    Hi all, in the process of creating a patio.

    as such i had to remove my existing concrete surface. i was expecting to find a soil layer, but turns out its predominatley rubble/ bits of crushed brick and aggregate etc.

    now my question, rather than buying mot 1 can i use this crushed bricks/ rubble instead of mot1 or failing this can i even put the rubble under the mot 1, say 30mm rubble/crushed brick and 70mm mot1 and wacker plate down

    it saves me hassle of having to clear out all little bits of rubble.

    i have attached a picture to give a idea of the size of the pieces of rubble on average which are about 2-3 inches i would say

    zuber ali, good evening.

    If the area of concrete surface you have removed was not breaking up, forming holes and if not laid to a fall retaining pools of rain water then that in itself would tend to indicate that the sub base you have now exposed is it for purpose again.

    Your proposal as detailed above should work fine.

    Ken.

    You can reuse that if you are prepared to break it down to small pieces.

    Is there a way to break down to smaller bits. I.e is it more cost effective to hire something to do it or is it cheaper to just Chuck it in a skip and get new mot1

    Sledge hammer then Lump hammer would be the norm if you have time to spare.
