Excerpt from the geophysical survey report dated January 1, 1994, produced by the company TECHSOL (reference 93 11 408/14)

Methods of Operation :

The study was conducted in two phases : bibliography and synthesis of existing regional documents of and completion of 9 electrical soundings beginning from a known reference bore-hole and heading towards TROARN all the way to the DOZULE site.

Conclusions and recommendations :

The study conducted on the sector of Dozulé has provided a sectional forecast of the terrain in the 0-200 meter slice situated beneath the butte.

To measure the foundations of the job... the influence of aquifers, soft or brackish water, must be equally considered, so that the mechanical firmness of the soils in the work area will function under all foreseeable constraints for this type of project, particularly with Oxfordian clays which exhibit poor characteristics.
