- Standard and Core Penetration tests;
- plate loading test (600-5000 cm2);
- pressiometry;
- pebble cobble shearing test with wedge pushing-out method;
- test pit and drill hole filling and inflating; extraction of groundwaters for soil permeability ratio fixing;
- monitoring observations of water table (in boreholes) and soil temperature (in permafrost zone).
