible Membrane)



Roofing felt, steel


Application Method:

Application carried out in accordance with Belzona Know-How System Leaflets RPA-1, 6, 7 & 8.


Belzona Facts:

The application took only 3 days to complete. Despite the harsh and snowy winter of 2010/2011, the roof is still completely watertight today and the customer is very satisfied with the result. In contrast to commonly used weatherproofing materials, the cold applied, microporous Belzona system allowed for seamless encapsulation of the roof, adapting to the complex, irregular roof contours as well as roof movements.
