Building Investigation Experts
Confidence built in
HTA investigate all building 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 Building Investigation work falls into two main 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.
Determine build construction
Discover not only the building construction details but also the 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 condition of build elements
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 - HAC Concrete
Detection and condition of High Alumina Cement elements - RAAC
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
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
ssessment for dry and wet rot surveys and insect attack
