Underpinning walls in basement.

[ringi]

I am likely to need to get the internal “spine wall� in a basement underpinned as it just sits on the sand subsoil with no foundations, the bottom of the wall is at the same depth as a quarry tile floor that only has about 1 inch of mortar under it.

I may also need to get the outside wall of the property under pinned as their foundations don’t go much below the basement floor level.

Just what is involved in doing this work? Is this the type of job that I should get a grounds work company to do rather than normal builders? (E.g do I split it from the contract for the loft conversion.)
