Holequest

Holequest is an experienced geotechnical contractor based in Galashiels in the Scottish Borders, delivering ground investigation, well drilling and specialist engineering services across Scotland, northern England and beyond. Established in 1974, the company works on projects ranging from smaller private supplies to complex marine and infrastructure investigations.

Its well services cover the route from groundwater source to end use. Holequest drills and constructs boreholes, supplies and installs pumps and control systems, and designs water-treatment equipment and distribution pipelines. The team also undertakes yield and drawdown testing, water-quality testing, groundwater investigations, private water-supply assessments and advice on permits, regulations and licensing. Geothermal heating systems and renewable-powered borehole pumps are also available.

Alongside water projects, the company provides site and ground investigation, contaminated-site investigation, environmental and geotechnical monitoring, soakaway and permeability testing, sampling, rock coring and reporting. Its wider engineering work includes marine investigation, structural repairs, foundation solutions and permanent or temporary ground anchors. Maintenance, repair and camera surveys can help diagnose problems in existing boreholes and support rehabilitation planning.

Holequest supports individual homeowners, off-grid properties, farms, agricultural and irrigation projects, commercial and industrial clients, housing schemes, local authorities and major infrastructure teams. Its equipment includes tracked percussion and rotary drilling rigs, a borehole camera capable of surveying to substantial depth, and specialist access equipment for near-quayside work. With dedicated offices, training, storage and maintenance facilities, the company offers a practical, technically focused service for projects that need investigation, design, supply and installation in one coordinated team.
