link seal works good but you cant install with out a core drilled hole. up here in ny state if a link seal is not used we use hydro cement inside and cement outside. then after cement dry's we use tar to water proof the area we worked on

I'm in the Raleigh Durham Chapel Hill triangle and on water services we use hydraulic cement on the outside of the sleeve to the foundation (inside and outside of the foundation), and pure silicone between the sleeve and the pex.

For main drains exiting the foundation, the guy that usually does our digs will use hydraulic cement from sleeve to foundation surface, and use a 4 x 6 fernco to seal the gap between 4in and sleeve, on the outside of the foundation. It works well and looks very clean.

I don't recall ever failing an inspection for the way water service or main drain pass through the foundation. Durham inspectors are the most finicky, and will fail us for water logged trenches and such if a surprize rain hits over night. As for the penetration through the foundation, like I said, I have not seen one failed for those two methods to date.
