    Diagonal Drain in footing

    Hi everyone, Completed the dig on a 3m single-storey extension today and came across a drain that runs a way we weren’t expecting. Seems to serve as a rainwater waste but not too sure if that’s all it is as there’s another clay pipe behind it that seems to run down (done my best to draw it in...

    Core drilling near footing

    I want to core drill through the cavity wall, underground, for a soil pipe. Due to the depth and location of the existing outside drains it will be very close to the footing, practically resting on it. It will need to be about a 150 mm opening. Is this a concern for structural stability? DIY-able?

    Hey all. I'm in the process of tearing down part of my building that was not on a slab, I'm not looking to spend a fortune to pour a new slab so my plan is to just pour footings and put a floor on them.

    Step onto patio

    Hi all, I'm doing a 2m wide patio around a new extension. There is a 5m wide bifold which needs a 100mm step down onto the finished level of the patio. I have put down the mot and have to compact it, but I'm wondering about footings for the step. Pavingexpert says you can lay brick and flag...
