Structural Soils Castleford Laboratory

Structural SoilsCastleford, West Yorkshire

UKAS 1774 issue 048 identifies The Potteries, Pottery Street, Castleford, and assigns its laboratory methods to pages 9–12. These cover aggregates, soils and unbound/hydraulically bound mixtures. The broader Bristol rock/triaxial/thermal methods and off-site field tests are separately allocated.

Key facts

Separate laboratory allocation
The Potteries, Pottery Street, Castleford, West Yorkshire, WF10 1NJ. UKAS 1774 issue 048 dated 22 June 2026 separates this laboratory from the organisation header, the other two laboratories and off-site field activities.

Testing capabilities

Aggregate grading, durability and physical tests

The Castleford rows list grading, flakiness, methylene-blue fines, recycled-aggregate constituents, Micro-Deval wear, Los Angeles fragmentation, loose bulk density, moisture, particle density/water absorption and magnesium-sulphate testing.

Soils and bound/unbound mixture methods

The local soil scope includes classification, compaction and density, CBR/swelling/MCV, unconsolidated-undrained triaxial, consolidation/oedometer and small-shearbox methods. Mixture reference density uses vibrating-hammer or Proctor methods, with CBR/bearing-index/swelling testing.

Equipment and published limits

Standards and accreditation

UKAS 1774 — specific laboratory allocation
Issue 048 dated 22 June 2026 states ISO/IEC 17025:2017 and lists method-specific BS 1377, BS EN ISO 17892, ISRM and other references under separate laboratory sections. Confirm the particular product/method and listed edition; accreditation is not a combined group-wide scope.

What to confirm with the facility

  • The Castleford pages do not allocate Bristol’s wider rock, consolidated triaxial, thermal or ring-shear suite to this site. Site-code field methods are separate from Castleford laboratory methods.
  • Confirm the exact product/method allocation, specimen preparation, usable capacity, current accreditation scope, availability, reporting and quotation.

    Issue 048 dated 22 June 2026 identifies separate Bristol, Castleford, Hemel Hempstead and Site allocations. Only the Structural Soils Castleford Laboratory methods above are adopted; shared organisation headers and other-location methods never create local scope.
