GEOLUCE – La force de la terre pour bâtir

Manufacturing

The rammed earth has been used for millennia in construction. Before the advent of cement, lime was used to make earth mortar water resistant.  The traditional wet earth mixed and tamped technique  (adobe) allowed  producing a material to build ecological housing  in several parts of the world. However, these houses are built with earth or clay, vulnerable to water, causing disasters during rainfall or rising damp. In 1958 a team of technicians in Bolivia, decides to help a housing project with earth concrete. They develop the earth stabilization  method  with cement and compression. They made the first hand press "Cinva Ram" and pre-manufactured stabilized earth concrete blocks.

Later, other hydraulic or manual machines have been introduced to make stabilized earth blocks. However, static compression (manuel  and hydraulic) quickly showed its limitations. The mechanical strength obtained was insufficient, resulting in the distrust in earth materials. More-over the inadequacy of hydraulic technology showed in the experimental operations in hot countries.

Based on this experience GEOLUCE has developed the manufacturing process of rammed earth with electromechanical dynamic compression. With the acceleration of hammers, the tamping presses develop 8 N / mm ²,  by pounding on the entire block (Marshall) avoiding hyphenation. To produce equivalent power, static compression requires a pressure of 150 bar and need  heavy and powerfull hydraulic systems.

TheGEOLUCE manufacturing process is the only  able to produce industrial quantities of materials and perfect quality concrete earth stabilized with all available soils.
