Common methods used in industry to protect valves in below ground applications: a) Build a concrete chamber to have the valve secured. In this method the valve requires minimum protection of painting. b) Bury the valve directly in soil, however minimum protection requirement should be such as: FILLER Denso Profiling Mastic - A self-supporting mastic containing beads of closed cell cellular polymer. Used as a flexible caulking and filler material for molding around irregular shaped fittings such as flanged joints and valves.
