The Comacchio 305 is a powerful and versatile drilling rig, ideal for a wide range of ground investigation projects. Known for its reliability, precision, and robust performance, it is capable of both rotary and percussive drilling, making it suitable for varied and challenging ground conditions.
The 305 is compatible with the Geobore S drilling system, allowing for high-quality core recovery in difficult formations—ideal for geotechnical and environmental investigations requiring undisturbed sampling. Despite its power, the Comacchio 305 remains compact and highly maneuverable, making it perfect for use in urban, restricted-access, or sensitive environments.
The Comacchio 205 is a compact and efficient drilling rig, ideal for geotechnical, environmental, and site investigation work. Its lightweight design makes it perfect for confined spaces, restricted access areas, and urban sites.
Capable of both rotary and percussive drilling, the 205 delivers reliable performance and accurate sampling in a range of ground conditions. It can also be configured for window sampling, coring, and auger drilling, offering great versatility on site.
Easy to transport and operate, the Comacchio 205 is a trusted choice for projects requiring precision and minimal disruption.

Our LGP (Low Ground Pressure) Pressure Rig is specifically designed for use on soft, sensitive, or inaccessible terrain where traditional rigs may struggle. With its wide tracks and reduced ground pressure, it can operate effectively on sites such as marshland, peat, riverbanks, and agricultural land—minimising disturbance and avoiding ground damage.
Ideal for Cable Percussion, Rotary Drilling, or Site Investigation work, the LGP rig ensures safe and efficient access to challenging locations while maintaining high performance and stability.DMW Drilling are industry experts in cable percussive drilling and site investigation. We are striving to become a nationwide leader with the quality of our work and cost effective solutions.
