Guidance: HS2 ground investigations: a non-technical guide

Ground investigation is the examination and study of the soil, rock and groundwater at the site of planned infrastructure and building projects.

A number of survey methods are used to obtain samples, including drilling boreholes, excavating pits or digging by hand around utility pipelines. Laboratory tests are carried out on many of the samples to supplement the information gathered on site. The aim is to provide data before the design and construction processes begin and to discover the properties - especially the strength - of the soils and rocks in a particular place, and the nature of the groundwater.

This guide provides information on the different types of ground investigations HS2 Ltd may need to undertake at sites along the HS2 line of route, as well as answering some of the questions you may have about ground investigations and how and why they will be undertaken for HS2.
