Penetrometric surveys in Laos

Contracting authority :          Nam Theun 2 Power Company (NTPC)

Prime contractor :                  EDF CIH

NTPC commissioned Sol Solution to carry out penetrometric tests in an earth dam at the Nam Theun hydroelectric plant in Laos.

In 9 days, 82 PANDA® penetrometric tests were carried out at an average depth of 7 metres in a sandy-clay soil, according to a regular and tight grid of 3 lines spaced 2 metres apart (see photo).

The data collected allowed the drawing of resistance profiles revealing the compactness mapping of the structure. The client was provided with 2D and 3D models.

This mission demonstrated Sol Solution's capacity to investigate in a faraway country with light equipment adapted to local constraints.
