Clay Pipe Failure
Clay Pipe Failure
(OP)
I am looking for information on sewer clay pipe failure. I am working on a sewer rehabilitation project that will involve removing and replacing 50-60 year old clay pipe that has been described as having longitudinal and circumferential cracking. I suspect that the cracking is caused by tree roots. I am looking for testing that has been done to determine what kind of pressure tree roots can exert to crack and displace 6"-8" clay pipe and cause the cracking noted above. I would be also interested in the type of cracking that results from soil and traffic loading. Thanks!

Check into the "Clay Pipe Engineering Manual".
Hope this helps.

RE: Clay Pipe Failure
Roots start out getting throught he joint. thyey increase in size over time and can break out the joint. They can crush a pipe but this doesn't happen as often in the streets, ussually in ayard nearer to the tree.

When you have a root problem, it is ususally visible via CCTV.
Depending upon the total footage of pipe in question, some type of trenchless technology may be a cost effective rehabilitation option.
