Coring Services
Precision Sampling and Structural Investigation Using Specialist Coring Equipment
Coring is a precise and controlled method used to extract samples from materials such as concrete and asphalt, or to create openings for further investigation works. Chelmer provide a specialist coring service as part of their wider site investigation offering, supporting both geotechnical assessments and materials testing requirements.
This method is commonly used where accurate sampling is required without causing unnecessary disruption to surrounding structures. By utilising modern coring equipment and experienced operatives, Chelmer are able to carry out works efficiently while maintaining a high level of accuracy and control.
Applications of Coring
Coring serves multiple purposes across site investigations and construction projects. One of its primary uses is to obtain samples of concrete or asphalt for laboratory testing. These samples can then be analysed to determine material properties such as strength, composition and condition, providing valuable information for design verification or quality assessment.
In addition to sampling, coring is often used as an alternative to more disruptive methods when creating openings through hard materials. For example, it can be used to form access points through concrete slabs prior to undertaking boreholes or other intrusive investigation techniques. This approach allows works to be carried out in a controlled and efficient manner, reducing the need for heavy breaking equipment.
Specialist Equipment and Capability
Chelmer utilise compact, highly manoeuvrable diamond-tipped coring rigs capable of operating in a wide range of environments. This equipment can be powered electrically or via generator, allowing flexibility when working on sites with limited access to power or where internal works are required.
The coring rigs used are among the most powerful in their class, enabling efficient cutting through a variety of materials while maintaining clean and accurate results. Their compact design allows access to locations that may otherwise be difficult to reach, ensuring that coring works can be carried out even in restricted or confined spaces.
Combined with the experience of Chelmer’s trained operatives, this equipment allows coring to be undertaken safely and effectively across a broad range of project types.
Supporting Site Investigation Works
Coring is often used in conjunction with other site investigation methods, forming part of a coordinated approach to ground and structural assessment. For example, coring may be undertaken to allow boreholes to be drilled through existing slabs or hardstanding, ensuring that underlying ground conditions can be investigated without unnecessary delay.
Where samples are taken, they can be transferred directly to Chelmer’s in-house UKAS accredited laboratory for testing. This integration ensures a smooth transition from site work to analysis, reducing turnaround times and maintaining consistency across the investigation process.
Materials Testing and Analysis
Samples obtained through coring are commonly used for materials testing, supporting both quality control and investigative works. Testing may include compressive strength testing of concrete, analysis of asphalt composition or assessment of aggregate grading and material quality.
This information is essential in a variety of scenarios, including verifying construction standards, assessing the condition of existing structures or supporting refurbishment and redevelopment projects. By providing accurate and representative samples, coring plays a key role in ensuring that reliable data is available for decision-making.
Integrated and Efficient Service
Chelmer’s coring services are fully integrated within their broader site investigation and laboratory offering. This ensures that all aspects of the process, from sampling through to testing and reporting, are delivered as part of a coordinated service.
By combining specialist equipment, experienced operatives and in-house analytical capabilities, Chelmer are able to provide a reliable and efficient coring service that supports a wide range of project requirements. Whether used for sampling, access or investigation purposes, coring remains an essential technique in delivering accurate and effective site investigations.
