Impact Echo Test Grid
Impact Echo Test Grid
(OP)
We are looking to use an impact echo method to check an existing slab for thickness, as well as cracks and voids. The idea was to set up a grid, an analyze each grid center. Is there anywhere that states what size grid is recommended for this type of application? I was thinking 1ft x 1ft grids for a 160 sq ft area.

For an approx 13'x13' area I think that a 1' grid is appropriate for IE.
Not sure if there is a stated recommended grid spacing. Maybe check ASTM or ACI, they may have some guidance.
