TD - Ensuring Quality in Construction! ⚫️🟢 How do we do it? We are an independent materials testing laboratory, @UKAS accredited to BS EN ISO/IEC 17025:2017. What is UKAS? UKAS stands for the United Kingdom Accreditation Service. It is the sole national body recognised by the UK government to assess and accredit organisations that provide certification, testing, inspection, and calibration services. In short, UKAS is the organisation that "checks the checkers" to ensure they are competent and impartial. Why it matters? When a company gets certified or their products are tested, UKAS accreditation guarantees that the evaluation was performed to the highest globally accepted standards. Government policies and major industries often require UKAS-accredited evaluations to ensure compliance, maintain supply chain trust, and reduce commercial risk. ✅ UKAS Accreditation ✅ Independence ✅ Impartiality ✅ Competence ✅ Trust ✅ Certified Confidence ✅ Consistent Quality ✅ Proven Competence ✅ Accurate Results ✅ Continuous Improvement ✅ International Standards ✅ Best Practice ✅ Risk Reduction ✅ Safety Assurance ✅ Regulatory Compliance Check out our Schedule of Accreditation direct on the UKAS website (UKAS number 8011) and don’t hesitate to contact TD for all your testing needs: 📞 01744 734 769 📧 [email protected] ⚫️🟢 #TD #tdct #ensuringqualityinconstruction #UKAS #8011 #testing #laboratory #site #soil #aggregate #concrete #asphalt #bitumen #materialstesting #earthworks #stabilisation #pavements #roads #highways #rail #railways #structures #construction #civilengineering #socialmedia #X #accreditation #certified #trust #confidence
