Professional Soils Laboratory Doncaster laboratory

Professional Soils LaboratoryDoncaster, South Yorkshire

Professional Soils Laboratory’s Doncaster facility has Laboratory-coded aggregate, rock, soil and mixture methods in current UKAS 4043 issue 024. Selected groups cover classification, compaction/CBR, consolidation/permeability and shear. Site-only field tests remain separate. The owner and schedule use DN4 0AR, while the current UKAS result prints DN4 0AG. Confirm the delivery postcode, material, exact method and report with the provider.

Key facts

Exact laboratory and postcode discrepancy
The owner and schedule identify 5–7 Hexthorpe Road, Hexthorpe, Doncaster, South Yorkshire DN4 0AR, United Kingdom. The live UKAS result gives the same street/operator but DN4 0AG. This discrepancy is preserved, and sample delivery postcode needs confirmation.
Current official scope
UKAS 4043’s ISO/IEC 17025:2017 schedule is issue 024 dated 7 November 2024. All seven complete pages were inspected on 1 October 2026. The exact printed Laboratory and Site codes control method allocation.
Laboratory and field work
Retained Laboratory groups cover aggregates, rock, soils and unbound/hydraulically bound mixtures. Site-only density, plate loading and in-situ CBR methods are not local laboratory capabilities. Phenna network affiliation does not expand this exact schedule.
Published enquiry routes
Use the owner’s +44 1302 768098 and awatkins@prosoils.co.uk, printed in the schedule and corroborated by owner metadata. The schedule separately gives +44 844 815 6641 and names Mr A Watkins as a published contact, without a present job-role claim.

Testing capabilities

Scheduled aggregate and rock laboratory tests

Laboratory-coded aggregates use sieving to BS EN 933-1:2012, Los Angeles fragmentation to BS EN 1097-2:2020 and water content to BS EN 1097-5:2008. Rock rows separately cover point-load strength to the ISRM 1985 suggested method, unconfined compressive strength and water content using the cited ISRM 1974–2006 collection. No numerical strength or specimen range is given.

Scheduled soil classification and density

Laboratory soil rows include water/chalk saturation, liquid and plastic limits, indices, shrinkage, particle sizing and density under the printed BS 1377-2:2022 methods. Separate geotechnical rows list BS EN ISO 17892-1:2014 water content, -2:2014 bulk density, -4:2016 sieving/pipette sizing and -12:2018 limits/indices. Gas-jar density and pipette sizing remain exact techniques, without absent amendments added.

Scheduled compaction and laboratory CBR

Laboratory-coded BS 1377-2:2022 rows include dry-density/moisture relationships with 2.5 kg and 4.5 kg rammers or a vibrating hammer, laboratory CBR and CBR soaking. Natural-water MCV is coded Laboratory and Site, while MCV/water-content relationship is Laboratory. In-situ CBR and plate-derived equivalent CBR are separate Site methods and are not allocated locally.

Scheduled consolidation and triaxial-cell permeability

Laboratory rows list one-dimensional consolidation to BS 1377-2:2022 and an incremental-loading oedometer test to BS EN ISO 17892-5:2017. Triaxial-cell permeability has separate BS 1377-2:2022 and BS EN ISO 17892-11:2019 rows. Exact specimen, material, saturation and method conditions require agreement, without an unrestricted permeability or capacity range inferred.

Scheduled laboratory triaxial, shearbox and ring-shear tests

Laboratory methods include undrained/effective triaxial strength, small/large shearbox and residual ring shear under the exact BS 1377 rows, with separate multistage and in-house conditions. Geotechnical rows list BS EN ISO 17892-8:2018 unconsolidated-undrained testing, -9:2018 consolidated tests on water-saturated soil and -10:2018 small/large/ring direct-shear tests. These conditions are not interchangeable.

Scheduled unbound and hydraulically bound mixture testing

For unbound and hydraulically bound mixtures, MCV to BS EN 13286-46:2003 is coded Laboratory and Site. CBR, immediate bearing index and linear swelling to BS EN 13286-47:2021 are Laboratory-coded. Material-specific mixture rows remain separate from the soil and field CBR methods.

Standards and accreditation

UKAS 4043 exact Laboratory allocation
Current issue 024 dated 7 November 2024 links Doncaster’s Laboratory code to its printed aggregate, rock, soil and mixture rows. Site-only methods are kept separate. Exact BS 1377, BS EN ISO 17892, ISRM and BS EN 13286 editions control retained claims, without later amendments inferred.
Owner and network scope boundaries
Owner references to all standards, latest equipment, accredited apparatus and wider Phenna expertise do not add methods or transfer other companies’ accreditation. Qualitative owner warehouse information is separate from scheduled equipment limits. Field service advertising does not make Site-only methods laboratory tests.

What to confirm with the facility

  • The owner and schedule postcode DN4 0AR conflicts with current UKAS result DN4 0AG for the same Hexthorpe Road site. Confirm the exact sample-delivery address. Owner phone and schedule phone differ, and a published A Watkins contact does not establish a present job role.
  • Retain the exact Laboratory material/method/edition conditions. Site-only sand replacement, core cutter, plate loading, in-situ CBR and plate-derived equivalent-CBR load range are excluded from local capability. Group/network affiliation, staffing and general equipment advertising do not expand scope.
  • Provide material, sample condition and quantity, preparation, requested method and edition, laboratory or field location, report requirements and programme so the provider can confirm suitability and cost.

Sources and review

Reviewed by Arc on 1 October 2026 in Europe/London using four fresh official sources and all seven complete pages of current UKAS 4043 issue 024. Six concise groups use Laboratory-coded rows only. The owner/schedule DN4 0AR address is retained with explicit disclosure of current-register DN4 0AG and delivery confirmation. Exact BS 1377 and BS EN ISO 17892 editions and Laboratory/Site distinctions are preserved, without absent amendments or the field equivalent-CBR load range transferred. Owner phone and schedule phone, directly printed email and named-contact wording remain distinct. Phenna group/network and staff/equipment advertising do not extend scope. Original bodies, headers, retrieval metadata, titles, canonicals, owner Organization contact metadata, PDF extraction and all seven renders are retained. Issue and PDF records from 7 November 2024 are separate from this review. UKAS template dates, company history, image queries and copyright are not page updates. Both prior discovery originals remain unchanged. The prior owner HTML raw body differs from the fresh original, while full visible text, publisher metadata and decoded contact links corroborate retained claims. The prior PDF is byte-identical to the fresh schedule. Imported postcode coordinates are cleared.

    United Kingdom Accreditation Service · Reviewed

    Current UKAS 4043 issue 024 dated 7 November 2024 identifies 5/7 Hexthorpe Road, Hexthorpe, Doncaster DN4 0AR as Laboratory for aggregates, rock, soils and unbound/hydraulically bound mixtures. All seven complete pages were visually inspected. Six retained groups use Laboratory-coded rows only. Site density, plate loading, in-situ CBR and the 1–500 kN equivalent-CBR field range are not local laboratory capabilities. Printed BS 1377 and BS EN ISO 17892 editions remain distinct without absent amendments inferred. PDF creation/modification on 7 November 2024 at 11:01:05 UTC is separate from the issue record and current review. Schedule awatkins@prosoils.co.uk / +44 844 815 6641 remains distinct from owner phone.

  2. UKAS Professional Soils Laboratory current result

    United Kingdom Accreditation Service · Reviewed

    The current exact UKAS result links Professional Soils Laboratory to schedule 4043 and the same Hexthorpe Road site, but prints DN4 0AG rather than schedule/owner DN4 0AR. The discrepancy is disclosed, without inventing a relocation. Generic directory-template publication in 2020 and modification in 2022 do not date the result.
