The paper presents the successful application of the high resolution seismic reflection imaging (HRS) to survey of the shallow subsurface environment. Recent progress in this domain has been made both as regards to measurement systems, signal processing and interpretation techniques. It is shown that HRS may be considered as a particular CND technique, adapted to detection in ground. The enclosed field examples cover different civil engineering applications, such as stratigraphy of the shallow subsurface, detection and location of underground voids and detection of collapsed and filled-in voids. It is shown that HRS may be successfully used for the evaluation of risk of cavity collapse, as well as for verifying the quality of filling of collapsing cavity with cement mixture.
