The stability of existing or projected talus/slopes whether in rocky masses or in soil are investigated.

Some aspects of the investigation in rock talus are:

1. Geological characterization
2. Hidrogeology
3. Structural characterization

1. Task methodology
2. Definition of the family of discontinuities
3. Specifiied character of each family
4. Possibilities of breaking:

I-General characteristics

II-Layer breaks

III-Wedge breaks

4. Viable stabilisation of the talus/slope and/or protection of the buildingsat the foot of the slope under study.
5. Preventative and corrective measures. Methods for containing and anchoring the slope.
6. Proposals for solutions:
   1. bulonaje
   2. metal fencing
   3. netting backed with cables
   4. dynamic barrier
7. Evaluation of the possible danger: maps of the risks
