How does Avista assess overall ground stability?

Avista assesses ground stability at the property by examining natural and artificial geological cavities and structures that may increase the local potential for subsidence. Mining hazards, sinkholes and other natural cavities, and the potential for previous holes in the land to have been filled in with materials that are not structurally sound (e.g. in the case of previous landfill sites) are all considered. Sensible precautions and next steps are recommended, so that you are able to inform your client effectively.
