With the onset of autumn rains and melting snow, owners of private houses and garages often face one of the most unpleasant problems - a sharp increase in humidity in the basement. The damp in the cellar It is able to destroy stocks of vegetables, provoke the appearance of mold and, most dangerous for motorists, cause corrosion of the car body if the garage is located above the storage. Fighting moisture is not a one-time action, but a set of measures that require an understanding of the physics of processes and the availability of the right tools.
Before choosing what to dry the room, it is necessary to assess the scale of the disaster and the cause of the water. Often moisture penetrates through microcracks in the foundation or due to poor performance. ventilation. Ignoring the problem can lead to the destruction of concrete and the appearance of a fungus, the spores of which are harmful to health. Therefore, the question of how quickly and efficiently to dry the cellar, is on the agenda of many owners of suburban real estate before each season of planting the harvest.
There are many time-tested methods, from using open fires to modern electric dehumidifiers. The choice of a particular method depends on whether there is electricity in the basement, how large the volume of the room is and how quickly you need to get the result. In this article, we will discuss the most effective options that will help you forget about drops on the ceiling and musty smell.
Preparation of the room and diagnosis of the causes of moisture
The first step to a dry cellar is thorough preparation. You can not just turn on the heater in a room filled with vegetables or old things. It is necessary to completely free up space, take all wooden shelves, drawers and racks outdoors for their separate drying and treatment with an antiseptic. Wooden structures They absorb moisture like a sponge and are an ideal medium for bacteria to multiply.
After the release of space, it is necessary to diagnose the sources of moisture. Inspect the corners, joints of walls and floors, as well as the ceiling. If the water oozes clearly through cracks, no drying will help without prior waterproofing. However, if the humidity is caused by condensation or residues of summer dampness, you can start active actions.
⚠️ Before starting any work, check the serviceability of the ventilation ducts. Often the cause of dampness lies in the clogged exhaust-pipeIt is enough to simply clean with a yarn or metal cable.
It is also important to check the status of the sex. If it is earthy, then moisture can rise from the ground. In such cases, a layer of waterproofing or at least a dense polyethylene film is required before drying. Otherwise, you will heat and dry an endless source of moisture from the soil.
Use of open fire: brazier and bucket with coals
One of the most ancient and effective ways than drying a cellar from dampness is to use heat. The method is based on the creation of a powerful upward flow of warm air, which displaces the moist and warms the walls. For this, most often use a metal brazier, an old bucket or pelvis installed in the center of the room.
In the container put wood, charcoal or briquettes. After the fire starts active air circulation. Warm smoke rises up, capturing water vapor with it, and exits through ventilation. This method requires constant human presence, as it is necessary to throw fuel and monitor safety.
The process can last from several hours to several days, depending on the area of the cellar. It is important to ensure the flow of fresh air, otherwise the fire will go out, and carbon monoxide can become dangerous. The door or hatch must be opened ajar or must be operated. ventilation.
- 🔥 High efficiency due to powerful heat flow.
- 🪵 Fuel availability (wood, coal) in any farm.
- ⚠️ It requires strict compliance with fire safety regulations.
- 💨 At the same time, it disinfects the room, killing mold spores.
After heating the walls and ceiling, the brazier can be removed, but leave the ventilation open for some time to equalize the temperatures. This method is especially good for cellars with earthen floors, as the heat further "seals" the soil.
Candle traction method: safe and effective
If using an open fire in the form of a bonfire in a bucket seems too risky, there is a more gentle option - drying with a conventional paraffin candle. This method is often called "candle traction". It is ideal for small cellars and garage pits where there is no electricity, but you need to remove excess humidity.
The essence of the method is to install a candle under the exhaust ventilation channel. To enhance the effect, the candle is placed at the bottom of the bucket, and a metal pipe is built above it (for example, from an old stove or a drain). Warm air from the flame rushes up the pipe, creating a powerful traction that forcibly pulls moist air from the room.
How long does one candle burn?
One standard candle burns on average 3-5 hours. For continuous operation during the day, you will need to change 5-6 candles, so the method requires control or automatic replacement.
This method is safer, since the flame is isolated, and the risk of ignition of surrounding objects is minimal. However, the speed of dehumidification here is lower than that of the roast. The process can take 2-3 days of continuous work.
To enhance the effect, you can use several candles placed around the perimeter, but always under control. The main advantage is the absence of smoke and soot, if a high-quality paraffin candle without flavors is used.
Use high metal containers (such as cropped cans) to set the candle deeper. This will create a pipe effect and increase traction even without an additional casing.
Electrical methods: heat guns and heaters
The owners of garages and cellars where electricity is supplied were more fortunate. Using electrical appliances is the most controlled way to solve the problem. How to dry the cellar if there is a socket? To help will come heat guns, convectors and special construction hair dryers.
Heat gun. - it's the speed leader. It drives large volumes of air through the heating element, quickly raising the temperature in the room. It is important to direct the air flow not to one point, but to drive it around the perimeter to warm all the walls evenly.
The convector heaters are softer. They heat the air that circulates naturally. This is a longer but energy efficient method that can be left to work for several days without constant supervision if the device is equipped with a thermostat.
| Type of instrument | Drying speed | Energy consumption | Security |
|---|---|---|---|
| Heat gun. | High (clock) | High (2-5 kW) | Medium (hull heating) |
| Convector | Middle (days) | Mean (1-2 kW) | Tall. |
| Oil radiator | Low. | Average. | Tall. |
| Construction hair dryer | Locally high. | High. | Low (requires hands) |
When using electrical appliances, it is extremely important to monitor the state of the wiring. Wet environment and old electricians are a dangerous combination. All connections must be isolated and devices connected through RCD (device of protective shutdown).
Modern solutions: domestic and industrial dehumidifiers
If the issue is edge-on and you need a guaranteed result without constant monitoring, the best solution will be a specialized solution. household dehumidifier. These are devices that drive air through a cooled heat exchanger, condensing moisture into a special tank.
Unlike heaters, dehumidifiers do not heat the air (or heat it slightly), but remove water from it. This avoids air drying and damage to wooden structures that can dry out from the heat.
☑️ Choice of dehumidifier
Modern models are equipped with hygrostats that automatically turn off the device when a given humidity level is reached. This makes the process completely autonomous. You simply place the device in the center of the cellar, set the parameters (usually 40-50%) and walk away.
Industrial adsorption dehumidifiers are able to work even at low temperatures, which is important for unheated cellars in winter. They use special rotors with silica gel, which absorbs moisture and then regenerates by heating. It is expensive but extremely effective equipment for large volumes.
Folk remedies and absorbents: when there is no electricity
In situations where there is no possibility to use fire or electricity, absorbents come to the rescue. These substances are able to absorb moisture from the air, turning into a liquid or changing its structure. How to dry a cellar in such conditions?
The most accessible material is quicklime. It is scattered in boxes and placed in the corners of the cellar. Lime actively absorbs moisture and at the same time disinfects the air, killing mold. For 1 cubic meter of volume, about 2-3 kg of lime is required. After saturation with moisture, it can be used for whitewashing walls or fertilizers.
- 🧂 Salt: Large stone salt tanks work similarly to lime, but more slowly.
- 🪵 Sawdust: The dry layer of sawdust on the floor absorbs moisture, but they need to be changed frequently.
- 📦 Silicagel: Silicagel bags (often found in shoe boxes) can be assembled and used in large cloth bags.
- 🧱 Brick: A hot brick lowered in a bucket gives off heat and dries air (similar to a brazier, but short-term).
⚠️ Note: When working with quick lime, be careful. When in contact with water, it releases heat and can cause a burn. Use gloves and safety glasses.
This method is good as an auxiliary or to maintain dryness in an already dried room. Completely replace active drying with heat or technique absorbents can only in very small and initially dry cellars.
Prevention: How to keep the cellar dry
When you remove the dampness, it is important to make sure that it does not come back. Prevention is always cheaper than repair. First of all, check the pavement around the entrance to the cellar. The rain water should flow away from the entrance, not under it.
Regularly, at least twice a year, conduct inspection of ventilation ducts. Install deflectors on the headers of the pipes, which will increase traction in the wind and protect against precipitation inside the pipe. Also useful are regulatory valves that allow you to change the cross section of the channel depending on the season.
The main reason for the return of dampness is not the removed source of water from the outside (bad runoff, cracks in the foundation). Without waterproofing from the outside, all drying methods inside give only a temporary effect.
For wooden shelves and racks, use antiseptic impregnation. Once a year, take them out in the sun. Ultraviolet perfectly kills fungus spores. If there is an earthen floor in the cellar, consider the possibility of a clay castle or a concrete screed with waterproofing.
Compliance with these simple rules will allow you to keep the microclimate in the cellar optimal for storing the crop and protecting the structures of the garage. A dry cellar is the key to the safety of your car and food for many years to come.
Frequently Asked Questions (FAQ)
How long does it take to dry the roasting room?
The drying time depends on the volume of the room and the degree of humidity. On average, a standard cellar (6-10 m2) requires 10 to 24 hours of continuous burning of coal or firewood. The process is considered complete when the walls and ceiling become warm and dry to the touch, and condensation ceases to form.
Can I dry the cellar with a gas burner?
Use of open gas burners (for example) is extremely dangerous because of the risk of explosion and rapid oxygen burn-out. In addition, the combustion products of the gas can be toxic in a confined space. It is better to use solid fuel in the brazier or electrical appliances.
Will chlorine help to remove dampness?
Chlorine (or chlorine lime solution) does not remove physical moisture, but it effectively kills the mold and fungus that often accompany dampness. Chlorine treatment is carried out after or during drying for disinfection, but not as the main method of water removal.
What to do if the water is on the floor?
If there is water on the floor, it must first be pumped out by a pump or scooped out with buckets. Drying a puddle with heat guns is inefficient and dangerous. After removing the main mass of water, you can start drying air and walls by the methods described above.
