Earth has been used as a construction material in every continent and in every age, largely due to its versatility and widespread availability. It is one of the oldest building materials. The use of earth on-site as a building material saves manufacturing costs, time, energy, environmental pollution, and transportation cost. As a result of Operation Murambatsvina (Cleanup campaign carried out in 2005) in Zimbabwe, the percentage of squatters has increased. A solution has to be found to provide sustainable low-cost housing for these squatters that is ‘eco’-friendly and will preserve the environment for future generations whilst catering to the needs of the present inhabitants.
