    Hello

    I have a hole in the ground. The four walls and floor are cemented in. How would you stop water seeping in?

    can you seal the cement with bonding agent, or would plastering do it?

    thanks

    Are you basically talking about waterproofing a basement?

    Hello

    No think of a sump hole in the ground

    I want to waterproof the cement wall of the sump hole.

    thanks

    The walls aren't cement.
    Cement is an incredient in concrete and mortar.

    I imagine you are refering to concrete walls here. It would of been easier to do it at the start with a membrane but I suppose applying a bituminous coat now would seal it sufficiently

    I would use either a cementitious waterproofing slurry (2-3 coats) or, as Mellor said, a bituminous liquid waterproofer. Cement based is less messy.
