Description

In the DOV database, any observation of soil layers is a borehole. With most drills, a hole is made in the subsurface with a drilling device to be able to describe the different soil layers. On the basis of a bore you get an image of the material in the subsurface with increasing depth. Depending on the purpose for which the drilling is placed, a suitable drilling method will be used. Drillings are placed for exploratory soil research, sampling of the sediment and/or groundwater, determination of soil physical parameters, environmental hygiene research,... Depending on the depth, type of material, and whether or not drilling to below the groundwater table can be chosen from several systems for manual or machine drilling. The soil material that is released can be used to create a profile of the subsoil or to take soil samples from it to carry out further analyses. It is often the intention to build a well so that water can be extracted (see also groundwater monitoring network and groundwater permits). Sometimes drilling is carried out to determine a number of geotechnical characteristics or to carry out scientific research. Superficial observations of the subsurface are also called boreholes. Especially around 1900, a number of geologists often described the superficial layers. In the database there are several boreholes with a depth of 0 meters. These are mainly road cuts or visible lithological features along the surface.
