The drills – two Comacchio boring machines (models GEO305 and GEO405) – are able to excavate boreholes up to 80 metres in depth. They will be used to support intrusive sampling processes for ESG’s clients in the construction and engineering sectors.
As they run on hybrid Tier IV engines and make use of biodegradable hydraulic oil, the boring machines are more environmentally friendly than conventional rigs. This allows them to be operated on projects within designated low-emissions zones, such as in central London. The two drills have already been put to work on high-profile British construction projects in the Capital, including the Thames Tideway Tunnel scheme.
Jim Murphy, managing director, Infrastructure Services, ESG, commented: “Increased investment in large infrastructure projects and residential developments has resulted in growing demand for ground investigation and geotechnical testing services. Having an extensive plant resource to call on is crucial to being able to offer clients a flexible service and respond to their specific needs.
“By adding these two Comacchio boring rigs to our fleet, ESG is in a strong position to continue to offer the highest levels of technical service as the market continues to grow. The new rigs make use of innovative green technology, and this is becoming an increasingly important requirement for clients as environmental restrictions become more widespread.”
ESG’s fleet of rotary drilling rigs are used to support its Infrastructure Services team with UKAS accredited structural analysis and ground investigation services. The company’s professional expertise and extensive laboratory network has established ESG as the UK's leading provider of geotechnical testing services.
