Expert on-site CBR testing services and ground investigation across Bath and North East Somerset. Get the precise data you need to ensure your project stands the test of time.
Don’t Let Ground Conditions Undermine Your Bath Project
Bath’s unique mix of Georgian streets, riverside developments, and hillside construction sites makes every build a challenge in its own right. Whether you’re close to the River Avon or working on sloping terrain, the ground conditions beneath your site hold the key to safe, compliant engineering.
Skipping proper site investigations means building blind. Without knowing the load-bearing capacity of the subgrade soil, you risk pavement failures, settlement, and costly remedial works. Our CBR Testing Bath services provide the reliable California Bearing Ratio (CBR) values your design team needs to make informed decisions for pavement and foundation design.
With accurate testing, you’re not guessing; you’re building on certainty.
A Full Suite of Testing Services for Bath
Bath is the perfect example of a city with geology that varies from one location to the next. Each site demands a different approach, and that’s why we offer a flexible range of testing services. We’ll help you gather the critical information you need for safe, efficient construction.
In-Situ CBR Testing
The California Bearing Ratio test, originally developed by the California State Highway Department, remains the industry benchmark for assessing the strength of compacted soil, subgrade, and subbase materials.
We perform each CBR test on-site in accordance with BS 1377-9:1990, using a cylindrical plunger and standard load to measure the pressure required to achieve equal penetration into the ground.
Our process provides:
- True CBR values based on natural site conditions
- Data required for accurate pavement design
- Insight into foundation design and civil engineering purposes
- Confidence that your proposed construction centreline sits on reliable soil
Each CBR test performed offers immediate clarity on the strength of your soil sample, including moisture effects and penetration resistance.
Plate Bearing Tests & Plate Load Tests
If your project involves cranes, piling mats, or temporary platforms or structures under imposed load, you’ll need to do a plate bearing test, also known as a plate load test. We use a steel plate, selected to the right size and standard area, to apply a controlled load at a steady rate. This lets us measure:
- Settlement behaviour under load
- The bearing capacity of the ground
- Suitability for heavy plant and working surfaces
This test is especially valuable for ensuring that your civil engineering works remain safe, stable, and compliant.
Dynamic Cone Penetrometer (DCP)
If you need to get a quick picture of ground strength at depth, then our DCP testing is the way to go. We can identify weak zones, variable compaction, layer inconsistencies, and the performance of high-quality sub-base material. DCP testing is ideal for checking compaction across a typical site or confirming the consistency of imported fill.

Common Questions About CBR Testing in Bath
What is the California Bearing Ratio (CBR)?
The California Bearing Ratio CBR value compares your soil’s strength against a standard crushed rock material. A higher value means stronger ground and thinner pavement layers. The test was originally developed by the California Division and is now the standard in UK civil engineering.
Do I really need a CBR test for a small car park?
Yes. Any surface that’s going to take vehicles, whether it’s concrete, tarmac, or block paving, needs a proper pavement design. A CBR test ensures the construction is safe and compliant
How disruptive is the testing?
Most testing is low-impact. Because our rigs are often single-operator, portable, and efficient, we can test at surface level or shallow depth without interrupting your wider project.
Do you cover areas beyond Bath?
Absolutely. We work across Bath and surrounding towns, including Keynsham, Midsomer Norton, Radstock, and local villages.
My site has difficult access. Can you still test?
Yes. Many of our field tests can be performed in tight or restricted zones. Just let us know about any limitations so our team can prepare the right equipment.
