In the west part of Albania, near the Adriatic Sea there is a large area of very problematic soils as organic cohesive soils and fine sands under the ground water table. These soils have high porosity and are under consolidated. This region is characterized by a big development of motor-ways, industries, costal constructions and tourism.

We would like to present in this papers the laboratory and in-situ tests and studies performed by the laboratory “A.L.T.E.A&GEOSTUDIO2000” for the determination of the behaviour of these soils under static and seismic loads. We will also give some recommendations about engineering measures that should be taken for the improvement of these characteristics.
