Products:

Belzona® 1111 (Super Metal)
 

Substrate:

Cast iron

 
 

Application Method:

The manhole seats were roughened and then degreased. Cover plate ends were protected with Duct tape and Belzona® 9411. Belzona® 1111 was used to rebuild the manhole cover seat in accordance with Belzona Know-How System Leaflet GSS-8.

 
 

Belzona Facts:

Belzona® 1111 made a cost effective solution and a perfect fit of the manhole cover in its seat eliminating noise. Conventional replacement method takes time, a lot of work and different material (asphalt, reinforced concrete). The cost savings by using Belzona technology is about 200,00 EUR per manhole.
