Get Reliable CBR Testing for Your UK Construction Project

Ensure your building project is safe, durable, and cost-effective with accurate California Bearing Ratio (CBR) testing. Our soil testing services provide reliable assessments of soil strength, offering critical insights into bearing capacity, penetration resistance, and compaction characteristics. With these results, you can confidently design roads, airport runways, car parks, and flexible pavements. We help you determine how much load your site soils can handle, avoid costly delays, and meet the highest geotechnical standards.

What is CBR Testing and Why Soil Testing Matters

CBR testing is a trusted method for assessing the strength and bearing capacity of subgrade samples, base course materials, and other pavement layers. The test measures the force needed to penetrate compacted soil with a standard piston under controlled depth and moisture conditions.

Engineers rely on soil testing to design, evaluate, and refine foundations, roadways, parking lots, and other infrastructure. By comparing applied loads to measured resistance, CBR testing ensures the soil’s strength and saturation are suitable for construction requirements. If you are searching for soil testing near me, our team can provide professional on-site support across the UK.

Our Soil Testing Services in the UK

We offer a full range of soil testing services to suit any soil type or construction project, providing accurate CBR assessments for a variety of applications.

On-Site CBR Testing (Field Test)

Our on-site CBR testing delivers fast, reliable results using standardised procedures and calibrated equipment, including load frames, penetration pistons, dial gauges, base plates, and surcharge weights. This is ideal for assessing in-situ soil conditions and real-world performance.

Laboratory Testing

CBR testing is also conducted in controlled laboratory conditions using compacted soil samples. This allows precise measurement of ground strength, dry density, optimum moisture content, and maximum particle size.

Plate Bearing and Penetration Tests

We also perform plate bearing and penetration tests to evaluate load response, surcharge load, and penetration resistance for cohesive soils and base course materials. All procedures follow recognised industry standards.

Detailed Reports and Expert Guidance

Our test reports include clear graphs, charts, calculations, and field correlations. Each report offers practical recommendations for subgrade improvement, flexible pavements, and foundation design.

Our experienced engineers provide guidance on selecting the right soil testing services, interpreting results, and applying the findings to ensure durable roads, pavements, and structures.

How Our Soil Testing Process Works

Consultation & Planning

We assess your site conditions, project scope, and environmental factors to choose the most suitable CBR testing approach — on-site or lab — for accurate results.

Sample Collection or On-Site Testing

Technicians collect representative soil samples or conduct penetration tests using standardised methods and calibrated equipment.

Compaction & Analysis

Samples are prepared to the correct dry density and moisture content, compacted to reflect field conditions, and measured for load resistance.

Reporting & Expert Advice

Results are converted into actionable reports, including load readings, penetration resistance, and moisture data. All documentation supports pavement and foundation planning.

Frequently Asked Questions

What is soil testing and why is it important?

Soil testing evaluates the strength, compaction, and bearing capacity of subgrade soils and base materials. It’s essential for calculating pavement and foundation thickness to ensure long-term safety and performance.

How is CBR testing performed?

CBR testing applies controlled force to compacted soil, either in the lab or on-site. Load resistance and penetration data are collected and processed to deliver reliable results.

Do I need on-site or laboratory soil testing services?

On-site testing is best for understanding soil under real conditions, while laboratory testing provides detailed density, moisture, and compaction analysis. We help you determine the right approach.

What’s included in my test report?

Reports summarize CBR results, testing methods, site conditions, and actionable recommendations. All documentation is suitable for design, planning, and regulatory compliance.
