With a driving emphasis on the use of eco–friendly floor materials, there is resurgence in recent years toward adobe
flooring. This unique floor type particularly popular in parts of the world where people are concerned about a rapidly
deteriorating environment. Adobe structures and flooring has a particular appeal in buildings aspiring for a natural, rustic
appeal.
Adobe has several advantages in that it is environmentally friendly and a sustainable architecture. Adobe is
naturally available, renewable and efficient. Adobe flooring is used in many parts of the world. Examples of adobe, used in
architecture, are common in the American Southwest, Latin America and the Middle East. Adobe is the perfect building material
for hot climates. It requires no timber, reinforcing its choice as an eco–friendly selection; it is easy to work with
and has a pleasing appearance.
An ideal mix for Adobe flooring is 30% clay, fine sand and silt. Straw or Psyllium husk is added Adobe floors to give the
mixture additional binding property, increasing its strength and reducing cracking. Initial tests using Portland cement
mixtures indicated that the soil was somewhat expansive, but cracking of the floors is prevented by mixing with sand. Adobe
flooring can be finished with two or three coats of sealer to obtain a high gloss finish.
Adobe floors carry the rich color of natural earth. The earthen raw materials have low thermal conductivity and high
density making them passive solar devices. Adobe flooring captures and retains heat throughout the day and releases it at
night. Nonetheless, adobe floors are known for their cool factor hence the traditional choice in several tropical countries.
