Understanding Rammed Earth Construction: A Global Perspective

Rammed earth construction is an ancient building technique that is experiencing a modern resurgence, driven by increasing awareness of sustainable building practices and the desire for aesthetically pleasing, durable, and environmentally friendly structures. This guide provides a comprehensive overview of rammed earth construction from a global perspective, examining its history, principles, advantages, disadvantages, and diverse applications across various climates and cultures.

What is Rammed Earth?

Rammed earth, also known as pisé de terre (French for "pounded earth"), is a construction method that involves compacting a mixture of raw materials, typically including earth, gravel, sand, and clay, into forms to create solid walls. The mixture is dampened and then compressed in layers using manual or pneumatic rammers. This process creates a dense, strong, and durable material suitable for building walls, foundations, and other structural elements.
