Abstract: The use of bio-based materials is becoming a growing need, especially for sub-Saharan countries. Moreover, in a context marked by the level of land pressure of Dakar region in Senegal, the city of Diamniadio is chosen by the Senegalese authorities as an administrative city seems relevant because of its proximity to Dakar. However, the land of this area formerly reserved for market gardening create some difficulties for its use in the setting up of buildings. That’s the reason why, we proposed this study which main objective is to propose a method of implementation of this land in the construction by improving its properties to the Typha Australis which is a wild and harmful plant. So, after a characterization of the earth that confirmed its clay and plastic character with a fineness module of 1.32 and a plasticity index of 20.47%, we mixed it with Typha Australis to analyze its mechanical properties. The experiment with the press shows a mechanical resistance to compression of 1.08 MPa for the soil alone and 0.71 MPa for that treated with 10% by mass of typha through 0.89 MPa for the soil treated with 4.48% of crushed typha. These values are sufficient for land use mixed with Typha Australis in the walls of the buildings. This gives this study a double impact, namely the development of the land of Diamnidio and Typha Australis.
