Fast, reliable, and efficient ground investigation services across Merseyside and the wider Northwest. Get the accurate data you need to design roads, foundations, pavements, and subbase materials with confidence.
Building in Merseyside? From the Liverpool waterfront to the Wirral coastline.
Merseyside is one of the UK’s busiest construction regions, with projects ranging from logistics hubs in Knowsley to residential developments in Sefton. Every single project starts with a pretty simple question: Do you have the CBR values and bearing capacity data you need to make informed civil engineering decisions? If you’re not sure about the ground beneath your feet, you could be in for a world of trouble.
Poor ground conditions can catch you out on even the best-planned project. You might be looking at settlement issues, cracking, delays, or unexpected costs. Our CBR testing Merseyside service takes the uncertainty out of the picture by giving you the accurate, site-specific information you need to make informed decisions. We give you the CBR data you need, delivered quickly, so your team can get on with calculating pavement design thicknesses, assessing subgrade reaction, and making sure the ground will take the strain.
Your On-Site Geotechnical Toolkit for Merseyside
We provide a focused suite of civil engineering tests designed for efficiency and clarity. Everything is carried out on your site, across all Merseyside locations, and performed in line with recognised standards.
In-Situ CBR (California Bearing Ratio) Test
The in situ CBR test is absolutely crucial for getting pavement design and road construction right. We measure how much a soil can withstand by comparing it to a standard crushed rock material, a bit like how much pressure you can put on a sponge. The test is done on your chosen test location, to BS 1377-9:1990, so you get the kind of data you need to understand real-world conditions, like moisture content and how well the soil has been compacted.
This test is a must-have for checking the quality of subbase materials and getting a handle on how much load the surface can take. It also gives your engineer everything they need to work out how thick the pavement needs to be, how it will perform in the long-term and whether they need to overdesign it.
Plate Bearing Tests (Plate Load Testing)
Plate bearing tests are vital for confirming the ground’s bearing capacity and settlement behaviour under load. They are frequently required for piling rig platforms, crane pads, temporary works, and foundations where concentrated loads are a factor.
We use various plate sizes, dial gauges, and controlled load application equipment to measure subgrade reaction, equal penetration, and pressure required for stability. The process is reliable and practical and provides engineers with definitive results to support safe, compliant construction.
Dynamic Cone Penetrometer (DCP) Analysis
The dynamic cone penetrometer is a super-fast way of getting an idea of how the ground is behaving. It helps you find weak layers, assess how well compacted the soil is, and get a handle on soil consistency over large sites. It’s perfect for when you need a quick fix for early design stages, value engineering, or checking imported materials.

Frequently Asked Questions (FAQs)
What exactly is a CBR value?
The California Bearing Ratio (CBR) indicates soil strength by comparing penetration resistance to a standard crushed rock material. Higher CBR values often lead to thinner pavement designs and more cost-efficient construction. It is essential for civil engineering purposes and forms the basis for pavement design calculations.
Is CBR testing necessary for smaller projects like driveways or extensions?
Yes. Any surface that must withstand vehicle loading should be assessed. A CBR test prevents issues such as rutting, sinking, and cracking. It is far more economical to conduct the test than to correct a failure after installation.
How long will the on-site process take?
Most of the tests get wrapped up in a few hours, depending on how many locations you’re testing and what kind of access there is on the day. We’re pretty efficient, and we can usually get it done and dusted before the end of the working day.
Do you cover all Merseyside areas?
Yep, we’re all over Liverpool, Wirral, Sefton, St. Helens, Knowsley & the rest of the North-west. Even if your site is quite remote, we should be able to come and do the tests.
What happens if the CBR value is low?
A low result doesn’t have to be a problem; it’s more just a starting point. Once we know how much pressure the soil can take, your engineer can come up with a plan to make sure it can handle it, which might mean making the base thicker, choosing better materials, improving drainage, or stabilising the soil. Knowing the problem early on gives you the chance to sort it out without it ending up costing an arm & a leg.
Ready to Build on Solid Ground?
Getting to know the ground you’re working on is the key to a safe and stress-free construction job. Whether you’re building a road, crane platforms, foundations, piling platforms, or a civil engineering scheme, getting accurate CBR and plate load data is a no-brainer if you want to avoid delays and risks.
