Spencer Quantum Ltd

Spencer Quantum Ltd provides specialist geotechnical, geo-environmental, site and land services from its headquarters in Llandysul, with work delivered across the UK and internationally. Its geotechnical division supports infrastructure, utilities, energy and construction projects with investigation, testing, contracting and consultancy services.

The company operates its own fleet of drilling rigs and undertakes a broad range of ground investigations, including deep borehole investigations, cable percussion, rotary percussion, rotary coring, dynamic sampling and windowless sampling. Its wider investigation capability includes trial pitting, trenching, underground-services investigation, diamond coring, in-situ testing, laboratory testing and detailed technical reporting.

Groundwater and environmental monitoring form an important part of the service. Spencer Quantum installs and monitors piezometers, inclinometers, extensometers, settlement plates and other instrumentation, alongside groundwater, surface-water, ground-gas and vapour monitoring. It also provides water-quality testing, permeability and soakaway testing, geophysical and topographic surveys, and hydrogeological and dewatering studies.

The team works for public- and private-sector clients, including local authorities, utilities, infrastructure, energy and construction organisations. In addition to technical investigation, Spencer Quantum delivers geotechnical contracting such as slope stabilisation, soil nailing, ground anchors, rock bolting, mini-piling, grouting and vacuum excavation. Its complementary land-based services include temporary roadways, groundworks, site clearance, vegetation management, landscaping, river restoration and biomass operations.
