sMASH Impulse Response for flaw detection

For a long time, users of NDT systems have wished for a rapid, easy to use method for rapid screening of the integrity of structures. The s´MASH impulse-response test system fulfills this wish. The idea is to quickly screen a structure for flaws and identify suspect areas for subsequent detailed investigation, e.g. by the impact-echo test (using DOCter or MIRA d’Or), ultrasonic-echo testing (using MIRA or EyeCon), or by invasive inspection with drilled cores (using CORECASE).



With the s´MASH, rapid evaluation can be conducted for:

  • Detecting voids beneath concrete slabs in highways, spillways, and floors
  • Detecting curling of slabs on ground
  • Evaluating the integrity of anchoring systems of wall panels
  • Locating delaminations and honeycombing in bridge decks, slabs, walls and large structures such as dams, chimney stacks, and silos
  • Detecting the presence of damage due to freezing and thawing
  • Detecting the presence of alkali-silica reaction (ASR)
  • Detecting debonding of asphalt or concrete overlays and repair patches from concrete substrates
  • Evaluating the effectiveness of the load transfer system in transmitting frorces across joints in concrete structures
