Foundation movement joints?

    Hi, I have received my construction drawings for a 2200 sq ft bungalow. This is an L shaped house and block cavity build.

    The structural drawings show the foundation is broken into three seperate sections which are separated by a 20mm movement joint with the necessary reinforcement and depth at the edge.

    Is this a normal foundation make up? It also states to 'continue the movement joints up through the superstructure', but there are cavity walls running across these joints!?

    Thank for any help!

    Who did your construction drawings? Was there a structural engineer involved?

    Yes, my Architect got them drawn up by a structural Engineer. The house is half pitch roof and half mono pitch, but there are two movement joints.
    I will ring the Engineer on this on Monday but I would just like to know a bit on why they are needed and if anyone has any experience on having movement joints up through their cavity walls.

    Good plan!

    There is obvioulsy a reason for the joints. Could be ground conditions or some other reason. Suggest you ask the engineer (and architect) first. I'm sure both or either will be more than happy to explain it you.
