Whether EWS system, camera inspection or waterjet cutting – we deliver quality that makes a difference over the entire lifetime of your installation.

Consultation – EWS Geothermal Systems

Mr. Geser has been working in the field of drilling and geothermal energy since 1979, building a very large and extensive wealth of experience. This spans single-family home projects through to large-scale installations and international reference projects – from Bavaria to Switzerland, Finland and Kosovo.

Our consulting services include:

Planning and design of EWS systems (geothermal probe systems) – small to large scale
Product consulting: selecting the optimal geothermal probe, probe base, distribution system and manhole for your specific location
Support preparing permit applications
Technical advice on heat pump sizing

Let us advise you – and benefit from this wealth of expertise.

Camera Inspection for Geothermal Probes

Leak Detection & Damage Diagnosis

In case of probe leakages, it is now possible to inspect the individual pipes of geothermal probes – DA32, DA40, DA50 and larger – endoscopically down to a depth of 350 m, using a specialized camera via the exposed probe head, recording simultaneously.

Advantages of Geser camera inspection:

Precise localization of damaged areas using simultaneous depth measurement
Significantly improved image quality compared to standard cameras
Determination of cause of damage based on damage pattern (manufacturing fault, mechanical damage, corrosion)
Fast decision basis for repair or probe replacement

In 2017, Geser Erdwärme performed the first camera inspection of a geothermal probe exceeding 300 m depth in Switzerland, using a specialized camera system.

Waterjet Cutting

Precision Cutting for Geothermal and Beyond

Geser operates a Mach 3b with dynamic waterjet, cutting pressure 4,150 bar, working area 2 × 4 m – one of the most precise cutting technologies for demanding materials.

Standard waterjet cutting products:

Preventer seals (for borehole closures)
Wellhead seals
Special seals in various designs: top wall, annular space seal, wear rubber

On request, we also cut:

Steel, stainless steel, aluminium
Marble, stone, ceramic
Glass (including coated)
Composites, plastics, rubber

Advantage: Material-gentle cutting – no heat-affected zone, no material loss from heat, suitable for sensitive materials.
