Ground truth is our business in Cardiff, and we deliver it fast and reliably. We’re here to help you build safely, compliantly and cost-effectively across South Wales by delivering precise CBR values, plate bearing results and dependable ground investigation data.
Building in Cardiff? Do Not Let the Ground Be a Guessing Game
Cardiff is being reshaped by development, from big residential schemes in Pontprennau and Lisvane, to infrastructure and road works right across the docklands and city centre. Every project relies on one critical variable: the strength and stability of the ground underneath.
Not doing your site investigation and site testing properly can leave a project at risk of settlement, pavement collapse, foundation instability and costly delays. Too many people in the construction industry are having to learn that lesson the hard way. Proceeding without a solid understanding of ground conditions, soil strength and load-bearing capacity is a game that’s best avoided.
Our CBR testing services in Cardiff give you the reliable data you need. By figuring out the California Bearing Ratio, we provide engineers, contractors and developers with the lowdown they need to design pavements safely, get foundations right, and make confident decisions.
If you are looking for CBR testing in Cardiff that you can trust, you need an experienced team that knows the local patch.
Comprehensive Geotechnical Services for Cardiff Sites
We deliver a comprehensive range of geotechnical services and site testing services, carried out by experienced geotechnical engineers using calibrated, state-of-the-art equipment. Our services are designed to meet real-world project requirements, not overcomplicate them.
In-Situ CBR Testing (California Bearing Ratio Test)
CBR testing is the benchmark method for assessing subgrade soil strength. Our in situ testing follows BS 1377-9, using the standard plunger method with equal penetration measurements to determine resistance under load.
- Determines precise CBR values
- Assesses bearing capacity and subgrade reaction
- Uses a 50mm plunger suitable for fine-grained soils
- Provides reliable data for pavement design and road construction
- Minimises disruption with fast, on-site testing
Results are expressed as a percentage relative to the standard load defined by the Transport Research Laboratory, originally developed by the California State Highway Department.
Plate Bearing Tests and Plate Load Tests
Plate bearing tests (also known as plate load tests) are a must for working out ground bearing capacity and long-term performance under heavy load.
These tests are a must-have for:
- Foundation design
- Crane pads and piling mats
- Temporary works
- Hardstandings and infrastructure
By applying a load to the surface and measuring settlement, we can tell you whether the ground is stable, how loads distribute, and how it will perform over the long-term.
Dynamic Cone Penetrometer (DCP) Testing
DPCT can give you a pretty good idea of soil strength at depth. This works by using a hardened metal cone to profile resistance changes through the soil column.
While DCP testing will give you some helpful information rather than definitive CBR results, it’s still a great tool for identifying weak zones, evaluating subgrade soil, and helping steer ground investigation strategies
Laboratory Testing and Soil Analysis
Where required, we also offer laboratory testing to support complex or large-scale projects.
Laboratory services include:
- Soil classification
- Dry density determination
- Maximum particle size assessment
- Controlled moisture testing
- Soaked and unsoaked CBR testing
Laboratory tests allow controlled analysis of soil samples, although results may differ from field conditions. We advise on the correct balance between laboratory and in-situ testing to ensure accurate results.
Why Cardiff Construction Professionals Choose Us
We work with contractors, consultants, and environmental consultancy teams across South Wales, delivering testing services that align with site realities and programme pressures.
Local Ground Expertise
Cardiff has its own unique set of challenges, like

Timely service is critical. Certified test results can be delivered within 24 hours, helping projects remain on schedule and compliant.
Clear, Actionable Reporting
Our reports provide:
- Accurate measurements
- Clear interpretations
- Practical recommendations
- Data tailored for structural engineers
No unnecessary jargon. Just valuable insights that support design decisions.
An Experienced, Professional Team
Our experienced team delivers exceptional service, working efficiently on live sites and communicating clearly with all stakeholders.
How CBR and Plate Bearing Testing Add Value to Your Project
- Helps you choose the right materials the first time, and reduces waste
- Gives you the confidence that your construction materials meet spec
- Supports compliance with British Standards
- Prevents costly settlement and foundation failure
- Keeps your project durable and performing well over the long-term
Finding out about weak ground early on lets you implement soil improvement techniques before problems get out of hand.
Frequently Asked Questions About CBR Testing in Cardiff
What does a CBR test measure?
The California Bearing Ratio test measures penetration resistance under load, providing a percentage value that reflects soil strength compared to crushed rock.
Is CBR testing necessary for small projects?
Yes. Any surface designed to carry a load requires accurate CBR values to avoid premature failure.
Can CBR testing be carried out on-site?
Yes. In situ CBR testing quickly determines bearing capacity without removing material, making it ideal for live construction sites.
What if the ground conditions are poor?
Low values are not a failure. They inform design adjustments, such as thicker sub-bases or soil reinforcement, saving money long-term.
