Dry backfill Mixes
WEERULIN has developed the FOR RAM series dry lining mixes for avoiding infiltrations and running behind the bricklaid safety lining. These are high quality alumina- or magnesite-based ceramically bonding products.
The dry lining mixes are easy to process without any further aid. They are simply poured between the brick rings and the safety lining during the bricklaying of the wall and rammed by hand.
The special dry bonding process promotes quick bonding of the product. Unlike resin bondings, this type of bonding is not a health risk.
The special advantage of our WEERULIN dry backfill mixes is their re-usability: The filled lining can remain in the ladle for up to 10 campaigns. The new permanent lining is simply bricked-up before the WEERULIN backfill lining and if there are worn spots, only these need to be relined. Using WEERULIN backfill mixes the brick layers between safety and permanent lining may even be replaced completely. The cost advantages are considerable.
