For the soil testing component of the project we collected soil from nearby villages in order to test and compare the different types of soil found on the island. This data found from the soil tests will assist us in coming to a conclusion about which soil will best suit our needs as well as the amount of stabilizing (adding of sand and cement) needed for the production of the compressed earth blocks. Once we have chosen a soil that we want to use, we can make a series of test blocks and tiles that use various rations of soil, sand and cement.
