Rammed Earth:
Is a wall system made of earth, water, and sometimes cement tamped in 8" layers inside of
removable forms.

Compaction is the force that turns soil into sedimentary rock. In rammed earth, compaction occurs through impact with the force of a tamper falling time and again on a recipient soil mass.This impact not only compresses the soil, but also encourages the individual particles within the soil to realign themselves. The jarring action of the tamper forces the particles into the tightest possible molecular and mechanical configuration.

Rammed earth construction can utilize local natural materials and provides excellent thermal mass.
