The best way to prevent moisture on the first floor of rural self-built houses

The best way to prevent moisture on the first floor of self-built houses in rural areas, now many people in rural areas choose to build their own houses, which is particularly troublesome for the moisture-proof treatment of the first floor. Every rainy day, the house is always wet. Let's take a look at the best way to prevent moisture on the first floor of rural self-built houses.

The best way to prevent moisture on the first floor of rural self-built houses is 1. First of all, we must understand the reasons for the resurgence of the ground. Indoor moisture regain mainly occurs at the bottom of the house. The main reason is that the moisture in the indoor underground soil layer rises with the increase of temperature. The reason is that the foundation is not well protected from moisture when building a house, so the water in the soil will rush up through the soil layer and form a wet layer on the ground. It must be very uncomfortable to live in such a house.

There are also many methods to solve the indoor moisture-proof problem, but most of them treat the symptoms rather than the root cause. In order to completely avoid the resurgence of the ground, that is, to completely isolate the upward moisture on the ground, it is necessary to add a qualified moisture-proof layer on the ground of the house.

Three methods of self-built moistureproof layer in rural areas

Method 1:

A very common method in rural areas is to flatten and tamp the indoor soil layer in place first, and then spread a thick polyethylene film moisture-proof layer on the soil layer. If possible, it is best to lay another layer of linoleum on the plastic film layer. Then pour 10 cm thick C 15 concrete on the sealing film layer as the base. Finally, the indoor ground layer is made on the concrete base. After this treatment, the water in the indoor underground soil layer is basically isolated.

Method 2:

This method is also very common in rural areas. First, level the ground foundation, compact it with sand, then evenly mix crushed stone and hydrated lime in the middle layer, compact it, and finally wipe the putty slurry with water.

Method 3:

Where the lower part of the wall is in contact with the soil, a horizontal sand layer is built with bricks and stones. Generally, a brick body with a thickness of 20mm is set at -0.06m, and then a horizontal moistureproof layer is made by mixing waterproof mortar according to the ratio of 1:2.

How to prevent moisture on the first floor?

1. Before the moistureproof construction on the first floor, it is necessary to thoroughly clean the ground base to ensure that there are no dirt, dust, sand and other sundries, and then re-build some bricks that can be touched, but it must be kept moist. When the surface of the brick is slightly dry, we can start the construction of the ground moistureproof layer.

2. Stick your feet on both sides of the floor. Generally, cement mortar can be used to smooth the moistureproof layer to ensure the thickness of 2 cm, but the height deviation cannot be adjusted by the thickness.

3, you can use a wooden trowel to smooth the mortar surface, and then wipe it many times when it starts to dry. At the same time, some cement powder can be evenly sprinkled on the surface of the moistureproof layer, which is also convenient for blocking the internal channels of mortar. At the same time, in the construction, try not to leave gaps. If you want to leave a gap under special circumstances, you can only reserve it at the door.

4. After the moistureproof layer on the ground is plastered, it needs to be naturally dried for one day, and then watered and maintained the next day. You can also evenly spread a layer of sand with a thickness of about 2-3 cm on the ground moistureproof layer, cover it with tiles and water it once a day. Doing so can also ensure that the ground is wet enough. Generally speaking, maintenance work takes about three days before other construction steps are carried out.

How to prevent moisture on the first floor?

1. Generally, you can buy some desiccant and activated carbon in shops or supermarkets for moisture-proof treatment on the first floor. It not only has a good adsorption effect on water vapor in indoor air, but also has an obvious removal effect on harmful gases. Of course, you can also use products specially used for moisture protection, such as dehumidifying bags, but the scope of application is limited and only suitable for small spaces or parts.

2. The air dehumidifier on the market also has a good moisture-proof effect, and its working principle is similar to that of a vacuum cleaner. The bottle inside is used to absorb and concentrate the moisture in the air, so as to collect it into water droplets. However, the indoor space is humid in the morning and evening, so it is necessary to close the doors and windows in time to prevent moisture from infiltrating into the room and forming water vapor. When the humidity is low at noon, we can open the window to ventilate and let the indoor air circulate. Of course, air conditioning can also be used to dehumidify, but the effect is slow and it takes more time.

The best way to prevent moisture on the first floor of rural self-built houses II. Causes of moisture-proof on the ground of rural self-built houses

I have seen too many rural self-built houses to prevent the ground from getting wet. There are various methods and waterproof materials used, but the results are not satisfactory. Some of them are better, but others are just better than nothing. What are the reasons for such different effects?

Personally, I think the main reason is not only the method, but also the construction technology. Waterproofing is a comprehensive project, only success and failure, no other possibility, even a little omission will lead to failure. The biggest reason for failure is that the method is wrong, the waterproof layer is damaged, the coverage is not in place, and the lap joint is not sealed.

Several basic methods of moisture-proof on the ground of rural self-built houses.

1, waterproof layer isolation method. This is the most commonly used method to prevent moisture on the ground of rural self-built houses. After the ground is backfilled and leveled, it is paved with plastic film or special waterproof material, and then concrete is poured on the waterproof layer before other decoration. There are many examples of failure of this moisture-proof method, and the specific reasons are those I mentioned above.

In order to ensure effective moistureproof, I think that apart from careful construction to ensure complete coverage, no damage and intact lap sealing, I personally think that the effect of using plastic film as waterproof layer is a bit unsatisfactory, and it is not suitable for waterproof regardless of service life or fragile characteristics. I suggest you choose a special waterproof material.

2. Overhead moisture-proof method. More and more rural self-built houses adopt this moisture-proof method, because many people find that the effect of isolation and moisture-proof is always so difficult to achieve. It is better to make an overhead floor directly to prevent moisture, and the effect is almost 100% reliable.

For self-built houses in rural areas, the moisture-proof of the overhead layer is generally done during backfilling, and the space of about 50 cm below 0,000 is left unfilled, then the precast slab is directly laid on the ground beam as the overhead layer of the ground, and finally several air holes are left on the overhead layer below.

Of course, some rural self-built houses directly build a basement in the lowlands due to their geographical advantages, which can not only increase some available space, but also ensure the moisture-proof effect. Although the cost of this moisture-proof method is relatively high, the effect is not comparable to that of ordinary methods, which is also a fundamental reason why many people adopt it now.

Generally speaking, for all kinds of waterproof materials and moisture-proof practices existing in rural self-built houses, my personal suggestion is that the raised floor has the best moisture-proof effect. If prefabricated panels are used for overhead, it may cost thousands of dollars more, but it can make us sit back and relax, and we will no longer suffer from wet ground.

The best way to prevent moisture on the first floor of rural self-built houses. First of all, the master said: there is no basement on the first floor with heavy moisture, so it is generally not recommended to spread wooden floors. This is mainly because if you don't pay attention to the construction, or the construction technology is not skilled, it is easy to regain moisture or even mildew. It is recommended to choose high-quality tiles. If you decide not to be waterproof, then you must make the indoor floor height higher than the outdoor floor height, and try to lay all ceramic floor tiles on the ground and make beautiful joints. However, it is still recommended that the ground should be moistureproof when building the ground on the first floor. There are three different schemes, namely waterproof mortar moistureproof layer, linoleum moistureproof layer and fine stone concrete moistureproof layer; Just prepare the corresponding materials according to the requirements of building your own house.

Secondly, regarding the moisture-proof measures of the wall, the master said: it is best to coat a layer of waterproof material first, and then add a layer of moisture-proof layer, especially at the junction or corner between the wall and the ground, which also plays a protective role; At the same time, it should be noted that when decorating the first floor, the wall should not be too weak. It is suggested to build another wall to expand the wall area. In addition, for kitchens and bathrooms, the waterproof layer of the wall can be from bottom to top, and the thickness of the protective layer should reach a certain standard to prevent the underground moisture from rising and escaping indoors; At the same time, it is suggested that when buying furniture, it is best to buy feet, because a home with feet will effectively avoid the invasion of moisture on the ground.

Furthermore, Old Master Q said: there is a solution to the resurgence of the house after it is built; First of all, regular cracks should be chiseled into "V" joints, and it is best to seal them with asphalt ointment after cleaning; Or add waterproofing agent 1: 2.5 cement mortar to fill the joint along the mortar joint, but only a slight problem can be solved; If it is a large area of foaming, it must be scraped clean, and then the wall is dry before construction; If wallpaper is used when decorating the wall at home, it is suggested to wipe the wall with a dry cloth first, and then add 4 paper cups of water into the semi-bottle cap of 84 disinfectant to wipe the moldy wall.

However, for friends who like wallpaper in wet areas, it is recommended to decorate the wall with waterproof wallpaper when using wallpaper; In a word, it is very important to build your own house. Of course, when building, we must distinguish between waterproof and moistureproof, and we must never use waterproof methods to deal with moistureproof problems.
