Targeted ground testing to confirm bearing performance, support design and keep construction moving.
CBR and plate testing are usually required to confirm design assumptions, satisfy building inspectors, or sign off earthworks.
We deliver testing services with a clear understanding of how results are used in practice: to unlock construction stages, support technical approvals, and avoid unnecessary over-specification.
Rather than just issuing a report, we focus on targeted test locations and the rapid communication of reliable in-situ data.
Where results are marginal or variable, we provide the technical interpretation needed to help engineers and site teams understand exactly what the data means for the design and the construction programme.
For project specific advice
Testing scoped around construction activities, design needs and inspection requirements.
Results are interpreted in the context of pavement, foundation or earthworks performance.
Testing aligned with earthworks, remediation and design strategies.
Testing regimes developed to answer real engineering questions, not just generate data.
CBR (California Bearing Ratio) and plate bearing tests are essential in-situ methods used to assess the strength and load-bearing performance of soils, made ground, and constructed layers.
While they measure different properties, both are critical for verifying that the ground can safely support the intended loads, whether from a new road, a building foundation, or heavy construction plant.
A well-planned testing programme provides the engineering confidence needed to move a project forward. By validating the ground’s performance on-site, we help teams avoid the costs of over-engineering while ensuring full compliance with design and regulatory standards.
While the scope is always tailored to specific site objectives and ground conditions, our testing process typically includes:
CBR and plate testing is commonly undertaken during active site phases.
Early-stage testing to support or refine engineering assumptions, allowing for improved foundation and pavement designs based on real-world site data.
In-situ testing of treated ground, improved soils, and prepared formations to confirm they meet the required performance standards for development.
Targeted testing to support the design and execution of roads, yards, and hardstandings, preventing over-specification and ensuring long-term durability.
Technical verification of improved ground and remediated areas, providing the engineered evidence needed to prove the site is fit for purpose.
Provision of clear, decision-led reporting to support technical inspections, satisfy warranty providers, and secure final regulatory approval.
Understanding the design, construction stage, and testing objectives.
Definition of appropriate test types, locations, & quantities to meet technical & regulatory requirements.
Undertaking in-situ CBR and/or plate bearing tests using calibrated equipment and industry-standard methodologies.
Clear presentation and interpretation of results, including discussion of findings and their implications for the project.
We provide the expertise to simplify complex challenges for faster approvals of tough planning requirements.
Still have any questions about due CBR, plate testing or planning?
Testing is typically required during earthworks, formation preparation, or pavement construction.
It’s essential whenever designers need to confirm ground performance assumptions or when building inspectors require formal validation before signing off a construction stage.
Yes. We regularly support active construction and enabling works.
We coordinate closely with site teams to ensure testing is carried out safely and efficiently, minimising disruption to ongoing earthworks or machinery movements.
Yes. We provide technical interpretation. This helps designers and project managers understand if the results meet the required specifications or if design adjustments are necessary based on the in-situ data.
Yes. Testing is most effective when integrated with remediation and earthworks verification. By linking these services, we provide a continuous record of ground performance from the raw site through to the final formation.
Yes. Our outputs are regularly used to support technical approval and construction sign-off.
They provide the engineering evidence required to secure technical approvals from local authorities, warranty providers, and third-party inspectors.
