Training according to DVGW 120-2: Automatic sealing control of geothermal drilling using the CEM-Trakker on 27th Jan. 2017
The most discussed topic in the geothermal engergy indistry is the "automatic sealing control". The training will introduce the topic and provide backgroundknowledge regarding drilling, grouting, building materials and underground in the context of automatic sealing control. Moreover, the use of the CEM-Trakker is shown and trained with real data and real hardware, such that the use of the system s understood and applied correctly. Further information and the registration (in German) can be found here.

Landfill Site Ruppenmanklitz - Detailed Investigation
Technical project support and construction supervision during percussion drillings and the installation of 3 temporary groundwater monitoring wells in cooperation with GEO4 (see picture). During the exploratory work soil, soil air, and strata water samples were taken by the GEO4 Team and subsequently analysed in the lab. Next steps: key date measurements, potentially groundwater sampling, evaluation of the results and risk evaluation regarding the soil-groundwater and soil-soil air-human dynamic pathways.

New Directive on State-founded Support of Ground-coupled Heat Pumps
From April 1st, 2015 new guidelines for the state-founded support of ground-coupled heat pumps come into effect. The compilation provided by the german heat pump association (Bundesverband Wärmepumpe, bwp) giving an overview, can be found here. The manifold objects of funding and bonuses can be confusing at first sight. To support you in getting the most out of the new directive, we offer you our qualified and professional guidance. We are looking forward to your inquiries!
