Waterproofing and elevation profiling of a sub-surface drainage layer
Our practice in forensic engineering often includes investigating the causes of reported problems, documenting the extent and types of problems found, developing repair solutions, implementing a pilot (mockup) repair program, and monitoring the general implementation of the final repairs. This paper focuses on the somewhat unique problems associated with building a roadway above occupied spaces and the non-destructive testing we used to help solve those problems. This paper summarizes our efforts to identify, investigate, and repair the leakage problems. We outline relevant design details, describe the problem, review available resources, show representative results from a non-destructive GPR investigation program, and present the results of the repairs.
