The Importance of Laboratory Testing

  • Regulatory Compliance
    We provide UKAS-accredited laboratory testing which ensures compliance with local and national standards to maintain compliance.
  • Risk Mitigation
    Testing materials early can identify potential issues with materials before they are used, therefore allowing for early intervention.
  • Quality Control
    Laboratory testing helps toassess the quality of materials and workmanship, ensuring the project meets the expected standards for longevity and performance.
  • Cost Savings
    Identifying potential issues early and ensuring materials meet required specifications can help save on repair costs, delays and potential remedial work.
