Services
Borehole Drilling
We deliver complete borehole solutions across varied geological conditions using advanced drilling techniques. Our capabilities include reverse circulation, direct flush rotary and down-the-hole hammer methods for depths up to 900 meters. We handle projects from feasibility through CDM compliance to final commissioning for both private and public sector clients. Our engineers apply tailored approaches to challenging environments including urban centres and environmental protection zones.
Geothermal Boreholes
Our geothermal drilling services provide sustainable energy solutions that reduce carbon emissions by 66%. We install vertical ground source heat pump systems that minimize surface disruption while achieving higher efficiency than conventional heating methods. Our expertise extends to connecting heat pump arrays with district heating networks, particularly in repurposing abandoned mine water for thermal energy applications.
Borehole Maintenance
We maximise borehole efficiency through comprehensive maintenance programs that optimise water yield and reduce energy consumption. Our services include relining wells with industry-standard materials, CCTV inspections and pump efficiency testing. We provide both reactive support and planned preventative maintenance to ensure regulatory compliance and extend asset lifecycle while minimising operational disruption.
Test Pumping
Our test pumping services evaluate aquifer characteristics using advanced hydrogeological assessment techniques. We conduct step drawdown testing, constant rate testing and multi-borehole analyses to determine optimal extraction parameters. Our equipment range from 1-310 l/s supports temporary pumping requirements with comprehensive data logging and real-time telemetry for informed decision-making.
Adit Construction
We construct and maintain underground water infrastructure using confined space specialists trained to industry standards. Our adit engineering services combine traditional construction methods with modern surveying technology, including remotely operated sonar and camera systems. We address both maintenance requirements for existing networks and new construction projects requiring specialist underground solutions.
