Impact Echo Based Bridge Deck Scanner

Based on the Impact Echo method, our BDS is the most technically advanced vehicle towed system for structural condition assessment to date. No other system on the market tests for both top and bottom concrete deck delaminations, while performing over 60,000 impact echo tests in 1 hour on a 1 mile long deck. The BDS-IE-SASW system provides many benefits over traditional chain dragging of bare concrete decks including:

  • Highly accurate mapping of top deck steel delaminations to 1 foot or less
  • Detects bottom deck rebar delamination in areas without top delamination!
  • Thickness profiling of sound deck areas
  • Super fast testing time, practically eliminating traffic down time
  • Complete deck integrity evaluations with combined IE-SASW scanning
  • Highly accurate bridge damage maps for repair bids

Applicable On: Concrete Decks (ex: parking decks, bridge decks, industrial building floors, etc)

Test For: Top and Bottom Concrete Delaminations
