Waterproofing penetrations

2407 21
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?

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.. :eek::eek:
