Planning a project in Norfolk? If you’re planning construction work in Norfolk, from King’s Lynn in the west to the coast at Great Yarmouth in the east, you can rely on us to provide timely, fully accredited geotechnical, ground investigation, and CBR testing services to give your project a solid foundation.

Why a Comprehensive Investigation in Norfolk Matters

When it comes to construction in Norfolk, ground investigation and site investigation are a must. What looks like a flat landscape at first glance hides some pretty complex ground conditions; think of sandy coastlines and peat fens or heavy clays inland. Every building project, whether it’s a desk study, a soakaway, or a plate bearing test, starts with getting a proper understanding of what lies beneath the surface.

Doing it right means avoiding all sorts of costly mistakes; over-engineering a project can be expensive, but under-engineering it can be downright dangerous. At CBR Testing STS Ltd, we provide clear, reliable data that helps design foundations and find solutions for highways, brownfield sites, and new build projects.

What is CBR testing? Why It’s Crucial

A California Bearing Ratio (CBR) test is a crucial geotechnical service and a vital part of ground investigation and materials testing. We use a standard plunger during in-situ testing to measure soil strength and come up with CBR values and important geotechnical information for engineers. This simple penetration test is a key tool in road and pavement design across the construction industry.

  • High CBR Values: That’s good news; your soil is strong, so you can save on imported materials and build infrastructure with confidence.
  • Low CBR Values: That tells you your soil isn’t as strong as it needs to be, so you may need to add some extra support, like a geogrid, a capping layer, or some more robust construction techniques.

Our Investigation Services

In-Situ CBR Testing and Ground Investigation

Our on-site investigation rig lets us carry out in situ penetration tests (like DCP or cone penetrometer tests) quickly and efficiently. We use your plant as a reaction platform if we need to and assess the strength and load-bearing capacity of the soil or subgrade on-site, which is ideal for earthworks, pavements, and new infrastructure projects.

Laboratory CBR Testing, Plate Bearing & Soakaway Testing

For more thorough assessment or to meet council requirements, we collect samples for laboratory CBR tests that simulate wet weather (BRE365 for soakaways, for instance) or undertake plate bearing tests to establish foundation and subbase performance. Our laboratory investigation covers permeability, risk assessments, contamination, and compaction quality.

Plate Bearing Tests & Desk Study

We’re not just CBR experts; we also do plate bearing, desk study services, windowless sampling, borehole installation, and trial pits, all the things you need to support sustainable drainage systems and solid foundation design.

Frequently Asked Questions

Is a CBR test essential for private developments?

Yeah, almost always. A CBR value is crucial for car parks, access roads, or hardstandings; it guarantees that your design will work long-term.

What do you need to undertake an in-situ CBR test?

Access for a 4×4 to each test point. If the terrain is tricky, we may need to use an excavator as the reaction weight.

How many site investigations/tests are needed?

Site investigation specifications usually call for a test every 20-30 metres or on a grid for car parks or large plots, though if the conditions are tricky, we may recommend more testing to get the most accurate results.

Can you test recycled materials and subbase?

Yeah, we’re happy to assess both soil and imported aggregates and make sure they’re compacted and have the right bearing capacity for your project.

Do you perform soakaway testing in Norfolk?

Yes, we do BRE365 soakaway tests, so you can design sustainable drainage systems with confidence.
