Concreting the floor in the sauna

This is an important stage that ensures durability, humidity control and comfort. Since the sauna is constantly exposed to humidity and temperature fluctuations, it is important to follow several basic principles.
Here are some steps on how to perform concreting the floor in the sauna:

1. Substrate preparation

Insulation: A waterproofing material, such as polyethylene film or a bitumen membrane, must be laid on the prepared primer layer to ensure moisture resistance.
Thermal insulation: Due to high humidity and temperature fluctuations, it is necessary to use thermal insulation so that the floor does not transmit cold and is comfortable to walk barefoot. Most often, polystyrene foam or mineral wool boards are used.

2. Concrete mix

A high-quality concrete mix is ​​required that is resistant to moisture. Most often, concrete of at least C25/30 strength class is used. If you are planning a heated floor, a plasticizer can be added to the concrete mix.

3. Floor slope

It is necessary to form a floor slope in the sauna towards the water drainage point (trap or drainage system). This will help ensure that water does not accumulate and damage the floor or other sauna structures.

4. Heated floors

If you are planning a heated floor, electrical cables or pipes must be laid on the thermal insulation layer before pouring concrete. It is important to pay attention to the recommendations of the heating system manufacturer regarding the thickness of the layers.

5. Reinforcement mesh

To make the floor stronger and more resistant to cracks, it is recommended to add reinforcement mesh to the concrete. This is especially important if the sauna floor will be exposed to heavy loads.

6. Concreting process

When pouring concrete, it is important to ensure its even distribution and compactness. It is advisable to use a vibrating tool to eliminate air cavities and make the floor dense and moisture-resistant.

7. Finishing layer

After the concrete has hardened, the top layer can be installed according to the chosen covering - tiles, stone or wooden flooring. In the sauna area, it is popular to use wooden gratings on a concrete base for aesthetics and a feeling of warmth.

By following these principles, you can be sure that the sauna floor will be moisture-resistant, durable and comfortable.

Pile concreting

Pile concreting provides a strong and stable foundation, especially when it is necessary to build on weak or unstable soil. Here are the main steps and most important aspects when performing pile concreting:
1. Soil analysis and design

Before starting any work, it is necessary to conduct a soil survey and accurately determine what type of piles are needed. These can be:
Bored piles: When piles are formed from drilled cavities into which concrete is poured.
Press-in piles: When piles (steel or concrete) are driven into the ground and then concrete is poured.
Based on soil tests, piles with the appropriate length and diameter are designed.

2. Drilling holes

Holes need to be drilled for bored piles. The choice of drilling equipment depends on the type of soil, the diameter and depth of the piles. It is important to ensure that the drilling work is carried out exactly according to the design requirements.

3. Installation of the reinforcement frame

After the holes are drilled, a reinforcement frame is placed in them, which provides additional strength to the piles. The frame is formed from steel rods, tying them with wire. It must be properly designed so that the piles can withstand the design loads.
The frame must be positioned exactly on the center axis so that the loads are distributed evenly.

4. Concrete pouring

Concrete is poured into the prepared drilled cavities. It is recommended to use high-quality, moisture- and pressure-resistant concrete. Concrete of at least C25/30 or higher class is most often used.
During concreting, it is necessary to ensure that the concrete is evenly distributed and fills all voids. For this, concrete pumps or vibrating tools can be used, which eliminate air voids and improve the structure of the concrete.

5. Waterproofing and protection against groundwater

If the piles will be exposed to groundwater, it is important to use waterproofing materials or add waterproofing additives to the concrete. This will help prevent moisture penetration and protect the piles from corrosive effects in the long run.

6. Pile head formation

After the concrete hardens, the pile heads must be formed. If the piles connect to other structural elements, such as a monolithic slab, the pile heads must be properly formed and connected to the other elements.
