Services

Below is a bit more detail about all the services we offer. Please get in touch by email or telephone to discuss any your needs or queries.

Phase 1 Desk Study

Core Geotechnics undertakes initial site assessments and appraisals to identify potential geotechnical and geo-environmental risks and allow economic design for Phase 2 intrusive investigation. Ground risks such as contamination, ground gas as well as geotechnical issues such as desiccation, dissolution features, mining etc are assessed with reference to various site specific geological and geo-environmental data sources. Where necessary we liaise with the Environmental Agency, Local Authority and Coal Authority to ensure the study addresses correctly the risks and minimises any future potential programme delays to our clients. The Phase 1 appraisals are carried out by a Chartered Geologist who will use professional experience and due diligence to provide a realistic assessment of identified risks and minimise the potential for unforeseen ground problems which could generate time delays and added costs during the construction phase.

Ground Investigations

Core Geotechnics solid background in the UK ground investigation industry ensures the most appropriate methods and equipment are employed on any given site for the anticipated geology. Our site work services include:

Hand and machine excavated trial pits
Hand held window sampling
In-situ testing including CBR, plate bearing tests, dynamic probing and cone penetration testing, geophysical techniques and pressuremeter testing
Drilling of boreholes utilising dynamic sampling, cable percussion and rotary techniques
Installation of monitoring instrumentation – standpipes, piezometers, inclinometers, extensometers and survey datums
Soakaway and soil permeability testing

In recognition of the need to ensure good quality ground data, all site works are supervised by a Chartered Geologist who would have designed the investigation and prepared the report. Post site work services include:

Monitoring for groundwater, gas, lateral and vertical ground movement
Geotechnical laboratory testing to UKAS standards
Contamination laboratory testing with MCerts accreditation
