I need to seal an existing pipe penetration through a concrete foundation wall from the inside of the building, has anyone had any success in doing this? The seal needs to stop water from coming in and has to be from the inside. Is there a special Link-seal type or a clamp on or a good sure fire trowel on product that is readily available??
Thanks!!
Jim

Oil base great stuff will seal it.
I've seen tar used and concrete to fill the whole and also waterproofed after this and not work, great stuff should do it. Get it at Lowe's

Best solution available on the market in this moment:
