Under the action of long-term rainwater erosion, wall erosion and collapse caused serious and irreversible damage to historical relics. Therefore, it is necessary to pay attention to the erosion resistance of the rammed earth Great Wall. The Thatched Brick Pavilion, a collaboration between Danish studios LETH & GORI, Rønnow Arkitekter, and CINARK, exemplifies sustainable design at the 2023 UIA World Congress of Architects. This innovative structure prioritizes low-carbon construction through its unique building system.

Though rammed earth construction has been modernized, North America has not yet adopted building codes for it. In Australia and New Zealand, where rammed earth houses are more common, codes have been formalized. In fact, research conducted in earthquake-prone New Zealand suggests that monolithic earth walls withstand earthquake conditions better than brick or block walls.
Rammed earth example projects
Once the earth is ringing, then you can add the next 4 to 6 inches of soil. It is possible to ram too much, which will cause stress on the wooden form. While earthen mixtures can be mixed by hand, it's more common to use a tractor or a tiller.
Modern Rammed Earth Method
She also integrates recycled polyiso insulation into the middle of rammed-earth walls to minimize thermal bridging. In Australia and New Zealand, where rammed-earth houses are more common, codes have been formalized. Rammed earth buildings are buildings formed by the artificial ramming of natural soil. Rammed earth is a renewable and clean energy raw material1,2 that is able to meet the current carbon emission requirements3,4,5.
Learn how to measure, cut, and build window casing made of cellular PVC, solid wood, poly-ash boards, or any common molding material. “As we face the dangerous and deep crisis related to climate change, we absolutely and urgently need feasible alternatives,” Dethier tells Curbed in an email interview. So let’s get talk about the nitty-gritty details of rammed earth. Every design project begins with site analysis …start it with confidence for free!. The historical significance of rammed earth isn’t just a reflection of its durability but also an insight into human innovation.
Erosion protection mechanism of biological crusts on the rammed earth Great Wall
Under long-term action, CaCO3 will be produced if lime is added to the rammed earth in the wall. Diluted hydrochloric acid with a concentration of 0.5 mol/L was added to crust layer sample A1, pulverized layer sample A2, parent soil layer A3, and no foaming occurred. The production process itself is eco-friendly, utilizing heat activation and solar power, with plans for a closed-loop recycling system in the future. CornWall panels boast not only a beautiful aesthetic but also a negative carbon footprint, storing the CO2 sequestered by the corn during its growth. Biodegradable and endlessly reusable, these panels can be simply peeled from walls and reinstalled elsewhere, eliminating waste and creating a truly sustainable design solution. NAREBA is participating in Research opportunities that enhance our understanding of how contemporary rammed earth walls perform.
Tips On Designing Solar Ready Homes
In a basic sense, rammed earth is a kind of human-made version of sedimentary rock. Earth is compacted layer by layer in a formwork, which is then removed, revealing a beautifully stratified surface. David Easton, President of Rammed Earth Works, has been building with rammed earth for the past four decades. I sat down with him at his workshop in Napa, under a smoke-filled November sky, to talk with him about his experience bringing this ancient material into the modern era. Whatever mix you decide on, it is always advisable to make up test blocks of various mixtures from your site soil with whatever additives are necessary, and see which blocks perform the best.
Characteristics of the local erosion resistance of the rammed earth wall
A dramatic roof overhang with Douglas Fir soffits and rammed earth walls frame the entrance. Other than the walls, you might not even be able to tell you're in a rammed earth home because in most other ways, it resembles a conventionally built house. The foundation, roof, electricity, plumbing, and decorative features are installed in the same way as other houses. On the next page, we'll take a look at the disadvantages of rammed earth construction.
For more on rammed earth homes, including links to builders who specialize in this type of construction, see the next page. In the summer, when high air conditioning use strains the grid, solar can be useful even in the middle of the day. Denholm says that as solar continues to drop in price, installing solar that is curtailed regularly can still be cost-effective. “Throwing away some amount of renewable energy can absolutely make economic sense,” he said. The Great Wall of Shanhaiguan is adjacent to the Bohai Bay, which has a temperate continental monsoon climate and four distinct seasons.

Earthbag buildings are more water-resistant than those made with straw bales, making them suitable for earth-bermed and below-grade structures. If your site is susceptible to flooding, earthbag building is one of the best options - after all, sandbags have a long history of use for flood control. Just use an appropriate fill material, such as gravel, in lower courses. Set on a concrete foundation, the rammed earth construction is composed of earth, sand and clay to create a wet mixture that is placed in between flat panels to harden. The studio said this technique allowed for easy, efficient and affordable construction on the site.
Passive cooling strategies like strategically placed shutters and a sweeping roof ensure a comfortable environment for artists and visitors alike, reducing reliance on energy-intensive air conditioning. This unique arts hub serves as a model for future projects, demonstrating how innovative design can foster a vibrant artistic community while respecting the environment. Architect Emilio López‘s Casa Quinchuyaku sited on the slopes of Ecuador‘s extinct volcano Ilaló prioritizes sustainability throughout its design.
Then comes the hard part — flipping the bucket and removing the form so that what remains is a structure fit for a king, or at the very least, a sand crab. Rammed earth homes are like building sand castles, but without that tricky step of flipping the bucket. In response, California has cut back incentives for rooftop solar and slowed the pace of installing panels.
So now for everyone that’s up in this community where you all lost your livelihoods, there are now 40 jobs to build houses with block walls that won’t burn next time. I don’t seem to have the ability to craft that whole thing into the compelling argument that would get someone to invest in it but it sounds really logical. Jaeger lives with his wife, Wren, on over 10 acres in the hills of the Ozarks. On this land, they have created a permaculture-based homestead where there was once just land ravaged by the logging industry.
