Mud bricks are made from a mixture of soil, water and straw that are mixed together and kneaded before being set into molds and allowed to dry. Materials needed include topsoil, water, straw, sand and a mold in the shape of the bricks you wish to create. The entire process to create mud bricks takes about two weeks.

  1. Combine the basic ingredients for the mud bricks

    Mix water and topsoil until you have created a thick mud, and add straw to the mixture. You should aim to use about 1/2 pound of straw for every cubic foot of mud. Break or chop the straw into small pieces before adding it to the mixture.

  2. Knead the mixture

    Over the next four days, knead the mud mixture with your bare feet. When the mixture begins to ferment at the end of the four days, let it sit undisturbed for a few days.

  3. Pour the mixture into the mold

    On the day you wish to form the mixture into bricks, knead it once more with your feet. Pour the mixture into the mold, and let it sit for at least 20 minutes.

  4. Remove bricks from the mold

    Prepare a drying surface for your mud bricks by layering a floor with sand and straw. This prevents the bricks from sticking to the floor. Let the bricks dry for a week to finish them.
