From the early days of building, when the entrance was on the roof of the house, to today, when mankind is returning to earthen construction, much has been learned about rammed earth and adobe, but there is still room for improvement. This work gives an overview of the physical and mechanical, acoustic properties as well as the durability, economic and ecological characteristics and the numerous advantages and disadvantages due to which the return to earth building has been accepted again. Soil water is particularly important for the consistency of the soil, as it influences the density, which is directly related to soil compaction. Lime, pozzolans and cement are the best known stabilizers, they are the most commonly used and mentioned in various studies, but whey, molasses, bio-fibers and vegetable juices are also mentioned in traditional construction. The service life of any structure depends on the intensity of the influences on the structure that lead to its wear as a whole or in parts. Mechanical, chemical and biological influences are those to which most buildings are exposed, not individually but in their combination. The work deals with different types of rehabilitation through the addition of materials, the joining of cracked parts, the reinforcement of walls with wooden elements, the rehabilitation through the use of plaster and the use of fibers, the cladding with bricks and the use of steel slag, the reinforcement with reeds or synthetic nets. At the end of the work you will find a table with an overview of the methods for repairing the walls of earthen houses with the possibility of applying these methods in Croatia.
