    I'm planning a basement which sits in the hillside and is open at the front. However the structural engineer keeps designing in cold bridges between the basement and the timber frame. He now tells me the basement wall will have to be stepped internally and the ground bearing pressure precludes the use of insulation outside the basement walls or under the slab.

    I thought the EPS 300 would be more than adequate, especially as Passive Houses are built on a raft of insulation.

    As you don’t need to support brick outside of the timber frame, I don’t see why you can’t have external insulation for the basement, with the timber frame just sitting on top of the basement wall.

    The architect had specified external insulation for the basement walls and slab that then continued and link with EWI on the outside the Timber frame. He's meeting with the SE today to try to better understand what his problem is with insulation under the slab and outside the basement walls.

    The meeting between the architect and the structural engineer went well and insulated raft foundation is back on track. Why is it that in Sweden the majority of foundations use this approach, yet in the UK it's seen as a novel approach?

    Because it is considered 'new', and the UK construction industry does not do 'new'.....:sad:
    However, I have clients that have built ins. rafts with no issues from SEs or warranty/insurance co's, so perhaps things are getting better... :neutral:

    Clay!

    When you are building on clay you have to do down a long way, then backfill with MOT if you wish to use a raft foundation. Lots of the UK including London is on clay.
