Kalsi Underground Drainage Systems are designed for use in gravity drainage and sewerage applications, up to a depth of 10m.

• Kalsi Socketed Underground Pipe combines reliable connections with the latest in blown end technology.
• A plastic circular insert holds the rubber seal in place during transit and also provides an ideal connection for jointing.
• All Kalsi underground fittings utilise seal and snap technology, avoiding sharp edges and allowing for an easy fit connection. The seal is double ribbed, whilst the sockets incorporate a recess that provides space for the rubber seal to locate as the pipe is inserted.
