Soak Hole & Civil Geotechnical Drilling Services in NZ
DXG are New Zealand-owned soak hole drilling and geotechnical contractors, delivering reliable, cost-effective solutions for subdivisions, stormwater networks, and civil infrastructure projects. Our team provides soak hole installations, water testing, and GPS/MWD-enabled drilling services that give engineers and councils the data they need for design, compliance, and construction.
OVERVIEW
DXG offers a reliable and cost-effective alternative to traditional geotechnical investigation methods through our efficient drilling technologies. By integrating Measured While Drilling (MWD) and GPS data capture, we deliver high-resolution rock data quickly, making it easier for engineers and designers to make informed decisions.
From remote wind farm developments to urban infrastructure, DXG’s drilling services support a wide range of applications, including batter design, pile socket design, soak hole installations, and non-potable water wells.

FAQ
					 What is Measured While Drilling (MWD) and how does it help? 
							
			
			
		
						
				MWD captures real-time data such as penetration rate, torque, and rock hardness as drilling progresses. This reduces the need for slow, expensive coring while still delivering accurate, interpretable geotechnical information.
					 Is this drilling method suitable for design purposes? 
							
			
			
		
						
				Yes. The data produced through DXG’s MWD-enabled drilling can support pile design, socket depth selection, and batter design and modelling, making it valuable for structural and civil engineers particularly when calibrated against core data. It can also quickly identify strata changes for improved resolution or earthworks sequencing and planning.
					 Do you provide soak hole reporting and compliance documentation? 
							
			
			
		
						
				Absolutely. DXG offers water testing and soakage rate analysis with reporting to meet local council and environmental compliance standards.
					 Can DXG support remote or large-scale projects? 
							
			
			
		
						
				Yes. We have the ability to deliver projects in remote wind farm locations, large-scale subdivisions, and multi-site projects.
					 What’s the difference between potable and non-potable water wells? 
							
			
			
		
						
				Non-potable wells are drilled to access water for non-drinking uses such as irrigation, dust control, or washdown facilities. DXG focuses on these applications as part of our industrial and civil service offering.
