INTERLOCKING STABLIZED SOIL BRICKS ISSB |
Soil stabilized bricks have been around since the 1950s. First made in India, they have been used extensively around the world. Dr. Moses Musaazi of Makerere University, in Kampala, Uganda, has adapted the machine and technique for Ugandan soils and sells the machines. They are made in Kenya and can be delivered to Uganda within a week of ordering. The concept is simple: take non-organic soil, add a stabilizer (we use cement), add a little water to make it sticky, and press it in a mold at 90 psi to form bricks. This sustainable technology produces bricks stronger than burnt bricks without the deforestation. |
The machine comes in two styles: a rectangle for walls and straight surfaces, and curved (seen above) for making water tanks and latrine pits |
Partnering for Africa's Future is partnering with several people and organisations to get them the machines and the training. Spring for Life has acquired a curved and rectangle machine and is using it to build orphanaes and a village for refugees. They are also using it to build housing for workers on a large farm project. |
The soil and concrete mixture is put into the form |
Pressed |
And out comes the interlocking brick |
The interlocking bricks are cured for 4 hours and are then ready to use |
