I'm running 2- 21/2 conduits under slab from meter into basement and need to make sure the sleeves are water tight after I run my conduit through. Anyone have a good recommendation for a sealant? Epoxy?

Silicone?

 

[RJEJ84]

I'm no waterproofing or caulking expert. How does silicone hold up in underground damp conditions? I know it holds up fine in climate exposed conditions.

I've used these in the past and they've done a fantastic job

Shoe Goo works wonders from what I have seen.

Geocel sealant. Put some duct tape around the lower 3/4 of the joint until it sets up.

Randym. Where can you get geocel?

Ace Hardware, Fastenal, Walmart, Amazon.

I agree, this is what we use when we can't take a chance it'll leak.

Inert silicone sealant or grey roofing sealent.

The flexicraft won't work. My sleeve is 3" and my conduit is 2.5. So tight the links wouldn't fit. I'll have to go with silicone or roofing sealant.

I have always used spray foam and after it dries give it (3) coats of automotive undercoating...

I never had a failure yet.. :thumbup::thumbup:

In all seriousness how do you have time to do that? I got to get my arse to the next job most of the time so Ill spray foam cavitys and seal with caulk.

I make the time to do the job right and plan on at least half a day...

The last thing I want is a phone call there is water leaking out of the basement electrical box..

I always use hydraulic cement, then cover that with tar on the outside of the foundation.

We used something called "link seals" on a job recently. It's rubber linked together that you can tighten up around a pipe. They worked great.
