The population and urbanization of Kenya are increasing, and because of this the Kenyan government has resolved to create 150.000 new houses annually. The quality of housing in Kenya is low, especially in rural areas. The prices of houses should be as low as possible so that they will be available to a large group of the population. A new quick and cheap building method would assist the government in achieving its goal. Precast technology is a possibility to perform a quick and cheap building method. Another advantage is the relatively good quality of the concrete, because of controlled circumstances. For this purpose new available techniques are investigated to reduce costs of pre-casting and increase the quality of housing.
