Durability

Estimating the expected working life of construction products has long been an integral part of the BBA assessment and certification process. Using accelerated ageing techniques, we simulate exposure to aggressive elements that a material will see in service during its lifetime. This information can be used to estimate and predict the service life of the product or identify potential weaknesses in the product’s design.

Key tests are carried out before and after the ageing process to assess if the performance of the product will change over time.

Our Key Facilities:

  • Environmental chamber
  • Fluorescent ultra violet chambers (with spray and condensation)
  • Heat ageing ovens
  • Salt spray chamber
  • Various endurance and thermal cycling facilities
  • Xenon arc weatherometer

From our custom-built testing centre, we carry out the following durability tests:

  • Cyclic fatigue and endurance (to look at movement over cracks and joints)
  • Exposure to alkalis or other chemical agents
  • Freeze thaw cycling (down to -30°C)
  • Heat ageing (between 40°C and 1500°C)
  • High humidity and temperature exposure
  • Hygrothermal, thermal shock (combined heat, water spray and freeze/thaw)
  • Salt spray corrosion
  • UV radiation (xenon and fluorescent lamp)
  • Water exposure at elevated temperatures

Durability testing is relevant to the following product areas:

  • External Thermal Insulation Composite Systems (ETICS)
  • Highways and Bridge Deck Waterproofing
  • Insulation
  • Pipes and Drainage
  • Roofing and Breather Membranes
  • Tanking and Damp Proofing
  • Windows, Doors and Rooflights (including hardware and profiles)
