A guy down the street recently had foundation repair. He told me that during the initial inspection, the they put a device in the middle of the house. Attached to it were tubes with fluid in them that they extended out to all the other rooms. They used this thing to develop a contour map of the foundation telling them I suppose where piers might need to go. Can anyone tell me what this tool is called and how it works?
