Looking for expert CBR tests, plate bearing tests, or geotechnical testing services in Cambridge? From the Science Park to Trumpington, our local soil and ground investigation team delivers accurate data for construction and civil engineering projects, ensuring strong, reliable roads and foundations.
The Science of Soil & Ground Investigation in Cambridge
In Cambridge, it’s not just the centuries-old university that’s got history; the ground that our city is built on is a complex mix of Gault Clay, River Terrace Deposits, and deep-chalk layers that can make pavement construction and foundation design a right old headache. And if you take a one-size-fits-all approach, say, trying to treat the soil in Chesterton the same way as Newnham, you can end up with costly mistakes on your hands. So what’s the solution? Thorough site investigation and professional geotechnical testing, that’s what, and only that, can guarantee you designs that are cost-effective and meet the relevant standards.
At CBR Testing STS, our accredited engineers can offer a full range of ground investigation and material testing services in Cambridge, from CBR and plate bearing tests to advanced site testing and analysis. We bring a healthy dose of scientific rigour and professional experience to every project, using the best state-of-the-art equipment to give you accurate and reliable ground data.
What is a CBR Test & Why Does the California Bearing Ratio Matter?
You don’t need a degree to appreciate the value of a CBR test, but your design certainly does! The California Bearing Ratio (CBR) test is the industry standard for measuring the bearing capacity and stiffness of soil or subbase materials used in construction and road and pavement design, and it’s a crucial test for Cambridge’s often tricky ground conditions.
We do the test by using a cylindrical plunger to penetrate a soil sample or in-situ formation, measuring the load required to achieve standard penetration. This test simulates the pressure required to build a solid subgrade and ensures your design and construction meet all the civil engineering requirements.
- High CBR values: Indicate good, strong material and save on imported aggregate and subbase.
- Low CBR values: Warn of weak ground; design engineers need to reinforce with thicker material layers or ground stabilisation.
CBR testing is critical for pavement construction, road projects, car parks, cycleways, and foundation design across Cambridge.

CBR, Plate Bearing & Site Testing Services in Cambridge
In-Situ CBR Test
This is our go-to method for rapid assessment of formation level and subgrade strength. We do the test on-site using specialist equipment to give you instant CBR values direct from your soil or subbase, and that means you can do a proof test on your road or pavement before laying expensive materials.
Laboratory CBR Test
If you need more detailed ground investigation, we can transport a soil sample to our lab for comprehensive California Bearing Ratio testing. That’s ideal for checking how the material behaves when soaked or compacted, meeting road construction and adoption requirements.
Plate Bearing Test
This is a great companion to the CBR test, using a rigid metal plate to apply incremental load and measure the deformation or modulus of subgrade reaction. This is crucial for assessing the bearing capacity of soils intended to support heavy cranes, piling mats, or mobile plant equipment that’s essential in paving, piling, and foundation design.
Frequently Asked Questions
Can you test cycle paths, footways, and roads?
Of course, we do CBR and plate bearing tests for all types of infrastructure, from lightweight pavement to heavy-duty road construction.
How soon can I get the report?
In-situ tests give you provisional CBR values on the day; full site investigation and lab results are typically turned around within days, depending on test procedures like soaking.
Do you handle restricted city center sites?
Yes, we can; our portable state-of-the-art equipment means we can do material testing even in the narrowest and most historic streets in Cambridge.
Need both the CBR test and the plate bearing test?
Well, that depends on your project, but our comprehensive geotechnical testing services ensure every requirement is covered, whether it’s highway adoption, drainage, or foundation checks.
Can you analyse for soil contamination?
CBR testing looks at the strength of the soil, not what contaminants are present, but as part of our groundwork, we’re able to grab some soil samples & send them off for contamination analysis, all alongside your CBR and plate bearing tests if that’s what you need.
