A rammed earth wall is a wall built by forcing (ramming) a mixture of subsoil with gravel, clay, sand, silt, and a stabilizer (if any) into formworks. For a sturdy wall, these aggregates are mixed in the proportions of 30 to 40% clay soil and 60 to 70% gravel, sand, and fines before ramming. In the rest of this article, I'll discuss how. Furthermore, check out our Storyrock project profile for another beautiful example of Rammed Earth. And as always, you can email us at

Rammed earth walls have the lowest environmental impact of all the building techniques currently used in the commercial industry. Cured rammed earth also has a high thermal mass which means it absorbs heat during the day and releases it at night - majorly reducing heating and cooling costs and energy. Rammed earth, is a technique for constructing foundations, floors, and walls by using natural raw materials. Materials like earth, chalk, lime, or gravel. It has a long history stretching back to about as early as humans were making buildings with evidence of it being used as far back as 8000 BC in the Fertile Crescent so if it was good enough.
Rammed Earth Walls What You Need to Know Before Installing Colorado Hardscapes
Rammed earth walls are constructed by ramming a mixture of gravel, sand, silt and a small amount of clay into place between flat panels called formwork. Stabilised rammed earth adds a small amount of cement (typically 5-10%) to increase strength and durability. Rammed earth provides excellent thermal mass but limited insulation. Rammed earth construction is the process of ramming a mixture of aggregates, like gravel, sand, silt and clay into a formwork to create walls. When the earth is dry the formwork is removed to reveal solid monolithic walls. Rammed earth is an ancient form of construction, generally seen in drier hotter parts of the world. Although many rammed. Rammed earth is one of the oldest methods of constructing walls and still holds great potential for modern earth construction.One aspect of this potential is the gift of its colors and layers. Rammed earth construction is a structural building method of compressing a sandy mixture into a hard sandstone-like material. Rammed earth walls resemble adobe construction. Both use soil mixed with waterproofing additives. Adobe, however, requires dry weather so that the bricks can harden ( cure) enough to build walls.

Part E - Resistance to the passage of sound. • Rammed earth walls provide effective acoustic separation. • Where floors are supported by separating (party) rammed earth walls, design detailing should follow the norm for other solid masonry walls, but with the additional requirement to accommodate moisture movement. Rammed earth is composed of clay, sand, gravel, and a small portion of cement to act as a st. In today's tutorial, we learned how to make a rammed earth wall!
Qualification. We are the inventors of both insulated and structural rammed earth, and have dedicated more than $2M on SIREWALL R&D. We are the undisputed global leaders in this niche market. As a result we know best what to do—and what not to do—in project specific circumstances. A rammed earth wall has a lot of thermal mass and can easily be an airtight wall system, but it has no inherent insulation value (see Thermal Mass vs. Insulation sidebar). The overall energy efficiency of a rammed earth wall system will depend on the insulation strategy. Insulation can be placed on either the interior or exterior of the wall or.
Rammed Earth Rammed earth, Rammed earth homes, Natural building
The only downside of rammed earth construction is its susceptibility to water and low compressive strength. However, modern rammed earth walls have ways to deal with these challenges, including: Using cement-stabilized rammed earth: Using 5 to 10% cement to stabilize rammed earth increases its compressive strength from 2.68 MPa to about 9.30. The number of rammed earth construction crews is growing, but a house can also be completed by an owner without professional help. Finding the Right Soil Mixture. In the days of building the Great Wall of China, people just rammed some earth and called it a day. Walls either stood the test of time, or they didn't.
