Karst zones
The analysis of the
foundations of buildings
By this study the most vulnerable areas were determined by the occurrence of infiltration and fracturing areas presented, it is the same way mapping fissures predominant flow direction and infiltration was obtained.

Analysis of a sand
quarry for road building
Ukraine, 2016
Sand and the sand-gravel resources of the quarry were evaluated. With Borehole No. 2, the lack of commercial sand gravel stocks was confirmed.

GPR survey of fuel oil leaks
To assess the volume of fuel oil at the bottom of the lake, soundings from the water surface were carried out. The georadar was insulated with polyethylene from contamination and installed on sheets of foam. GPR operating in automatic mode (1 measurement per second) was dragged with the help of ropes from shore to shore. The survey showed that all depressions in the bottom relief and the deep-water part of the lake are filled with heavy fuel oil deposits of 1.5 to 5 meters.
