APPLICABILITY OF RADAR SUBSURFACE PROFILING IN ESTIMATING SIDEWALK UNDERMINING

The results of an evaluation of the applicability of the geophysical technique of radar subsurface to estimating the extent of sidewalk undermining are reported. It was found that there is a distinct difference between the observed radar-echo patterns from a nonundermined sidewalk and those from an undermined sidewalk. Therefore, it is feasible to determine from a radar scan the length of sidewalk that is undermined. It is also feasible to determine the approximate depth of voids beneath an undermined sidewalk, although this may sometimes be difficult to achieve. (Author)
