Belzona® 4141 (Magma Build)

Belzona® 4181 (Magma AR Screed)

Problem: The system required a sump for the waste water to pass through, and having drilled it from solid concrete, it had to be lined and sealed.
Photograph Descriptions
  1. Sump drilled out 
  2. Cutting inlet and outlet channels to laundry drain 
  3. Walls rebuilt with Belzona® 4141 and paving slab installed 
  4. Sump screeded with Belzona® 4181
Application Situation
The hospital decided to recover heat from the waste water in their laundry by installing a heat exchanger.
Application Method
Application carried out in accordance with modified version of System Leaflet TCC-9. First a new base to the sump was created using a paving slab. Belzona® 4141 was applied to fill the damage caused by the drill cores. Belzona® 4181 was then screeded over the entire surface to provide heat resistance.
Belzona Facts
Prior to the Belzona solution they had been looking at trying to cement line then insert a stainless steel box liner.
