Get the Construction Soil Test Results You Need for Your Building Project in the UK
You need to know that your building project is safe, durable, and cost-effective. Our construction soil test provides accurate results that will give you confidence in your construction project.
Our California Bearing Ratio (CBR) testing services are an integral part of the soil analysis and laboratory testing process. This gives you the information you need about bearing capacity, moisture content, compaction characteristics, and overall soil strength. This means you can design stable foundations and pavements that meet the exact requirements of roads, airport runways, car parks, and other major construction projects.
We help you establish exactly how much load your ground can handle, avoid costly delays, and ensure your project meets the highest engineering and geotechnical standards.
What Is the Construction Soil Test (CBR Test)?
Engineers have relied on the California Bearing Ratio for years as a dependable way to check soil strength during a construction soil test. This test helps determine the engineering properties and bearing capacity of subgrade soil samples, base course materials, and other pavement layers.
It’s a method of testing developed by the California Division of Highways, and it measures how much force is needed to push a penetration piston into compacted soil at a specific moisture content and density. It’s a key geotechnical testing method recognised by transportation authorities all over the world, including the Federal Highway Administration and British Standards (BS 1377).
Engineers use CBR values from this soil testing process to design and verify foundations, roadways, runways, and other structures. By calculating the ratio of the load required to penetrate a sample to the standard load, you can establish the soil’s ability to support your construction project safely and effectively.
Our Construction Soil Testing Services
We provide a full range of soil testing services for all types of soil and construction applications.
On-Site CBR Test (Field Test)
Get quick, accurate results from field tests using calibrated equipment such as load frames, dial gauges, and base plates. Field testing is ideal for evaluating environmental conditions and soil behaviour directly on site.
Laboratory CBR Test
Test soil samples under controlled conditions in the laboratory to determine the California Bearing Ratio, dry density, optimum moisture content, and particle size distribution. Laboratory analysis provides reliable results for both residential and commercial projects.
Plate Bearing and Penetration Tests
Examine load capacity, surcharge weight, and shear strength of cohesive materials and base courses. Our laboratory analysis follows recognised geotechnical standards, providing accurate soil data for foundation design.
Detailed Test Reports
Get clear, data-driven reports with graphs, moisture content readings, compaction test results, and engineering recommendations for subgrade improvement and pavement design.
Engineering Support
Our geotechnical engineers will give you guidance on test selection, soil evaluation, and data interpretation. We’ll help you understand every result so you can make informed decisions about your construction project.
Our Construction Soil Test Process
Consultation & Planning
We’ll sit down with you to go over your site conditions, soil type, and project goals so we can choose the most suitable construction soil testing method. This ensures accurate soil analysis and dependable CBR values for your design.
Sample Collection or On-Site Testing
Our technicians will attend site to collect soil samples or conduct on-site compaction tests using calibrated instruments. Each soil sample will be tested for moisture content, density, and shear strength to give you a complete picture of your ground conditions.
Compaction & Analysis
Samples are prepared to match field moisture conditions and compacted to achieve maximum dry density. We then perform soil tests to measure resistance, specific gravity, and load capacity, ensuring your foundation design is based on solid, reliable data.
Reporting & Expert Advice
All results from your construction soil test will be compiled into a comprehensive soil testing report. Our engineers will translate complex data into actionable insights that help you build with confidence.

Frequently Asked Questions
What’s the Big Deal About Construction Soil Tests, Exactly?
Construction soil tests, using the California Bearing Ratio method among others, measure how strong and dense the soil is. It’s essential for figuring out if your building, road, or pavement will remain safe over time — and the less stress on the foundation, the better.
How Do They Go About Testing the Soil?
The process is simple: a technician pushes a metal rod or piston into the soil to see how much resistance it gives. Both on-site and laboratory tests assess how much weight the soil can take, as well as its density and moisture content. Both methods produce reliable results.
How Long Does It Actually Take to Get the Results?
Field soil tests can give you a result within a day, while lab tests typically take a bit longer — around two or three days. Both methods are useful for anyone involved in construction planning and design.
Do I Need to Do an On-Site Test or a Lab Test?
On-site testing is ideal if you want to see how the soil performs in real-life conditions, while lab testing is best for detailed insights into density, compaction, and moisture levels. We’ll determine the best option for your site.
What’s Actually in My Construction Soil Test Report?
The report includes CBR values, density measurements, moisture readings, and other engineering properties. It’s also a good idea to record site conditions, depths, and environmental factors relevant to your specific project.
