  • We are the UKAS Accredited PTSI & NDT Experts

Asset Investigations

Multiple Teams with Multiple Skillsets available

HTA confidently investigate all structural elements and materials via NDT technology, exposure and breakout techniques plus sampling procedures, backed up with over 30 years of experience, supported by expert lab analysis.

Our Structural Investigation work falls into two main categories; first, how a structure is constructed and second the condition of the structural elements themselves. These lists are not exhaustive, but give you a flavour of the length and depth of the work we cover.

Need to determine how a structure is constructed?

If you need to discover not only the construction material but also the construction type, HTA offers a complete remit of works to provide you with all the data required to move forward with confidence.

  • Concrete Type - is it reinforced, pre-cast, post tensioned or steel encased
  • Concrete Strength - determination carried out via NDT and compressive testing
  • Steel Reinforcement - NDT to determine of bar depth and pattern including multiple layers
  • Steel Grade - determination of tensile strength via removal of samples
  • Metal Beams - determination of construction details by exposure
  • Metal Beam Weldability - chemical analysis determining carbon equivalent value
  • Metal Type & Grade - by removal of samples and metallurgical testing
  • Cavity Wall Ties - determining presence and correct spacing
  • Masonry Construction Details - determination via NDT, exposure and coring
  • Masonry & Mortar Strength - determination via sampling and analysis
  • Paint Inspections - adhesion testing plus sampling for lead content and type analysis
  • Timber & Wood - visual assessment, grading plus dry and wet rot surveys

Need to know the condition of structural elements?

Degradation, corrosion, non-compliant construction and change of use are the main causes of building problems and HTA offer a full remit of works to provide you with all the data required to move forward with confidence.

  • Reinforced Concrete - NDT to determine extent & rate of corrosion of embedded reinforcement
  • HAC Concrete - detection and condition of High Alumina Cement elements
  • Post Tensioned Concrete - NDT and sampling to determine post tension condition
  • Metal Elements - ultrasonic thickness technology for corrosion surveys
  • Welds - ultrasonic technology, MPI and DYE Penetration for inspection and testing
  • Cavity Wall Ties - determining embedment, condition and type
  • Masonry Condition - visual assessment to determine loss of brick facade and mortar beds
  • Paint Condition - visual assessment for debondment, cracking and failure
  • Timber & Wood - assessment for dry and wet rot surveys and insect attack
