The most common building material is still brick with mortar. This is relatively expensive and sometimes has to be imported. The demand for a locally available building material that is sustainable and affordable is high. Hydraform blocks are an interesting alternative for a cheap building material, with resources that are largely available. Hydrafoam Blocks are made out of sand and cement. This technique is based on mixture of sand and 10% cement which makes these building blocks cheaper than the traditional building materials. The only problem with Hydraform blocks is that the machinery necessary for the production are relatively expensive. Due to this costs not many communities are able to afford the machines.
