The saved up experience allows to judge ample opportunities of GPR method for nondestructive control of operational reliability of hydraulic engineering and transport constructions. The GPR method is intended, first of all, for quality standard of a condition of constructions. High sensitivity of this method minor alterations in a structure, structure and a condition of materials of a design of a construction, do its irreplaceable for revealing the defects collecting, external loadings developing and shown under action and causing decrease in durability and bearing ability of designs as a whole. On examples of results of georadar-tracking inspection of concrete fastening of a pressure head slope of a soil dam of the Nizhniy Novgorod hydroelectric power station and a site of the October railway high efficiency of application of a method for revealing and estimations of geometrical parameters of defects of hydraulic engineering constructions and is shown to an earthen embankment of a railway way.
