Se apoya un edificio en una losa de cimentación de concreto reforzado que cubre un área de 12x24mts. el subsuelo es una arcilla que tiene una Resistencia a la Compresión Simple de 9.3 ton/m2. La presión en el suelo, debido al peso del edificio y a las cargas que va a soportar será de 11.37 ton/m2. en la base de la cimentación. Si el peso volumétrico del suelo excavado es 1950 kg/m3. ¿a qué profundidad deberá desplantarse el lecho inferior de la cimentación.
