This paper looks at a number of techniques to protect both steel and concrete pipes, internally and externally from corrosive/erosive attack. The use of flexible resin based sealants is discussed as a means of resealing "in situ", joints in socket and spigot pipelines which have become displaced and are subsequently taking in ground water.

The techniques for injection of resins into cracks in concrete structures are identified also typical properties for such resin systems. Details are also given of custom built machines to effect the application and placing of the mentioned systems.
