This limitation is easily circumvented by using various membranes, primers,
or mortarbedding systems that are compatible with the substrate.
The process industriesuse liningsystems (membranes) on most substrates
onto whichb rick and tile are installed to ensure total resistance from
aggressive environments encountered in suchapplications as
1. Pickling, plating,a nd galvanizing tanks in the steel and metalworkingi ndustries
2. Absorber towers in sulfuric acid plants
3. Scrubber in flu gas desulfurization applications
4. Floors in wet acid battery and chemical plants
5. Above-grade applications in dairies, food and beverage,and other
processing plants
