How to build a house from firewood and cement (sauna from logs, logs and concrete)

Although building a home with cement and firewood may seem strange, it’s a novel and practical way to build a sturdy, rustic dwelling. The warmth and charm of a classic log cabin can be achieved by combining concrete with logs, while also utilizing the durability and strength of contemporary materials. This method is particularly well-liked for building warm saunas, where the solid cement structure contrasts with the organic insulation provided by wood.

Choosing the proper firewood and logs is the first step in the process. Hardwoods are generally favored because of their strength and ability to insulate. After obtaining your logs, you must prepare and treat them to withstand the weather and pests. In order to ensure that the structure endures the test of time, cement is used extensively in this construction method to fill in gaps and reinforce the structure.

Using this method to build a house or sauna requires careful planning and execution. To build a tight, insulated structure, you’ll need to know how to mix and apply the cement correctly in addition to knowing how to stack and seal the logs. The strength of cement and the organic beauty of wood can be combined to create a home that is both aesthetically pleasing and functional with the correct materials and construction methods.

Step Description
1. Gather Materials Collect firewood, cement, sand, gravel, and water. Ensure you have enough materials for the entire project.
2. Prepare the Foundation Clear the building site, dig trenches for the foundation, and pour a concrete base. Allow it to cure properly.
3. Lay the First Layer Place a layer of cement mortar on the foundation. Arrange firewood logs horizontally in the mortar, leaving small gaps between them.
4. Fill the Gaps Mix cement, sand, and gravel to create concrete. Fill the gaps between the logs with the concrete mixture, ensuring it"s packed tightly.
5. Continue Layering Repeat the process: apply mortar, place logs, and fill gaps with concrete until the walls reach the desired height.
6. Reinforce the Structure Insert metal rods or rebar vertically through the walls at regular intervals to add stability and strength.
7. Build the Roof Construct a wooden or concrete roof framework. Cover it with suitable roofing material, ensuring it"s well-insulated.
8. Finish the Interior Install windows, doors, and insulation. Apply a finishing layer of cement or plaster on the interior walls for a smooth surface.
9. Add Final Touches Paint or decorate the exterior and interior as desired. Ensure proper ventilation and moisture control for durability.

DIY house

60 cubic meters of firewood can be used to build an 80 square meter log home. Any kind of wood will work, but hard, premium drying varieties are preferable. Typically, they receive chopped firewood; however, it is preferable to avoid using round logs because they have a tendency to split along the fibers when drying.

  • Before plastering, the erected walls last about 2 months, sometimes the craftsmen say to wait a year – only after that insert doors, windows, carry out finishing work.
  • To avoid mistakes during the construction process, experts advise first practicing on smaller buildings – this could be a bathhouse, a barn.
  • To better retain heat, a thin layer of mortar for a firewood house is applied only to the edges of the logs, and inside the resulting space is filled with a mixture of resin and sawdust.
  • To obtain logs of identical length, a sawhorse is often used – the trunk is pressed against the support at one end, and the chainsaw bar is pressed tightly against the stop in the cutting area.
  • The corners of the house are tied with timber, which is placed at a certain pitch.
  • If you plan to plaster the facade of the house or the craftsman is unable to create a flat vertical surface, the use of panel masonry is allowed: a plywood panel or boards are mounted on one side of the wall, each log is placed tightly to the panel, after a day the limiter is mounted further.

Building a home out of cement and firewood blends traditional craftsmanship with contemporary materials to produce a distinctive and long-lasting building, which is why it’s frequently used to build saunas out of logs. By utilizing the strength of cement and the inherent insulating qualities of wood, this technique creates a warm and durable home. Carefully stacking the logs, caulking gaps, and making sure there is enough insulation and ventilation are all part of the process. Through the combination of these materials, homeowners can take advantage of concrete’s longevity and low upkeep while still creating a rustic look.

Masonry mortar

Using cement and firewood, a standard building solution is made.

  • 9 parts of washed sand
  • 3 parts of wet wood sawdust
  • 2 parts of the cement
  • 3 parts of lime

After thoroughly mixing all the dry ingredients, water is added little by little until the mixture becomes hard and semi-dry (it should contain less plastic than the mixture used for bricklaying).

Examine this method: roll a small, dense ball out of the solution in your hands, toss it into the air, and catch it with your palm; do not paint or flatten it.

They placed firewood on a clay solution, but a more contemporary solution would be to go with a light, warm pantry made of cement (the right brand of cement is required for buildings with the chosen number of stories). Concrete is better and more effective, despite being more costly.

Building lime and sawdust (prepared as 1 part lime and 12 parts sawdust) are sealed in the middle of the wall (the space between the logs) for insulation purposes, shielding the structure from fungi, insects, and mold.

Preparing logs for laying walls

Use split, sawn, or round wood for wall installation. The ideal split logs are those that have already dried thoroughly. Additionally, avoid haphazardly combining logs of various shapes and grades within the same construction.

Round or split wood is already prepared and cut into pieces along a length equal to the building’s thickness (between 20 and 60 centimeters), after the bark is peeled off in its raw form (this method is easier). Bark-peeled logs are dried in woodpiles under a canopy, with all ends left exposed to the elements. The logs must be dried for a minimum of a year if they were taken from the forest (i.e., if their moisture content is the same as it is naturally).

The logs may split during the drying process, usually experiencing a reduction in size. The logs need to be split based on the visible through cracks.

Using firewood and cement to build a home is an inventive and useful way to combine natural materials with contemporary building methods. With cement and logs or firewood, you can create a strong, sturdy, and rustic structure that is notable for its longevity and distinctive appearance. By using locally sourced materials, this method not only provides an affordable building solution but also encourages sustainability.

Logs or firewood are arranged in a formwork and the spaces are filled in with cement. Excellent thermal mass is provided by this mixture, which helps to control indoor temperature and increase energy efficiency. As a result, there is less need for artificial heating and cooling systems because the house stays warm in the winter and cool in the summer.

Its versatility is one of the most attractive features of this construction method. A full-sized house, a cozy sauna, or an addition to your current residence can all be built with logs and cement, which can be tailored to suit a variety of architectural tastes and aesthetics. A visually pleasing and well-balanced design is produced by the natural texture and appearance of the wood contrasted with the smooth, solid appearance of the cement.

Moreover, a lot of do-it-yourselfers can master this building technique. You could save money on labor costs by doing this project yourself if you have the necessary tools and basic knowledge. It’s a fulfilling experience that gives you the satisfaction of making something with your own hands in addition to a distinctive living area.

To sum up, building a home out of cement and firewood provides a unique combination of energy efficiency, longevity, and rustic charm. It’s a naturally occurring building option that can be tailored to meet different needs and preferences. This approach offers a creative way to create a unique and useful home, whether for a main house, a sauna, or an extra building.
