Flood irrigation pipe is made of concrete of which were generally built in 3’ sections. This means every 3’ we have a pipe connecting to one another with a “joint”. The joint is sealed with concrete or mortar mix. As the pipes ages, air pressure + water pressure + use cause these connections to fail. The result is a cracked joint. A ring crack is the result of the same and is generally located in the middle of a pipe or just before the joint. In most cases this is a simple fix that does not require replacement to the existing infrastructure.
