A Basement impact assessment (BIA) will include a phase 1 desk study to verify the site's history and explore hydro-geological conditions and surface flood risk. The basement impact assessment (BIA) takes care of the geological conditions of the area and other potential risks such as drainage, flooding, and groundwater quality. Basement changes can add valuable space to your property, but always ensure that the proposed basement development is appropriate. Earth Environmental & Geotechnical provides a complete Basement Impact Assessments report (BIA) to support your planning application.
