Your local specialists for CBR testing in Liverpool
Before you start any construction project in Liverpool or the Northwest, you need accurate data about your site’s ground conditions. Our CBR Testing Liverpool service delivers fast, accredited results to determine soil strength, bearing capacity, and ultimate bearing capacity, so your designs meet every safety and compliance standard.
We do in situ tests and plate loading tests for road construction, foundation design, working platforms, and other civil engineering projects. Each test is carried out by experienced engineers using calibrated equipment to give you results within a working day.
What is a CBR Test?
The California Bearing Ratio (CBR) test is key to assessing the strength of soil and subbase materials used in construction. Developed by the California State Highway Department, the method compares the pressure required for a cylindrical plunger to penetrate compacted soil against the resistance of a standard crushed rock material.
This gives you CBR values that help you determine how well the ground will withstand applied pressure and wheel loads. The higher the CBR value, the stronger and more suitable the material is for pavement design, crane outriggers, and piling rig platforms.
Why Is It Important?
Liverpool’s ground conditions are varied, from sandstone bedrock to soft reclaimed soils near the docks. Without professional testing, you can’t predict how the site will behave under load. Our Liverpool services give you reliable results and insight into how your site will perform under real-world pressures.
With us, you can:
- Assess the bearing capacity and soil strength of natural or imported materials.
- Optimise pavement design and foundation depth with accurate data
- Minimise risk of settlement, failure, or costly rework
- Meet British Standards and Environment Agency requirements
- Support safe, durable construction projects in Merseyside
Our CBR and plate bearing tests are required at every stage of design and build, from initial investigation to final sign off.
We offer a full range of testing services across Liverpool and surrounding areas, available at short notice to fit your project schedule.
In Situ CBR Test
Our in situ test is carried out on your site using a tracked excavator or four-wheel drive vehicle to apply the test load. A cylindrical plunger is pressed into the surface under applied pressure, and the load required for equal penetration is recorded.
These in situ tests measure soil strength and bearing capacity in real field conditions. The results are used to calculate CBR values, so engineers can see how the ground will behave under expected traffic or construction loads.
Laboratory Testing
In the laboratory, soil samples are compacted and tested under controlled site conditions to simulate performance at depth. Factors such as moisture content, particle size, and load increments are analysed to give precise CBR values.
This standard test ensures the material used on-site meets the structural requirements for pavement design, foundations, and working platforms. Our laboratory team follows British and ISO-accredited procedures to give you reliable results you can trust.
Plate Load Test
The plate bearing test, also known as the plate loading test, determines the subgrade reaction, bearing capacity, and modulus of the ground. A circular steel plate of a specific plate diameter is placed on the surface and loaded incrementally using a hydraulic jack or loading plate. The applied pressure, vertical deformation, and load application are monitored. The test plate readings are used to calculate how well the ground can support a given load, essential for piling rig mats, crane outriggers, and working platforms.
This plate load method is a proven way to assess foundation design suitability and ensure your site can withstand the forces applied during construction.
