Engineering-geological surveys

•   Subjecting solid rocks to drilling operations:

< 30 metres – the diameter of core – 42 mm;

< 100 metres – the diameter of core – 34 mm;

Field equipment:  Minex, Winkie Drill

•  Determining the density ratio of soil and unstable rocks, such as clay, sand, and gravel: the depth of penetration: <5 m;
•  Determining the density ratio of soil and unstable rocks, such as clay, sand, and gravel: the depth of penetration: <10 m (under favourable geological conditions);

Field equipment: portable dynamic penetrometer, FD-645, HEAVY-DUTY

Geological survey

• Geoogical mapping
  • Existing maps (geological, tectonic, geomorphological, et) in foundations. Classification scales:
  • 1:50 000;
  • 1:25 000;
  • 1:10 000;
  • 1:5 000;
  • 1:2 000

• Digital database of the maps id foundation materials

Creation of a digital model of existing maps in foundation materials and their classification;
