Bedrock Fracturing Survey
GTK provides high-quality research data on bedrock fracturing and the location and characteristics of fractures and fault systems. Data on bedrock fracturing is particularly important in rock and tunnel engineering, bedrock storage solutions, and disposal site studies involving geothermal energy and nuclear energy.
Construction is more affordable on intact bedrock
Choosing a safe location
Finland’s most comprehensive research service
Data on bedrock fracturing enables underground disposal
The purpose of bedrock fracturing surveys is to avoid building in challenging locations where work would be prolonged, costs would go up, and the risks associated with the construction work would increase. Moreover, the service is designed to prevent work carried out at bedrock sites, affecting the groundwater in the area. At the same time, the aim is to mitigate the risk of process waters migrating in the bedrock as a result of rock construction or disposal site studies.
A bedrock fracturing survey may be conducted in the context of, for example, underground storage of hydrogen or energy storage, construction of a subway tunnel, geothermal energy production, nuclear waste disposal, or site selection for a nuclear power plant.
The service includes different sections that are implemented according to each customer’s individual needs.
As a rule, a preliminary study is conducted to locate potential fracture or fault zones, which often appear on maps as linear structures. In addition, intact bedrock areas are located on the basis of existing data. The data may consist of GTK’s research data as well as the customer’s own reports, such as results from bedrock drilling.
Based on the preliminary study, targeted field studies and geophysical measurements are carried out, as necessary. Consequently, the most suitable drilling sites are selected for further investigations.
Once all the studies have been completed, an assessment is made to determine the impacts of the bedrock structures on the planned rock construction activities or the suitability of the disposal site. Moreover, survey data on bedrock fractioning may also be collected for the purposes of environmental impact assessments (EIA) and other permit reports.
GTK’s service produces regional survey data
At GTK, larger regional scale surveys are also carried out to define shear zones, fault zones and fracture systems.. The survey can be used to identify larger intact areas, which may be useful in the planning of land use for regional projects. However, the service is not suitable for site-specific examinations in construction projects.
