How to solve the problem of water on the cement floor? What should I do if water seeps up the cement floor?

One word - plugging, plugging the small voids of the cement structure, so that water vapor cannot spill into the ground. To achieve this, we can use concrete sealing curing agents, which are often used in floor construction.

The concrete sealing curing agent material can effectively penetrate into the concrete for 5-8mm, and chemically react with a large amount of hydrated unfinished calcium and magnesium ions to form silica sol, and then seal the hardened concrete structure, and continuously increase the hardness and wear resistance of the concrete. After treatment, the ground can form a solid as steel and bright as a mirror.

The construction effect of Yigute concrete sealing curing agent.

In practice, concrete sealant curing agents are often used to deal with the dampness of warehouse floors. When we find that the cardboard boxes in the warehouse are wetted by water vapor escaping from the ground, we can treat the floor with a concrete sealing curing agent to block the infiltration/escape of liquids. The hardening effect of concrete sealing and curing agent can also physically strengthen the cement floor, thereby reducing the trouble of sand and dust.

This is the solution to the problem of water seepage on the concrete floor.

The concrete floor of a rural house is relatively wet, which means that you did not raise the foundation of the house when you built the house, causing the moisture below to upload up. If you choose to rectify now, you can apply a layer of waterproofing on the concrete floor, including the wall one meter high, and then re-lay a layer of cement mortar.

The return of moisture is due to the relatively high temperature and humid air, that is, when the relative humidity reaches more than 90%.When the air is pregnant with almost visible water vapor everywhere, it is easy to sink, and after sinking, it is easy to adsorb on the cement floor and condense into small water droplets, which will increase more and more after a period of accumulation, thus forming a large-scale damp situation.

On the cement floor in the living room of some old houses, the overall cement floor becomes somewhat dense and becomes uncompact, so that the cement of the soil base layer begins to rise and penetrate upwards through the holes in the cement, and eventually causes the floor material to become damp, with the change of humidity that occurs in the whole room.

The solution is also very simple, the first is to close the doors and windows on rainy days, so that the outdoor moisture can be blocked to a certain extent, and the second is to paint the ground through cement.

Precautions

The air conditioner has the effect of cooling and dehumidifying, and if the air outlet is always blowing in one place, it is easy to cause shrinkage joints in the floor there. Therefore, when using an air conditioner in summer, it is best to let the air outlet swing up, and do not blow in one direction. In addition, the entrance is also a tuyere, which is very dry.

Experienced installers will seal wax at the closure so that the moisture in the board does not escape.

Owners can also wipe these floors with a damp cloth to avoid over-drying. It is quite wrong to live for a long time after the renovation, not to ventilate, or to put newspapers, plastic paper, etc. on the floor to prevent dust, etc. Due to the lack of ventilation for a long time, in a closed environment, the floor is prone to deformation and shrinkage joints.

It's best to replace it with hardwood flooring, but it can be a bit expensive.

Isn't it on the first floor, if it's the first floor, it's only paved with floor tiles.

Water on the ground depends on the situation:

If it is upstairs on the ground, the air humidity is high, and the water vapor in the air liquefies and turns into water droplets that condense on the ground, that is, the moisture returns.

If it is the ground floor on the first floor, in addition to the above reasons, there may be another reason: that is, the water table is high, and the underground moisture rises to form water droplets on the ground.

Solution: Moisture insulation on the ground, air dehumidification, and enhanced ventilation.

It is recommended to pave the ground to rotate, and the ground will not seep water upwards.

Summary. Pay attention to moisture drainage.

Cement floor dampness occurs mostly in the rainy season, the rain in the south is more, and the temperature is high, which will cause the indoor humidity to be particularly large, and will produce condensation on the surface, and the smoother the ground, the easier it is to return to moisture, to do a good job of indoor moisture removal, exhaust fans, desiccant, etc. can be used, but this kind of weather is not suitable for opening windows, unless it is sunny and the sun is big.

After many years of house, the cement floor on the first floor is always wet, is there any way to solve it?

Cement floor damp can be paved with self-leveling, it belongs to the thick paste epoxy floor coating, can avoid the wet problem of cement floor to a certain extent, or paint on the ground, not enough to choose compressive strength, hardness, strong acid and alkali resistance, wear resistance, pressure resistance, waterproof performance and other good paint, not only can make the cement floor avoid moisture problems, but also better decoration.

Note that the moisture drainage cement floor is mostly in the rainy season, the rain in the south is more, and the temperature is high, which will cause the indoor humidity to be particularly large, and will produce condensation on the surface, and the smoother the ground, the easier it is to return to moisture, to do a good job of indoor moisture drainage, exhaust fans, desiccant, etc. can be used, but this kind of weather is not suitable for opening windows, unless it is sunny and the sun is big.

Here's how:

After the cracks and hollows are partially treated, the surface layer should be fully moisture-proof and sealed. The principle of treatment is to block the capillary seepage channel in cement mortar or concrete. Generally, the method of applying waterproof paint or waterproofing agent can be used.

1. Before painting, chisel the surface layer, clean it, and apply two waterproof coatings. The first application is applied so that it penetrates deep into the pores. After the first coating is dry (generally about 24 hours), it will be applied a second time to form an overall waterproof coating film.

At the corner of the floor and the wall, the paint should be brushed to the height of the wall baseboard.

2. After the original ground is treated with moisture, a new surface layer is made. The selection of new surface materials should consider the selection of high strength, wear resistance, certain moisture-proof ability, easy to clean, practical and beautiful ground materials, and cement mortar surface layer can also be used. In general, it is not advisable to open the windward window, and the windward door should be opened less to reduce the influx of humid air into the room.

This is a phenomenon of "resurgence", which is actually a natural phenomenon that often occurs during the transition period from winter to spring. The main reason is the difference between indoor and outdoor temperatures. Due to the frequent cold air activity after winter, the temperature is relatively low due to the influence of the cold air mass, and the indoor temperature is also decreasing day by day; After the beginning of spring, the outside world heats up faster than the indoors, and relatively speaking, the indoor is a cold source.

At this time, the warm and humid air mass in the south is more active, the warm and humid air mass contains abundant water vapor, when the hot and humid air flow surges northward, that is, people often say "south wind day", blowing into the room, encountering colder ground and walls, furniture and other utensils, its water vapor will condense into small water droplets, and even form a flowing water layer, that is, the so-called "resurgence", also called "reflux".

In particular, the tiled floor, wall, painted furniture surface, mercury mirror, aluminum alloy doors and windows and other hard utensils are not breathable, and the water vapor is not easy to absorb or penetrate, and the phenomenon of "resurgence" is even heavier. In general, there will be several "resurgence" weather processes at the turn of winter and spring in the Jiangnan area. "Re-tide" is also called "back to the south".

This complex phenomenon is mainly caused by the origin.

The reason is that the place where you live belongs to the wet land, in a cloudy day, the ground seeps out of the water droplets, in fact, it is not the ground seepage, the air is more humid on a cloudy day, the temperature becomes lower, and the ground ground (soil) temperature is higher than the air temperature, as soon as the moisture in the air touches the ground, water droplets will be formed, resulting in water seepage on the floor!

In summer, on the contrary, the floor (soil) and the air are exposed to the sun at the same time, and at noon, the temperature difference is not large, but when the fan is turned on, the ground temperature is greater than the air temperature, so that the water in the surface evaporates out, and the floor on the air contact surface cools to form water droplets.

The above surface can form water droplets for the following reasons:

1. The humidity of air and surface (soil) is high.

2. There is a temperature difference between the air and the surface (soil).

The solution can be:

1. If conditions permit, build a basement, so that the basement is more humid, and the surface above the basement is relatively dry.

2. Use the soil method to operate, lay dry items under the floor, such as limestone, or rural straw will be laid!

It's not difficult to solve the problem of too wet concrete floor like yours, if the conditions allow, you can build a basement so that the moisture will not return. Or if you put something dry under the floor, such as limestone or ash from rural straw, the resurgence of moisture will also be suppressed.

You can ventilate, or paint damtite moisture-resistant paint.
