The drilling of holes has always been one of the most important tasks of mankind. They provide a rule for the vital supplies to people and their environment with clean water.
Experience, modern technology, highly trained staff and a spirit of trust interplay between specialized firms, construction managers and clients are the essential prerequisites for the success and customer satisfaction.
E + M is a valued partner, whether for water development by municipalities, Baths, industrial or for research drilling and soil investigations.
This experience and expertise is essential, even the most difficult
to solve drilling and well engineering problems. With our decades of
Experience, we have this expertise - for the benefit of our customers.
The number one food is our number 1.
The development of water resources - be it "normal" ground water, a precious mineral water or water for geothermal plants - is one of our core competencies.
Drilling methods
Drilling with reverse circulation: Based on the principle of the lift pump method is the classic technique for water wells. With pressed-air is here along with the core slug of Bohrspülwassers removed from the hole. The E + M technique allows in consolidated and unconsolidated rock drilling depth of 50 m, 100 m or 200 m and deeper. The wells are executed with expansion diameters 200-500 mm (DN 200 - DN 500).
Flush drilling (rotary drilling): Functional characteristics is the Spülflüssigkeitskreislauf which continuously carries the cuttings up. This technique is suitable for drilling in consolidated and unconsolidated rock.
Shallow drilling large diameter: This is to drill holes with a diameter of up to 1,800 mm in the soft ground. They are executed as dry drilling with stabilizing tubes.
Geothermal drilling: The utilization of geothermal energy in connection with the installation of geothermal systems are carried out drilling of 50 m to 200 m depth for the installation of geothermal probes.
Diamond drilling: To describe and geotechnical assessment of ground conditions, creating a surface model for Stability and settlement calculations, the geotechnical documentation, etc. are as dry drilling core holes with an intact and undistorted core the right procedure.
Hammer Drilling: drilling hammer with a hammer on the drill pipe to enable the rapid excavation in rock. This technique, which is, for example, groundwater quality monitoring stations for use, can be combined with a directional drilling (drilling with reverse circulation).
Dry drilling: In addition to those already shown results E + M Dry drilling dry drilling by percussion drilling holes and grab as fixed and loose rock.
The mastery of drilling with special needs is one of the special features of the E + M. One example is the deep well with preventer and locking technique. These are special holes to depths of 2,000 m, for example, asphalt, drilling deviated or directional drilling for geothermal and mining equipment, which run through the pressurized ground formations (eg due to gas inclusions). The Preventer and locking technique ensures that the pressurized medium is not leaking from the uncontrolled drilling
