Where ever there were mangroves, estuaries and today homes and large buildings stand, is Guayaquil. The center and south of the city are built on soils composed of clay, silt and sand today is not a secret to anyone, nor is that these sites are not ideal for building, unless, of course, that apply good foundation.
Local geologists say there are sectors under which it has been found layers or strata of clay and sedimentary material, which reach 30, 40 and up to 100 meters deep. Be located in an area of estuary, is the cause.
Stalin Benitez, geological engineer with a doctorate in the subject, states that the city is based on three geomorphological domains (DG) and that really worries is ranging from the hills El Carmen and Santa Ana to the south and southwest, and it includes areas as far as the estuary Salado comes as Urdesa.
“Research and study of the dynamic behavior of the subsoil and microzonation of Guayaquil,” in which he participated this technical along with fellow specialist Xavier Vera in 2005, referred to this area as ‘Plain estuarine deltaic’, “because all the islands are south have been deposited by the Guayas, in the mouth, which forms a typical delta, “said Benitez, who estimates that 65% of the city is built on these soils (I).
