basic principles of oldfashioned rammed
Earth has been used for building homes since time immemorial. One method of use, beyond
others, and which was understood by the Romans, has been preserved by tradition to modern
This technique incorporates ramming slightly moist, specifically selected soil, without needing the
addition of straw or other material, in between movable forms, and is called rammed earth.
Rammed earth building is a dependable building component when correctly worked with and is
admirably adapted to those who want to build a green and environmentally friendly structure.
Earth has been utilized in the building of building walls by virtually every nationality of people
whose history has been recorded. Two techniques have stood the test of time, they are the
rammed earth method and the adobe construction method.

Rammed Earth
Rammed Earth walls are built by the simple technique of ramming selected earth consisting of a
suitable amount of moisture between removable frameworks. These forms can be taken away as
soon as the earth is compacted. Different rammed earth builders have even used such items as
rectangle-shaped shaped bags, lengthy cyclinder type bags and even old car tires to be the basis
of the structure's walls.
Not only is this sort of construction environmentally friendly, but it can be extremely inexpensive,
especially if your land has the dirt right there.
Selection of Building material
The most vital considerations in rammed earth are the selection of a correct dirt having:
a. the proper amount of moisture;
b. and a careful compacting of the earth.
Pure clays are not advised because of excessive shrinkage, and sandy material will not bind.
Most average earths are suitable, or may be made so by blending. Nonetheless, according to
many builders, all biological or other matter dependent on decomposing should be eliminated.
If the earth forms into clods when excavated or if the sides of a ditch remain firm, it is an
indication that the soil may be fit for rammed earth walls. The soil in a footpath which stays hard in
wet weather is promising material. Earth in which wheels have formed ruts may also be suitable.
Difficulty in squashing a dry clump of soil between the fingers is another indication of suitability.

Frequently the soil from cellars or trenches is fit for building or may be quickly made so by
blending with other soils.
If earth found on the proposed building site is not of the proper composition, it may be made
suitable by mixing it with some soil from another area.
