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.

"Thanks to the advanced nature of Geobearss solutions, buildings dont always have to be lifted to be repaired. In some cases, a number of very small sized holes can permit geopolymer resins to be injected through floor coverings and finishings should lifting not be a feasible or necessary option."

Any experiences of this?

Is there a tool to measure the slope or position of the walls very accurately and then again a year later?
