Building Investigations

Confidence you can build on

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

Building Investigation Services across Wales - HTA

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

Building construction Determination

Discover construction details plus construction type, Employ the HTA Full Service Suite and remove the management of multiple companies and various operators on site.

  • 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

Determine the condtion of the building elements condition.

Degradation, corrosion, non-compliant construction and change of use are the main causes of building problems. Employ the HTA Full Service Suite and remove the management of multiple companies and various operators on site.

  • Reinforced Concrete
    NDT to determine extent & rate of corrosion of embedded reinforcement

    Detection and condition of Reinforced Autoclaved Aerated Concrete
  • 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
