Earth
The composition of the earth to be rammed should be approximately 70 % sand, 25 % clay and 5 % lime. If the local earth composition varies greatly from these proportions, the mixture can be corrected and stabilized by adding more sand, clay or lime as appropriate.

Foundations
These are 300X500 mm 8% earth: 92% cement strip foundations, constructed of manually compacted, alternating layers of 70 mm earth cement and 70 mm stones. The wall formwork can also be used for the construction of the foundations. (Fig. 17)

Upper Foundations
The upper foundations consist only of earth cement - there are no layers of stone. Their function is to protect the rammed earth walls from erosion and damp. (Photo 14)

Walls
The walls are built using rammed earth formwork. These components have the following dimensions: 1100 mm high by 2000 mm long and 300 mm wide. They are laid in overlapping courses as in any typical brick wall. (Photo 15)

The earth is rammed in successive 70 mm layers. The horizontal forces generated by earthquakes are counteracted by reinforcing buttresses located at intervals where there are no partition walls to carry out this function. The walls are constructed first, the holes for the windows and doors are cut out of the solid wall afterwards.
