Blending Robotics with Traditional Techniques

HTA uses cutting edge technologies to provide an accurate and clear stock condition for our clients. With MEWPS & the latest testing equipment to hand we have yet to find a bridge test too far.

Testing of Highway and Rail Bridges forms a large part of HTA's activities whether this be testing of concrete, steel, composite or any form of masonry bridges.

Concrete Bridge Testing

  • Cover meter surveys
  • Half-cell potential surveys
  • Resistivity surveys
  • Linear Polarisation Surveys
  • Crack Surveys
  • Visual + PI Surveys
  • PUNDIT Surveys
  • Carbonation depth surveys
  • Extraction of dust and core samples for subsequent laboratory testing

Steel Bridge Testing

  • Ultrasonic Thickness Surveys (determine amount of corrosion)
  • Weld Testing
  • Extraction of samples for determination of material type / strength / chemical composition (for welding specifications)

Masonry Bridge Testing

  • Removal of samples of masonery / mortar for strength
  • Make up testing
