Subsidence measurements ?

Having watched many programs of Homes under the Hammer, plus Kirst and Phil, the message seems to be, if a crack on an outside wall also occurs on an internal wall in the same spot, or if it goes diagonally down a wall, it could be serious.

If just a door frame is moving, could it be the slab at fault ?. Lots of houses were built using power station ash as part of the concrete used to pour slabs and these can chemically interact with the soil.

Any trees nearby ?, or evidence of sinking, tilting paths that might indicate a broken drain ?.

there's a right angle sofa at the downhill corner, drunks gravitate to it..

A surveyor came round last week and said we could inject foam under the house.

The geobear website says its wonderful, but they would, wouldnt they.

Any experiences of this?

No experience but sounds iffy to me. Is the building still moving? Quite often they move and then stop. It's important to monitor what's happening. Did you glue glass telltales over the cracks?

You need to get advice from other sources. You need to speak to previous customers of this firm. Also check with your neighbours if they have any history and the cures.
