Building a house made of soil – forgotten technology of landbaby construction

The idea of building a house out of soil may seem archaic in today’s world of modern construction, where steel and concrete rule the landscape. However, the landbaby construction method, which dates back thousands of years, has a lot of promise for building environmentally responsible and sustainable homes. Once commonplace in many cultures, landbaby construction builds strong, cozy homes using locally accessible materials and age-old techniques.

Earthen or adobe homes, commonly referred to as landbaby houses, are built with a combination of soil, water, and organic materials like grass or straw. This mixture is frequently applied directly to a wooden framework or formed into bricks. As a result, the interiors are kept warm in the winter and cool in the summer thanks to the structure’s inherent insulation. In addition to offering superior sound insulation, the thick walls have a distinct aesthetic appeal that complements the surrounding natural environment.

The minimal environmental impact of landbaby construction is one of its most compelling advantages. Compared to traditional building methods, the carbon footprint is significantly reduced because the materials are easily obtainable and require minimal processing. Furthermore, the building process itself uses less energy because it frequently makes use of basic hand tools and generation-old methods.

By resurrecting the long-forgotten technology of landbaby construction, we can build in harmony with the environment and reaffirm our connection to the knowledge of our ancestors. This traditional approach offers a practical—and frequently better—alternative to contemporary construction methods in a time when environmental stewardship and sustainability are becoming more and more important concerns. Whether for a large family home or a small cottage, building with soil is an example of the human craftsmanship’s enduring ingenuity and resilience.

The age-old practice of "landbaby construction," or building a house out of soil, is a little-known but incredibly sustainable way to build a long-lasting, environmentally friendly home using natural materials. This age-old method, which blends organic and earth materials, gives contemporary builders a means to honor the knowledge of our forefathers while lessening their influence on the environment. We can build enduring, aesthetically pleasing structures while encouraging sustainability and ingenuity in modern building by reexamining and modifying these time-tested methods.

Examples of zemstvit buildings

The primary building material used in the landbrow construction technique is regular earthen soil, which is used to construct walls and supporting structures. There is a long history of using this construction method. It is possible to find comparable structures in ancient Rome, Morocco, China, and other African nations. Although earthbite construction is no longer as popular, the masters are still occasionally returning to it.

An example of an earthbite building is the Priorat Palace in Gatchina, which was created in 1799. Its walls cost more than 220 years without repair. A two -story building with a turret 18 meters high is made of the ground, the foundation is laid out of a bot (building stone based on limestone, sandstone and granite). The thickness of the walls of the palace varies between 60-80 cm, decreasing to the ceiling. The walls of the walls have gravel fractions up to 7 mm, fine sand, earthen dust, clay. Straw, grass and other organic additives are absent. The palace was built by laying the soil in the formwork and its tamping, followed by plastering of dried walls.

Features of technology

The landbaby construction method was initially based mostly on manual labor. The walls are constructed using formwork and a pre-prepared earthen mixture that was layered inside the form. Each layer is typically no thicker than 15 cm, after which it is thoroughly compacted, given a new shape, and the manipulation process is repeated. Act in this manner until the walls are the appropriate height. As soon as the next level is constructed, the lower formwork is removed. For land traffic these days, specialized pneumatic installations are employed.

Advantages and disadvantages

Earthbite technology offers significant cost savings. Building an earthen wall is five times less expensive than building one out of brick or concrete. Subject to the use of auxiliary installations, labor costs, fuel consumption, and electricity costs are also lower. Since the technology is non-waste, the land that is removed in order to dig a trench for the foundation is used in business.

Additional benefits of the approach include:

1. Low thermal conductivity of walls. In the cold season, in the ground -bit buildings, there is always heat if there is a standard heating system. In the heat there is no need to use air conditioners – the premises are quite cool. The optimal microclimate parameters are achieved thanks to the microporous surface of the walls, which also help maintain humidity in the most favorable limits for humans.
2. Non -combustibility and safety. Earth -bit houses are not afraid of fire and do not support burning at all. They are environmentally friendly, since the whole structure is based on natural substances and does not contain toxic elements.
3. Strength. Over time, zemstvity buildings tend to strengthen. After 20 years, the house will not concede the concrete by reliability and will become more durable than a brick building. This explains the huge period.

These kinds of structures have very few drawbacks. They necessitate the implementation of excellent waterproofing techniques in addition to the construction of an exceptionally sturdy foundation. Only during the summer can all construction phases be completed; otherwise, the walls won’t be able to dry properly. The technology of the past has undergone some modifications due to the modern approach, which have mitigated its drawbacks. For instance, walls are built using construction equipment, and supporting structures are swiftly formed using specialized sliding formwork.

Requirements for materials

Not all soils can be used for construction. The only way the house will be sturdy and long-lasting is if the composition is balanced. For earthbuilding, the land itself, along with clay, sand, and filler (typically gravel), make up the majority of the soil. Up to 50–70% of the composition should consist of sand, with the remaining ingredients being roughly equal. If there is any remaining organic matter in the ground, it must be completely removed because otherwise, mold and decay will start inside the walls.

The appearance of the soil can be used to determine its suitability for development. The ideal soil to use is sandy or sandy soils with a reddish, brown, or yellowish hue. Another good soil type is a loam, whose composition can be changed by adding sand. The strength of the walls will be positively impacted if a small amount of road dust (estimate) is incorporated into the ground.

Right before the structure is built, the soil is prepared. Utilize the dirt left over after excavating drainage channels and trenches beneath the foundation. She is covered with a film right away to prevent her from drying out. Although it is not required, a small amount of cement (up to 3%), is injected into the ground to strengthen the structure. Nonetheless, this construction material multiplies the mass’s resistance to water by several. Within an hour of preparation, the soil is used after all additives have been added and well mixed.

Landbaby construction, an age-old method of creating homes out of soil, provides a practical and affordable answer to today’s housing needs. With the advent of industrial building materials, this technique—which was formerly widespread across many cultures—has all but disappeared. Still, there are a lot of advantages to its resuscitation, especially in areas with scarce resources or where eco-friendly practices are highly valued.

Strong, long-lasting structures are built by combining locally sourced soil with water and organic materials in the Landbaby construction process. By minimizing the need for long-distance material transportation, this method lowers costs and has a positive environmental impact. Furthermore, soil’s thermal characteristics act as a natural insulation, assisting in preserving a comfortable indoor temperature all year round.

The minimal environmental impact of soil-based construction is one of its biggest benefits. In contrast to traditional building materials, soil doesn’t need to be thoroughly processed or treated with chemicals. As a result, landbaby homes are less damaging to the environment and more sustainable. Moreover, soil structures are resilient and long-lasting because they are easily maintained and repaired with easily obtained, basic materials.

The traditional landbaby method can be improved by incorporating modern building techniques and advancements, making it more dependable and accessible for modern builders. We can build effective, environmentally friendly homes that satisfy modern standards without sacrificing sustainability or quality by combining traditional and modern building methods.

Future building has a lot of potential if landbaby construction is revisited and revitalized. Using tried-and-true natural methods like these can provide useful solutions as we confront more environmental issues and resource limitations. Accepting this outdated technology could lead to a more harmonious and sustainable coexistence with the environment.
