AWK Ground Testing

AWK Ground Testing is a UKAS-accredited geotechnical and construction materials testing company headquartered at 8 Atlas Court, Atlas Road, Coalville, Leicestershire, LE67 3FL. With more than 20 years of industry experience, the company has established itself as a trusted specialist in site investigation, soil testing, and in-situ field assessments for construction and civil engineering projects throughout the United Kingdom. Serving contractors, structural engineers, geotechnical consultants, and developers, AWK Ground Testing provides the technical rigour and practical insight needed to underpin safe, compliant, and cost-effective construction.

AWK Ground Testing holds UKAS accreditation under certificate number 20561, confirming that its laboratory and field testing activities meet the internationally recognised requirements of ISO/IEC 17025. This accreditation, issued by the United Kingdom Accreditation Service — the UK's national accreditation body — gives clients confidence that results are technically valid, traceable, and defensible for regulatory and contractual purposes. The company's scope of accreditation covers the specific geotechnical activities listed on its official UKAS schedule, and all testing is executed by a skilled team with deep specialist knowledge of soil mechanics and construction materials science.

In-situ field testing forms a core pillar of the company's service portfolio. Plate Bearing Testing (Plate Load Test) is performed to assess the load-bearing capacity and deformation characteristics of the ground, yielding essential design parameters for foundations, roadbeds, pavement structures, and other engineered works. Lightweight Deflectometer (LWD) testing offers a rapid and cost-effective alternative for evaluating stiffness and compaction quality of subgrades and granular layers, delivering immediate on-site results to support compaction verification and earthworks quality assurance. Ultimate Bearing Capacity testing determines the maximum sustainable load before ground failure, providing critical data for the design of piling mats, crane pads, and temporary works platforms. Hand Shear Vane Testing enables quick in-situ measurement of undrained shear strength in cohesive soils, helping engineers assess slope stability and suitability of ground conditions prior to or during construction operations.

AWK Ground Testing operates a comprehensive laboratory testing service covering the fundamental suite of soil characterisation and geotechnical analyses required for site investigations and ground assessments. Laboratory services include moisture content determination, Atterberg Limits testing (liquid limit and plastic limit) for derivation of the plasticity index, particle size distribution analysis by sieve and hydrometer methods, soil classification in accordance with recognised geotechnical standards, and soil strength assessment. These parameters are used by geotechnical engineers to classify soils, model ground behaviour, design earthworks and foundations, and verify specification compliance. The UKAS-accredited laboratory procedures ensure results are reproducible, traceable, and produced under robust quality management controls.

Asphalt testing is a further specialist capability offered by AWK Ground Testing. Services in this area include asphalt core sample analysis, PAK marker testing — used to identify the presence of coal tar binders in road-bound materials in the context of waste classification and disposal — asphalt temperature recording during laying operations to verify compliance with mix-design and specification requirements, and a range of other pavement-related assessments. These services support highway engineers, surfacing contractors, local authority clients, and infrastructure project teams in demonstrating regulatory compliance and in conducting condition assessments of existing road surfaces.

The company serves a broad client base drawn from across the UK construction and civil engineering sectors. Typical clients include main contractors, specialist geotechnical contractors, structural and civil engineering consultancies, highways and infrastructure teams, and developers working on residential, commercial, and industrial schemes. AWK Ground Testing's combination of accredited field and laboratory services makes it a single-source testing partner for ground investigation and construction materials requirements, reducing coordination overhead for project teams who would otherwise need to engage multiple providers.

Based in Leicestershire in the East Midlands, AWK Ground Testing deploys field teams across the United Kingdom and also accepts submitted samples for laboratory analysis. The company's positioning — combining UKAS accreditation, a 20-year track record, fast turnaround, nationwide reach, and a comprehensive service range — makes it especially well-suited to time-sensitive construction projects where delays in testing data can affect programme and budget. Geotechnical reports and test certificates produced under UKAS accreditation are also routinely relied upon in construction disputes and litigation, providing clients with defensible, independently validated evidence of ground conditions and materials compliance.
