Mud bricks are made from earth that has a certain ratio of clay. The clay acts like natural glue, gluing all the components in the soil together.

How To: Make Mud Bricks

Step 1

First pour water into a mixing container then sprinkle the soil into the water until it reaches the surface. The water to soil ratio is about ½ volume water to 1 volume soil, add more water as needed.

Leave the soil to soak up the water this helps separate the clay particles & makes it easier to mix. If the soil is fine in texture it may be 2-3 minutes if more lumpy or clayey it may take 8 - 12 minutes or even more.

earth
The earth around you has different proportions of sand, silt and clay.
Clay is an important ingredient to building strong mud bricks.

Step 2

Mix the soil until it is smooth. At this stage we mix in sand because our soil is rich in clay, the mud's natural glue, which alone has a tendency to crack when dry.

Sand is another important ingredient for building strong mud bricks.

Step 3

After mixing the sand and adding water as needed till a smooth consistency similar to hummus we mix in straw. Also mixing and adding water as needed till a stiff hummus like texture.

straw
Straw adds tensile strength to the mud bricks.

Step 4

The mud is now ready to put into clean and wettened mud brick frames and immediately pulled off so leaving a beautiful mud adobe brick ready to be dried in the sun.
