creation methods, options (photos and videos)

How to make a rough floor in a wooden house? To implement this venture, you must first understand what it is and what methods of creating such coatings exist at the present time. Such floors in a wooden building imply three terms:

1. A smooth base on which laminate, parquet or linoleum is laid. It is usually made of sheets of plywood or chipboard. Perhaps the use of boards that fit on the logs.
2. The first (lower) layer of a double plank floor in a wooden house, which is used when lags and floor beams are located relatively rarely. In this case, the boards included in the subfloor are usually laid diagonally, which gives it increased strength.
3. The bottom layer of double coating, which has a special insulation and is equipped with waterproofing.

How does a rough floor work?

A floor in a wooden house usually consists of two bases. The one that is under the top layer is considered rough. The evenness of the upper part depends on its condition, so a simple alignment of the floor will not give the desired result. To create a durable coating, you must perform certain actions so that the subfloor does not break or crack. New technological solutions make it possible to do it better.

Special mixes are used for this, but this does not mean that conventional cement-sand screeds can be neglected.

The floor in a wooden house provides strength and evenness of the main coating and consists of such elements as:

• screed - it is made to level the base and disguise various communications;
• a waterproofing layer - its function is to eliminate the possibility of water penetration;
• underlying layer - to create a uniform load;
• interlayer - for communication between floors;
• thermal and sound insulation - improves floor performance.

The floor in a wooden house and its varieties

This coating can be made in the following ways:

• logs are used;
• applied the so-called adjustable floor;
• a screed is made (dry and wet type);
• pour a bulk coating;

Consider all these methods for creating a subfloor in a wooden house.

The most ancient and well-tested technology is the device of the base on the logs, which are made of wood or plastic (parallel bars). They are laid strictly horizontally. Such a floor on logs is usually done in a wooden house, as it provides good ventilation and allows hiding communications in the voids between the bases. The air gap does not allow the tree to rot, and if you put sound and thermal insulation between the floors, it will improve comfort.

To properly set up the subfloor on the logs, the following conditions must be met:

• between adjacent bars observe a step of 35-45 cm;
• strictly horizontal arrangement The lag should provide a zero slope;
• , walls should be left with gaps of 2.5-3.5 cm, which are then covered with a plinth;
• a crate of plywood or chipboard is installed on top of the logs;
• of all the laying options that are used in a wooden house, the best one is in pursuit;
• the edges of the plywood sheets are installed with a gap of 2-3 mm, i.e. the edges are next to each other plates of material must be in one lag, which will allow to get rid of squeaking;
• if the thickness of the sheets of plywood or particleboard is not enough, then another layer must be laid; lags.

Adjustable floor in a wooden house

If you need to raise the base level by 3-10 cm, then use this relatively new method of laying a subfloor. For this option do a fairly simple installation. Under such a floor, various communications are carried out and heat and sound insulation is installed. How is this type of base made?

They drill holes in plywood and insert plastic sleeves with internal threads into them. With the help of bolts-racks lags are fastened with dowels on the concrete. Sheets of plywood with sleeves are put on these elements. The screws themselves can rotate, with the base plates being lowered or raised. This makes it possible to level the surface of the floor in a wooden house.

Using the screed

This is the most popular option. It can be made by wet or dry technology. The second option is the so-called backfill floor, which contains several layers. How do they do it?

The insulation is laid on the base, which does not allow steam and moisture to pass through, for example, a plastic film. It is secured with adhesive tape.A dry backfill is applied on top of it, which is evenly distributed over the entire area. Usually used claydite, slag or perlite sand. Along the walls (around the perimeter of the room) lay elastic material, which is needed to compensate for the thermal expansion of the floor. After that, you can make the main flooring, which consists of sheets of plywood, connected in modules with polystyrene foam, or other materials (chipboard, OSB). They are set in 2 layers, which are sealed with glue or screws. This is done with the mandatory displacement of the joints. Then the entire structure is coated with an anti-fire compound. Mounted above the finish base.

If a regular concrete screed is made, the floor in a wooden house can be made independently. The technology of this process is as follows:

• the base is cleaned of dust and debris;
• tamping is done;
• the underlying layer is laid up to ten centimeters thick and compact it. For this, crushed stone is used;
• the same process is carried out with sand (layer height 9-12 cm);
• to protect against dampness, heat and waterproofing is applied;
• is applied gypsum or cement-sand mortar;
• the obtained subfloor is evenly matched.

Allow the screed to dry. This can last 7-30 days - it all depends on the thickness of the solution. This type of screed allows leveling differences in heights of up to three centimeters and obtaining a flat surface on which you can lay laminate or parquet, but at the same time you need to apply a finishing covering.

Self-leveling coating in a wooden house

This is the most modern technology for creating a foundation for the floor. It combines the creation of a rough and finish coating. A self-leveling floor is made of a mixture of cement and synthetic resins, which is reinforced with elements that do not give rise to cracks.

The process itself consists of pouring the base with this mixture, to which leveling a needle roller is used. He needs to remove air. The polymer rough floor is much thinner than concrete, therefore it dries faster (no more than 15 days).

Creating an intermediate layer

Any floor cannot do without a substrate, which can be strengthened on the draft floor by such methods:

1. To fix the polyethylene, you can use double-sided tape.
2. With glue. This is the most common option, but you need to think carefully about the installation, otherwise if an error occurs, the underlying layer cannot be removed.
3. To create a very strong underlying base, use an iron for welding and the so-called thermal scraper.
4. The fastest method is to use screws and brackets. But this technology requires skills. Staples must be attached so that they do not stick out at the place of fasteners. At the same time, they should not deform the base, and for this they should be buried to a low height.

Required materials, tools and accessories:

1. Wooden bars.
2. Plywood sheets or chipboard.
3. Cement mortar.
4. Heat and waterproofing.
5. Bulk mix.
6. Plastic bushings.
7. Pillar bolts and screws.
8. Rule and needle roller.
9. Rammer.
10. Glue.
11. Staples.
12. Hammer and nails.
13. Tape measure.

You can make the floor subject to the entire process chain and follow all the tips listed above.

Only then will this floor in a wooden house last for many years.
