The inclusions of resin give the volume of soil an overall improvement which depends both on the mechanical characteristics and on the swelling pressure and therefore on the degree of expansion of the resin. Generally the resin injection is interrupted when the laser receivers anchored to the building register a very slight lifting of the structure, in the order of tenths of a millimeter.
Lifting does not entail any risk to the structure. The signal provided by the receivers indicates that the foundation soil has reached a degree of compression and thickening such as to allow to counteract not only the tensions deriving from the overlying load, but also those, much greater, which develop when lifting and installing Structural Insulated Panels.
In every intervention geotechnical tests are performed on site before and after the injections to measure the improvement achieved. The intervention is rapid and immediately effective.
