Geotechnical Laboratory Testing Services: Setting Solid Foundations with Accurate Data
Discover reliable, UKAS-accredited geotechnical laboratory testing and construction materials testing, for the construction industry, environmental projects, and geotechnical research.
STS provides expert laboratory testing, analysis, and support, to ensure your materials and results meet the standards you need for safety, compliance, and performance.
Soil, rock, aggregates, and the other materials on your site each have their own properties, and those properties drive decisions on foundation design, structural safety, and quality control. Our geotechnical laboratory testing and construction materials testing services give you the data you need to manage risk, meet regulatory compliance, and make informed decisions, without the guesswork.
Geotechnical Laboratory Testing and Construction Materials Testing
STS offers a full suite of geotechnical laboratory testing and construction materials testing services, covering soil, aggregate, rock, and water analysis for construction and civil engineering projects across the UK.
Soil Classification and Physical Properties Testing
Particle Size Distribution and Sieve Analysis: Determines the distribution of soil particles and grain sizes, supporting soil classification and stability assessments.
Atterberg Limits and Plastic Limit/Liquid Limit Tests: Establish key soil properties such as plasticity and how the material performs under changing moisture content.
Density, Unit Weight and Moisture Content: We determine bulk density, dry density, and natural water content for geotechnical design.
Strength and Performance Testing
California Bearing Ratio (CBR): Assesses subgrade soil bearing capacity, essential for preventing structural failures in civil engineering projects.
Shear Strength and Compression Tests: Shear box, shear vane, unconfined compressive strength, and oedometer tests determine engineering properties and control risk.
Durability and Permeability: We evaluate soil and rock for frost susceptibility, compaction, and permeability using wet and dry testing methods.
Chemical and Environmental Testing
Sulphate, Chloride, and Heavy Metals Analysis: Detects aggressive agents that affect concrete, steel, and human health, supporting environmental compliance.
pH Value and Electrical Conductivity: Measures soil characteristics affecting corrosion, agricultural suitability, and construction work.
Contaminant Detection and Waste Testing: Identifies contaminants in soil, water, and waste, supporting regulatory certification and project safety.
Our laboratories also cover water and food-related sample analysis for clients with wider testing needs. Get in touch to discuss your specific requirements.

Frequently Asked Questions
What role does laboratory testing play in construction? Laboratory testing confirms that materials such as soil, rock, aggregates, water, and waste meet the properties, quality, and safety requirements a project needs. It supports quality assurance, compliance, and helps you avoid costly issues once construction is underway.
Which geotechnical laboratory testing service will I need? That depends on your site and project. Common requirements include soil classification, Atterberg limits, and CBR testing, though some projects call for more complex environmental or analytical testing. Tell us the basics of your site or product, and we’ll recommend the right tests.
Are your labs UKAS accredited? Yes. Our laboratories hold UKAS accreditation and work to ISO and BS standards, so the analysis, results, and certification you receive are recognised for compliance purposes.
What is geotechnical laboratory testing? Geotechnical laboratory testing covers soil and rock tests, including particle size distribution, Atterberg limits, and CBR, used to assess ground conditions for construction and civil engineering projects.
What is construction materials testing? Construction materials testing covers laboratory and on-site assessment of the materials used in a build, including soil, aggregates, concrete, and water, to confirm they meet the required standards for safety and performance.
