The emission class requirements for machines used in ground investigation are becoming increasingly stringent, and the pressure to work in an environmentally friendly manner is growing. Geomachine’s response to this challenge is the fully electric GMe100 drill rig.
The emissions of diesel-powered work machines have begun to be restricted, especially in densely built urban areas. For example, in Oslo, their use is no longer permitted. Efforts to reduce emissions are also evident in public tenders organized by cities, where emission class requirements are stricter than before, even if emissions are not yet legally regulated in the tendering area.
In the world of ground investigation, just like in technological development in general today, the trend is towards electrification. New product innovations are continually being introduced under this theme. Geomachine is also actively developing products to meet changes and expectations in its operating environment. The latest example of this is the fully electric GMe100 ground investigation rig.
New product innovations are created in collaboration with customers
Geomachine’s Chief Technology Officer, Vesa-Matti Salminen, explains that the GMe100 ground investigation rig was developed based on market needs. “When the requirement for zero-emission operation was enforced in Oslo, Norway, our distributor operating there contacted us. Following discussions and market research, we began developing an electrically powered drill rig in 2023.”
The GMe100 drill rig was built on the existing diesel-powered GM100 platform. It retains the same functionalities and usability as its diesel-powered twin. The machine’s operations remain hydraulic, but power generation in this rig is fully electric.
The length of Geomachine’s product development process varies depending on whether it involves a completely new product innovation or the further development of an existing product. The journey of the GMe100 drill rig from the drawing board to machine delivery took about two years.
When developing a completely new innovation, the product development process does not end at the time of delivery. “Although the machine is ready at delivery, close collaboration with the customer continues in the support phase,” says Geomachine’s Head of Engineering, Juha Sandholm. “We collect customer feedback on the real-world functionality of the machine to make further refinements if needed. Customers who invest in new innovations are industry pioneers. They understand that a finished product can still be refined after deployment and are keen to participate in this stage of product development.”

An electrically powered option for ground investigation
The GMe100 ground investigation rig is suitable for all the same investigation methods as its diesel-powered twin. These include dynamic probing, weight sounding, percussion drilling, casing drilling, spt and dspt testing, cpt and cpt-u testing, and pore pressure drilling. Additionally, it is suitable for groundwater pipe installation and sampling from both hard and soft grounds.
The GMe100 rig is powered by a battery-operated electric motor. Compressed air is supplied via an electric compressor. “During product development, we realized that using an electric compressor improves the efficiency of the fully electric machine, allowing for longer operation on a single battery charge,” says Juha Sandholm. “With a dedicated motor for the compressor, we were able to reduce the size of the machine’s main powertrain motor.”
The battery life of the rig varies depending on the investigation method used, and its capacity can be increased with an additional battery pack if necessary.
Like Geomachine’s equipment in general, the GMe100 is highly intelligent. It features an IQAN control system and GMTracker data logging software. A Cloud version of the logging software is also available, enhancing workflow efficiency, machine maintenance, and project management by connecting all stakeholders in the project’s value chain in real time.
Usability was another key focus in designing the GMe100 rig. This machine includes more storage space than before for the operator’s tools and essential liquids.



Key principles of product development
Vesa-Matti Salminen explains that Geomachine adheres to specific requirements in product development, ensuring that every product meets the highest standards. “We strive for quality in everything we do; our machines must be durable and perform at their best. Our products must also be easy to use. That’s why we aim for minimal differences in usability between models. Workplace safety is another crucial factor, and we continuously develop new solutions to enhance it.”
Geomachine’s customers share a commitment to working with the most reliable and user-friendly machines on the market. But that’s not all. “Our customers also highly value efficient and high-quality customer support. It’s important for them to get assistance from a familiar service representative who knows the machine’s history and features inside out.”
The GMe100 is a product innovation that Geomachine is extremely proud of. “Drawing on our extensive experience, we have successfully built a machine that enables ground investigation with exceptional quality and efficiency—now also in a more environmentally friendly and emission-free manner, meeting today’s demands.”
