 Pit tests

Pit excavation for determining the character of a terrain

This rapid and low cost examination technique enables us to reach moderate depths of 3-4m in terrains excavated by mechanical means in soils that are preferably cohesive and without underground water.

By observing this terrain we can recognise and identify the different lithological units, study the stratigraphy and check the strength of each of the units.

We can also obtain the parameters which, although they are qualitative, are also indispensable for classifying the geomechanical behaviour of the units observed:

- The excavatability or rippability of the lithological units
- The stability of the walls of the excavation


Lastly this type of investigation enables us to obtain soil samples from the required levels for a laboratory analysis of the ground.
