Re: Leaky pipes under slab....
Sun, March 2, 2008 - 4:17 PMEpoxy what ? it's under slab. Repairs are bandaids, and when the pipe that evadently is going bad for what ever reason, starts to leak 3 ft from the last bandaid......etc. Repair has it's place, but in a sinerio like this, it's a maj. pain in the ass to tear out concret to rep. multiple leaks, when you can run new lines ( over head ) and be done with it, forever. -

Sun, March 2, 2008 - 7:11 PMEpoxy is considered better than repiping. Or so they say. See link www.aceduraflo.com

Re: Leaky pipes under slab....
Mon, March 3, 2008 - 6:59 AMI took " repair with epoxy" to mean applied to the outside of the pipe with a patch. I havn't heard of this system. It does seem like it should do as promised. I would check out the company and make sure they are lagit, and will be around to honor that guarantee . I would also ask for a guar. concerning the water pressure. -

Just a few thoughts.
It's not clear to me whether your under slab leaks are related to radiant heating, water supply, or waste piping, though my first guess would be radiant heating. If I'm right, the "pipe lining" solution isn't likely to work for two reasons:
1) Because that's not part of the "pipe lining" folks claims
2) Because the piping system for radiant heat uses different materials than the other
two alternatives.
Also, If it's water supply you're dealing with it may be cheaper to abandon the leaky pipes and run new piping above slab. -

Mon, March 3, 2008 - 2:24 PMAre talking about "trenchless" pipe relining? It's a tried and true alternative for sewer main replacement/repair.
I don't know what your plumbing problems are. This is not a do it yerself thingie.
How old is your slab?
If it is a cable tensioned slab, I don't think cutting into it is an option. I'd definitely hire a pro to consult for this job.

Fri, May 9, 2008 - 4:49 PMMany times epoxy can last 50 years. The way I look at it if it lasts 25 new technology will be out then anyway.
Check out www.pipeproblems.com/ all they do is talk about epoxy pipe lining.

Sat, May 10, 2008 - 7:27 AMRead that 25 year guarantee very carefully and make sure that the company will be there in 25 years.

Re: Leaky pipes under slab....
Sat, May 10, 2008 - 11:21 AMfirst off, there is just not enough info to give you an informed comment. how big is the slab? where is the slab located? what kind of pipes do you have? what is the piping for? what makes you think that there is a leak under the slab? that said, i am not too fond of fix-it's such as these. while the rising cost of copper has made replacing pipes rather costly, if properly installed, they should pretty much outlast your life in the home. at least that has been my experience years in construction.

Re: Leaky pipes under slab....
Wed, May 28, 2008 - 8:31 AMI’d recommend that you contact a dealer or installer in your area. Epoxy may be a suitable solution but the type of failures and the size of the leaks need to be confirmed. Warranties vary by different contractors in different parts of the country. The cost of a lining installation is typically less money then a repipe, it lasts longer, its safer and there is considerably less disruption in repairing your home. Also, you should make sure the epoxy is "ANSI/NSF Standard 61 certified".
