Penetron can penetrate a substantial distance ( up to a metre from mem) and completely seal blocks internal structure. Meaning no wall full of water if done correctly.

    I think you missed the point you are only addressing the symptoms not the cause. You could just be moving the issue to another area.

    That's exactly my point... if you had a leaky roof or a leaky second story where the water is running down inside the blocks, after it's so well sealed, it can't get out.

    I agree too, you should first eliminate the possibility water is entering from elsewhere like a leaky roof etc first.

    Most basement block leaks are from moisture externally entering outside of blocks thru poor or failed tanking etc.
    Typically to remedy these you often need dig up the dirt against house blocks. This gets expensive and time consuming and can be not practicle if you have gardens etc in place.

    or maybe an Architect?

    I would go an experienced builder or waterproof specialist who has dealt with the issue numerous times previously myself.
