A mechanical device utilizes pressure to form blocks from stabilized earth. These blocks, composed of compressed soil and a stabilizing agent such as cement or lime, offer a sustainable building material alternative. An example would be a hydraulic press that compresses a mixture of soil and stabilizer within a mold to create a solid, uniform block.
This technology offers significant advantages in construction, including reduced environmental impact due to lower embodied energy and local material sourcing. It also provides thermal insulation, soundproofing, and fire resistance. Historically, rammed earth techniques have been utilized for centuries; however, mechanized production offers improved efficiency and consistency, making it a viable solution for modern construction needs, particularly in affordable housing projects.
