We get the ground truth on your construction projects fast, providing compliant reports in just 24 to 48 hours, so you can move forward with confidence.
Constructing in Guildford? First, Understand Your Ground.
Guildford is a hotbed of development in the South-East, with projects popping up left and right across all sorts of sectors, from residential to commercial to infrastructure. From the river to the Surrey Hills, ground conditions can change in a heartbeat, so it’s no surprise that local geology like chalk, clay, sand and made ground can give you some nasty surprises.
We’re talking about chalk, clay, sand and mixed ground, all of which can have a big impact on load, settlement and long-term performance and throw California Bearing Ratio values out the window. Seasonal moisture variation adds to the complexity, making it a real challenge to get reliable on-site testing.
Starting out without a solid site investigation and some decent CBR data is a recipe for disaster; expect delayed projects, cost blowouts and who-knows-what in terms of health and safety risks. Our CBR testing Guildford service is here to give you the clear, factual data you need to make informed decisions at every stage of development.
CBR Testing in Guildford: Accurate, Compliant, and Practical
CBR testing is a geotechnical procedure used to evaluate sub-grade ground strength for roads, pavements, and foundations. It is an integral part of pavement and highway design and is specified in BS 1377: Part 9:1990 – Soils for Civil Engineering Purposes.
The CBR value is calculated by comparing the pressure required to achieve equal penetration into the soil against a high-quality, standard crushed rock material. A higher CBR value indicates harder, more suitable ground.
CBR testing provides civil engineers with the data needed to:
- Determine layer thicknesses
- Specify suitable construction materials
- Identify weak ground before failure occurs
- Prevent premature road deterioration and hazardous settlement
Testing is typically undertaken on-site at regular 20–30m intervals along the proposed construction centreline, ensuring reliable coverage across the full development area.
Our Geotechnical and Site Investigation Services in Guildford
We’ve got a comprehensive range of site investigation and testing solutions, delivered across multiple locations in England and the wider UK.
In-Situ CBR Testing
Carried out on-site in accordance with BS 1377, in-situ CBR testing measures how soil performs under load at the surface. It gives you the data you need to design safe and cost-effective pavements, access roads and foundations.
Plate Bearing Tests and Plate Loading Tests
The plate bearing test is an in-situ field assessment used to determine the ultimate bearing capacity of soil and rock. It’s often used for temporary works like crane pads, piling platforms and heavy plant installations. Plate loading tests give you the essential settlement and load data where safety margins must be rock solid.
Site Investigation and Ground Investigation Services
A site investigation is used to figure out the properties of soil and rock and how they might behave when development starts. It might involve:
- boring into the ground and trial pits
- sampling and lab analysis
- chemical analysis of soil and water
- environmental site investigation and contamination checks
Phase 2 site investigations are needed where risks are identified during a Phase 1 desk study. The report covers ground conditions, contamination risks and recommendations to meet local authority and Environment Agency requirements.
Additional Investigation and Testing Support
Sometimes investigations also involve:
- cable percussion drilling
- in-situ testing in boreholes, including SPT and permeability testing
- materials testing and lab assessments
- risk assessment and geotechnical analysis
Supporting Construction Projects Across Surrey and Beyond
Our services support construction projects across Surrey, the South-East, and other locations, including London, the South, the East, and North Yorkshire. The cost of CBR testing remains consistent due to our established network and coverage across the UK.
