This research consists of analyzing three unsaturated soils. Cohesion values are determined from variations in saturation degrees of specimens with specify density. This cohesion values will be used to analyze the effect on the supportive capacity of the superficial foundations. A Soil-Water Characteristic Curve is estimated form each soil index properties in order to realize this analysis. The cohesion values obtained from different saturation degrees are used to determine the superficial foundations design and to estimate each cost. Then make a comparison between the different results. This project includes the elaboration of laboratory tests, such as Particle Size Distribution, Atterberg Limits and Unconfined Compressive Strength, to permit the material classification and determination of the maximum shear strength. The methods and equipment used in these tests are according to ASTM methods corresponding to each test. Apparent cohesion is defined as the strength between the soil particles.
