Certifications and accreditations

Expert body for consultation, expert reports and site managment for construction and infrastructure projects in mining areas, approved by the German mining authorities.

Expert body for consultation and expert reports on preventative and defensive fire protection measures and the investigation of fire damage and fire incidents with special circumstances, approved by the German mining authorities.

The DMT Expert Body for Ground Movement provides extensive services for measuring, forecasting and evaluating ground motion, executed by its own publicly appointed experts. The expert body operates monitoring networks worldwide and acts as an independent expert witness for authorities, private individuals and customers from industries such as mining and tunnel building, civil engineering and infrastructure.

Its specialist applications include subsidence and deformation forecasting, terrestrial and satellite based radar-interferometry measurements, state of the art tachymeter monitoring techniques, 3D laser scanning and high-precision GNSS measurements – also for offshore projects and areas prone to explosion hazards. Furthermore, the expert body provides high-end solutions for all kinds of geodetic and geomonitoring work using its own specially designed monitoring software DMT SAFEGUARD. 

It is the job of the body's experienced expert witnesses to get to the bottom of what are often very complex causes of ground movement, in order to determine and subsequently minimise any resulting risk to people or property. Their combined expertise ranges from the fields of surveying, mining, civil engineering, applied geology, hydrology, site remediation and construction engineering.

Our services

• Consultation, expert witness reports and statements, research
• Planning, execution and evaluation of complex geodetic and geotechnical surveys for monitoring the earth's surface, slopes and hillsides or buildings, in the construction and civil engineering and mining industries.
• The latest industrial measuring technology in the fields of GNSS, total station, laser scanning, radar interferometry and geotechnical sensors – above or underground, on or offshore.
• Earth and rock movement forecasts for the mining, oil & gas and caverning industries – subsidence and deformation modellling using reputable techniques.
• Expert reports on mining-related damage and analysis of the effects ground movement has at the surface, on streets and buildings, pipelines and water balance.
• Creation of customer-specific geo-databases and GIS applications – also internet based.
• We set up complex monitoring systems with warning functions based on our in-house software DMT SAFEGUARD for real-time transmission, evaluation, online accessibility and long-term archiving of monitoring data.
