Geotechnical laboratory surveys of grounds:

We perform most of surveys, probes and analyses of grounds and waters at our own laboratory. Other, more complex, ones are conducted by specialised geotechnical and geochemical laboratories which co-operate with us.

  •     macroscopic analysis + examination of natural moisture,
  •     identification of bulk (volumetric) density,
  •     identification of specific density,
  •     sieve analysis (dry method),
  •     sieve analysis (washing-based method),
  •     aerometric analysis + sieve analysis,
  •     identification of consistency boundaries,
  •     determination of swelling indicators,
  •     determination of optimal moisture,
  •     determination of shear strength by means of direct shearing equipment,
  •     determination of primary and residual resistance as well as post water accumulation resistance of slipping areas by means of direct shearing equipment,
  •     determination of shear strength by means of tri-axial compressing equipment,
  •     determination of filtration rates by means of alternating gradient method,
  •     determination of filtration rates in tri-axial chambers,
  •     determination of compressibility modules by means of consolidometer equipment.
