    OK, code requires a "sleeve" around any pipe passing through a concrete basement wall... the gap between pipe and sleeve is to be packed with something flexible to allow for relative movement.

    So two questions:
    1. WHERE was the inspector when my builder passed the copper pipe right through a drilled hole in my basement wall, with no sleeve or packing?

    2. And what do I do now? The hydraulic cement patch I tried doesn't hold- the pipe will always move and break loose. After a good rain, I'll get a few gallons of water on the basement floor.

    I might just chip out the concrete a bit around the pipe, to allow for a thicker packing of caulk... but I wonder if there are any nifty commercial solutions or other tricks for this situation? I certainly don't want to start trenching on the outside...

    A sleeve may not have been a requirement, then.

    Use an elastomeric caulking like Polyseamseal or a urethane.

    Current codes don't apply to things done prior.
    I like urethane caulking.
    I have had excellent results with Vulkem urethane sealants.

    Vulkem and Chem-Calk are often used in storefronts and are a premium commercial grade product.

    Thanks!

    Sleeving has been required since forever. But I did find an example in a local code that allows no sleeve, if boring a hole in an existing wall... but the pipe still has to be free to move longtitudinally, yet sealing is still needed. So, something elastomeric as above, but NOT hydraulic cement.
