The importance of basement waterproofing
The most dangerous seasons in terms of groundwater penetration into basements are autumn and spring. It is during these periods that the greatest amount of precipitation falls, which is why the level of groundwater is extremely unstable.
Basement waterproofing.
Basement insulation should begin with a cause analysis. It is necessary to find out what is the weak link in the process of protecting the basement from groundwater. There may be several options: skipping the stage of waterproofing work, poor-quality basement insulation, use of unsuitable waterproofing agents or their improper use, breakage of the pipeline.
In general, if the basement is flooded, it loses its purpose (becomes dangerous for storing food and being in it for a person), the property of isolating water in the basement for other rooms in the house is lost. There is always high humidity and condensation. And this further leads to the appearance of various fungi, including mold. Basement insulation needed.
By all means, all the basements of the house are located either above or below the groundwater mark. And in order to carry out appropriate work to eliminate leaks and avoid them in the future, it is necessary to be based on this level.
Liquid rubber is a new method of protecting the premises from flooding
Construction technologies do not stand still, but are constantly being improved. Liquid rubber is considered an excellent way to protect a house from a flood in the basement. This is a new method of external waterproofing that requires special attention.
Liquid rubber consists of an elastomeric aqueous emulsion. Sprayed on the surface, it instantly forms a membrane on the walls, floor and thereby prevents water from entering the basement.
The material has several advantages:
- Compatible with all kinds of surfaces;
- Full tightness due to the absence of seams;
- The membrane is resistant to water, earth gases and ultraviolet rays;
- Prevents condensation in the room;
- Insensitive to temperature changes;
- The service life reaches 50 years.
Liquid rubber differs from other means of waterproofing in its low weight.
Before applying a waterproofing layer to the foundation walls, clean and dry the surface.
If groundwater is at a high level, then additional protection is created for the waterproofing layer in the form of a brick wall or profile membranes.
Such a precautionary measure will completely eliminate the possibility of interaction between groundwater and waterproofing agent.
How to choose
A well-functioning electric water pump is the basis of drainage structures. The quality of removal of excess moisture depends on how correctly and correctly it works.
There are a number of criteria that you need to pay attention to when choosing this device.
First of all, the design should have a metal (cast iron) block-case.
It is also necessary to be able to pump out dirty water with rigid connections measuring 10–12 mm.
And it is also important that the pump has an automatic float switch, which is very unpretentious and simple from a technical point of view.
The pump is located in the middle of a plastic moisture trap that filters and collects water. A similar perforated container is installed in the filler layer. Water enters the water collector from the internal contour of the drainage structures through its side wall. The container must have an airtight lid: it will prevent the evaporation of moisture that can enter the basement, and also protect the water collector from getting various objects that can upset the operation of the switch.
But it is very dangerous - to trust the dryness of the basement only to the pump.In the conditions of a de-energized building due to a storm, the cellar will quickly fill with water. In order to insure, the structure is equipped with a spare battery-powered pump, mounted in the same water collector where the main pump is located. The discharge air duct for it can be used the same.
Very efficient systems use pumps that are equipped with accumulators and filling devices for long-term additional use.
The charger is extremely important, as untimely recharging can lead to basement flooding
The pumped water, as a rule, is fed through the pipeline to the drain, if any, or taken out as far as possible from the building. It is necessary to install the discharge air duct in such a way that it is not subjected to freezing in any way in winter.
Our recommendations will help you fix the leak and remove the remaining water.
How to make a dry cellar, see the following video.
Sealing the foundation walls of the zero level
By impregnating the soil near the base of the house, the water forms a hydrostatic effect, rushing it through all the damage and joints of the base of the house. Coating insulation will be the first protective feature.
Among the compositions specialized for this action, the most popular are materials containing bitumen, applied externally to the base of the house. Bitumen reduces the porosity of concrete, but later loses its flexibility and becomes more fragile, which leads to cracks. A variety of plasticizers improve the situation, but their protection will be short-lived.
Expanded polystyrene is effective in order to preserve the integrity of the coating when backfilling the base of the house. This material is stable, highly durable, and resistant to bacteria living in the soil. Expanded polystyrene tiles contribute to the thermal break between the base of the house (foundation) and the soil being filled. Despite this, manufacturers claim that the current highly flexible coatings do not need any protection, but one should not reject another insulation for foundation walls in a residential building.
Before applying the coating to the concrete, the plane must be cleaned
In addition, it is necessary to correctly establish the height of the ground level after the completion of earthworks, and this factor should be taken into account when applying the coating. An incorrectly determined level will lead to the fact that under the backfill there will be a part of the wall without proper (or without any) waterproofing
Inevitable cracks from shrinkage in the foundation will eventually lead to leaks and shrinkage, so you need to process the entire foundation with a margin.
A replacement for a moisture-proof coating will be geocomposite (draining base, special filter and diaphragms) drainage mats attached to the walls of the base of the house.
The problem of using similar polymeric materials is corresponding: in the absence of effective drainage of the soil at the base of the house, water hydrostatic pressure will push water up between the walls and mats. With this option, water will penetrate through various cracks in the foundation wall.
Causes of stink from the basement
Unpleasant odors occur in the basements of both old apartment buildings and new ones. If in old buildings the wear of ancient pipes becomes the cause, then in newly erected buildings leakage may occur due to improper installation of the sewer system.
At first, it stinks only in the technical room, but the "aroma" quickly penetrates into the entrance, and from there - into the apartments of the lower floors.
Leaks can be emergency, but in buildings that have been in operation for more than a dozen years, pipes can have small gaps and stink for a long time. As a result, the apartment smells like sewage all the time, which is unsafe for health.
A terrible smell penetrates up the ventilation pipes, it is felt on the landing, in the dwellings. The air in the basement is warm, so it rises easily.
The main reasons are:
- A break in the integrity of the pipes of the sewer system, as a result of which all drains accumulate on the basement floor.
- Perhaps water has leaked from the plumbing, it creates an excess of moisture in the basement, leads to the appearance of fungus, smelly mold.
- The basement is flooded with groundwater. This often happens after heavy rain or sudden snowmelt. If there are no drains or drainage on the technical floor, then the groundwater will stagnate, also causing a deterioration in air quality.
- The problem with the smell can be caused by the fact that a lot of biological material has accumulated in the lowest room (corpses of homeless animals, rodents, their excrement). There should be a person responsible for the cleanliness of this area, he will immediately remove foreign objects.
- Dampness in the lower tier of an apartment building also appears when the craftsmen drain the water from the heating system. Work can be carried out incorrectly, with leaks, with stagnation of puddles in the basement.
Residents of high-rise buildings are increasingly redevelopment of their apartments, changing the location of plumbing. Naturally, the position of pipes of engineering systems also changes.
If the installation according to the new water supply or sewerage plan was not done correctly, stagnation is possible in the racks, sewer wells, causing a terrible stench.
Any work related to the repair work must be carried out by professionals and with the permission of the relevant authorities.
How to avoid
It’s not worth skimping at all - it’s easier (and often much more economical) to build a good cellar on the first try than to modify and redo it endlessly. For this reason, at the same time, it is necessary to thoroughly seal the walls of the base of the house and remove water from it in a timely manner. If the water nevertheless made its way into the cellar, try to get rid of it as soon as possible in order to save the basement from excess moisture.
A far-sighted owner, already during the construction of the building, will definitely take care of the expedient organization of the drainage structure and the impeccable waterproofing of the basement rooms. A drainage system will undoubtedly help waste moisture to drain deep into the soil and not have any contact with the cellar, and moisture in the basement will by no means be a significant problem.
According to the perimeter of the basement of a previously built building, it is allowed to make drainage channels. And, if there is a chance, fix them from the inside of the basement. In order to do this, as a rule, false parquet is used.
If the cellar is flooded or only floods, it is urgent to deal with the problem. If it floods from groundwater, then they need to be diverted and the structure drained, and in this way you can protect the cellar.
internal drainage
Internal drainage is a worse option, which does not allow moisture to rise above a certain level and is carried out along with the installation of the base.
Drainage channels are laid in the floor of the base, increasing its thickness, while they are equipped in the same way as in the first case, observing the drainage layers and arranging the drive.
If the flood waters rise too high on the site, then a combination of two methods at once will be the best choice.
External drainage will drain water under normal conditions, and internal will save if the situation gets out of control during a flood.
In order for water to better leave the groundwater storage tank, you can install a pump in it with an automatic float sensor that diverts water into the sewer or outside the site.
Sanitation of the basement after the breakthrough of the sewer house
This organization also accepts written complaints and registers them. ATTENTION! Lawyers recommend making an individual complaint, it will be considered faster. Collective appeals require a longer consideration
A written appeal about a sewer problem should be written in business language, with an accurate indication of all the facts. The address, the time of appearance of the stench, and other data are indicated.
The complaint indicates where the appeal has already been sent, which company has not responded to the information.
Solving the problem taking into account the law Each apartment building has a management company that must control the technical condition of all its systems
ATTENTION! According to the housing legislation, the Criminal Code ensures the comfort and safety of residents in a multi-storey building
Attention
But if in a private house the presence of a cellar is a matter of personal preference, then multi-storey buildings, without exception, are built with a basement, which may not be used at all. In any case, periodic disinfection of the basements of residential buildings is required.
Why disinfection is needed It may seem that the disinfection of the basement is something invented, because no one has done it before.
This statement is not true, because our grandparents regularly whitewashed the cellar, but they did it not for aesthetic reasons, but in order to disinfect.
Basement disinfection
Important
Outside and inside, the house can be very beautiful, but not everyone dares to look behind the door leading down, as the picture there is extremely unsightly, and if you imagine that your beloved cat will come out of the basement of a multi-storey building through this door, it will somehow become uncomfortable. yourself.
Even if a domestic cat does not climb basements because the owner leads her on a leash, it cannot be guaranteed that there will be no contact with a stray cat, and that the family pet will not bring an unpleasant surprise to the apartment. The scale of the problem due to the appearance of fleas is underestimated by many, since they consider several bites to be a simple nuisance, because you can get rid of these insects by acquiring poison.
Where to go for an unpleasant smell from the basement
The court must also take into account the degree of physical and mental suffering associated with the individual characteristics of the person harmed.
According to Art. 1101 of the Civil Code of the Russian Federation compensation for moral damage is carried out in cash.
The amount of compensation for moral damage is determined by the court, depending on the nature of the physical and moral suffering caused to the victim, as well as the degree of guilt of the tortfeasor in cases where guilt is the basis for compensation for harm.
When determining the amount of compensation for harm, the requirements of reasonableness and fairness must be taken into account.
The nature of physical and moral suffering is assessed by the court, taking into account the actual circumstances under which the moral harm was inflicted, and the individual characteristics of the victim. According to Art.
www.santechniki.com
Disinfection of the basement of an apartment building It is not only the basements of private houses that need care, but also apartment buildings.
Next, we will consider in which cases disinfection of the basement of an apartment building is required.
Protection from parasites Many residents of apartment buildings do not think about anything other than their apartment.
On the one hand, it seems so, but if the inhabitants of the house do not care about the basement, then people often visit it, and very often they use the services of "carriers" - cats and dogs. We are talking about fleas, lice, bedbugs, ticks and other living creatures that are unpleasant and harmful to humans.
Therefore, disinfection of the basement should be carried out regularly.
What to do with a sewer break in the basement?
In this connection, his demands for imposing on the defendant the obligation to drain the basement of an apartment building, clean the basement from debris, disinfect, deratize, and ensure the proper sanitary condition of the basement are subject to satisfaction. According to Art.151 of the Civil Code of the Russian Federation, if a citizen has suffered moral harm (physical or moral suffering) by actions that violate his personal non-property rights or encroach on other non-material benefits belonging to the citizen, as well as in other cases provided for by law, the court may impose on the violator the obligation of monetary compensation for the specified harm
When determining the amount of compensation for non-pecuniary damage, the court takes into account the degree of guilt of the offender and other noteworthy circumstances
Waterproofing the floor and walls in the basement of the house
To prevent water from penetrating into the premises, they organize an additional level of protection - waterproofing. According to statistics, compositions with penetrating actions are in demand.
Basement waterproofing scheme
Penetrating into the structure of concrete, they come into contact with moisture and cause the formation of crystals that fill all the flaws.
If you smear the walls in the basement with this tool, then they will withstand the influence of water pressure weighing up to 13 kg per square centimeter.
As an alternative for internal waterproofing, polymer-cement compositions are used. Their disadvantage is susceptibility to sudden changes in temperature.
Drainage organization
In addition, the problem of water in the basement will help to solve a competent drainage system. To divert water from the gutters away from the building - such a decision may seem true at first glance. However, not all buildings have effective rainwater drainage. Another method to divert rainwater is to combine drainpipes with a multi-outlet, which has a strong slope from the building.
Due to the accumulation of debris in the gutters, the diameter of the drain pipes must contribute to the reliable removal of moisture, including during a downpour - no less than 100 mm. In this case, the best outlet tube for the design is 150 mm.
All sorts of twists and turns are not welcome in the gutter channel, as they will certainly become clogged with a variety of debris and other elements of life. If the length of the gutter is more than 5 m, then several outlet channels should be considered.
Internal drainage system
Before making internal flood protection, keep in mind that you will have to sacrifice free space by raising the floor level. Since the pipes are recommended not to be laid underground, but on top of the old floor.
Getting started, arm yourself with construction tools, materials: shovels, buckets, crushed stone, sand, pipes, a drainage well.
Laying drainage in the basement of a house or cellar consists of the following steps:
- Consider a drainage scheme. If the room is not more than 20 square meters, then the pipes are laid along the walls. In the basement of a larger area, you will need to make a whole network of pipes. The minimum distance between them is 3 meters. At the same time, pipes are installed at an angle in the direction where the drainage well will be located.
- Fill the floor with fine gravel, expanded clay or coarse sand and level the drainage layer so that a slope of 20 mm is formed for each meter of length.
- Take the geotextile and lay out the material sheets, observing the overlap size - 15 cm;
- Start laying pipes according to the scheme drawn up in advance;
- Check if their slope is observed;
- Wrap drains with geofabric;
- Install a draft floor.
If there is no desire to make the height of the room less, then install the drainage pipes under the floor. In this case, use only perforated plastic drains with a diameter of at least 8 cm.
As for the drainage well, it can be made from a pipe with a radius of 10 cm or built from concrete.
The drainage well is installed so that the bottom is at a depth of 50 cm from the level of the drain. It is recommended to install a plastic container at the bottom, which acts as a filter and collects dirt.
Causes of water in the basement of the house or cellar
Flooding of the basement of a building or a detached cellar occurs as a result of:
- lack of drainage;
- improperly equipped drainage system;
- clogging of the drainage system with debris;
- violations of the waterproofing layer of walls and floors;
- changes in the hydrogeological situation, the cause of which was the movement of the internal layers of the earth;
- abundant seasonal rainfall.
The problem cannot be ignored, since water has a detrimental effect on the construction of a wooden and brick house. What to do? First of all, pump it out with a hose and a pump, and then dry the room.
But the solution to the problem does not end there. Measures should be taken to prevent water from accumulating in the basement or cellar in the future. This requires doing internal and external drainage, waterproofing the foundation, floor and walls.
Which material to choose
If the gardener nevertheless decided to build a cellar on a site with a close occurrence of groundwater. He needs to remember that from moisture one way or another, all materials are destroyed faster, just some more and others less.
In no case should wood or brick be used for construction, as the wood will rot instantly and will not hold back moisture from penetrating inside.
And the brick, despite the apparent strength, is very easy to crumble and collapse from moisture, and because of the porous structure it allows moisture to pass through. The option of building an earthen cellar, for obvious reasons, should not even be considered.
It is better to use modern materials specially designed for such cases, for example, waterproof brands of cement that can harden even under water.
Such cement will cost twice as much and will probably have to be ordered, but it will make it possible to simplify construction and extend operation as much as possible, but simple cement or concrete blocks will also work, although they will collapse over time.
Stone is the strongest material, but its use is not considered, since few people can find so many natural stones of the desired shape and size near their site, and the construction of walls from it itself requires certain building skills.
External waterproofing of foundation walls
This type of waterproofing is best done from the beginning of construction. Then water would not be a problem for you and extra time and money would not be required.
To carry out external waterproofing, they dig out the foundation. Then it is glued or coated with special means. There are several types:
- Bituminous mastics. As for bitumen, during operation it becomes less elastic and weak. This leads to cracks.
- plasticizers. Buyers “peck” at them because of the low cost. These products do not provide reliable protection and must be replaced every 5 years.
- Hot mastics. They are based on oil bitumen, polypropylene and polyethylene.
- Styrofoam board.
- Liquid rubber.
What threatens the flooding of the basement of an apartment building
In accordance with the 36th Art. of the Housing Code of the Russian Federation, the basement, located in a multi-storey building, acts as a common shared property of residents. Therefore, if a flood occurs, first of all, you need to contact the management company of the apartment building, which is responsible for its condition. After all, the lack of timely measures taken can lead to unpleasant consequences:
- in the course of stagnant water in the basement, unpleasant odors are formed at the lower level;
- fungus, mold appears, which is dangerous for the health and life of residents;
- a favorable environment is formed for the life of various insects - mosquitoes, midges, fleas;
- under the influence of moisture, the foundation of the room is slowly but surely destroyed;
- since not only household utensils and salting for the winter are stored in the basement, but important equipment, technical equipment that serves for uninterrupted supply of water and heat, all this can break down and lead to disruptions in the supply of utilities throughout the house.
To prevent this from happening, it is necessary to neutralize the consequences of the flood in the basement as early as possible, immediately after the discovery of its signs.
Inaction of the management company
If during the inspection, the adoption of a decision by the expert commission, the drawing up of the relevant act, the managing organization still does not take any measures to resolve the circumstances and eliminate the causes and consequences of the flood in the basement, it is necessary to file complaints with the housing and communal services or the Criminal Code to higher authorities:
- state housing inspection (as a result of this, measures will be taken to check the activities of a particular company not only in relation to the flood that has occurred, but also to other objects, if neglect of duties on the part of the house manager is detected, the ZhI will impose sanctions);
- Rospotrebnadzor is an organization that protects consumer rights, so you can be sure that the flood in your house will be eliminated in the near future;
- prosecutor's office (to act through this instance should be only when the case needs a trial to identify and punish the perpetrators).
Attention
A flood in the basement of an MKD is an extremely unpleasant situation that requires urgent measures and actions from the parties concerned, i.e. from the residents. On the part of the Criminal Code, such problems are solved on their own extremely rarely. Even if the employees in this organization pleaded guilty, an additional examination should be carried out in order to assess the cause-and-effect relationships regarding the accident.
In the case of advance insurance of property that was in a flooded room, you must contact the insurer. If the money received from him is not enough to cover the losses, it is required to write an application to the court in order to withdraw the missing monetary amount from the culprit of what happened.
Ceiling
The roof for the cellar is usually made of less durable materials, since it is not constantly in the water, unlike walls and floors.
For its arrangement, you can use at least a slab, and as a maximum a beam, which will be treated with an antiseptic from a fungus (copper sulfate is also suitable).
A layer of clay is compacted from above, which, in turn, is covered with a waterproofing material, which can be an ordinary roofing material, and covered with soil taken from the pit during construction.
If the winters in the region are not snowy or the snow cover is blown away by the winds, you can additionally insulate the roof with a layer of dry leaves or sawdust.
Backfilling of the roof must be done after the installation of ventilation pipes.
Where to go if the basement of an apartment building is flooded
If water is found in the basement of your own house, entrance, you need to report this to the emergency service. Residents make a call to the control room and call locksmiths from the management company to the house. Upon arrival, they will fix this problem and eliminate the cause of the leak, if it is possible to do it on the spot. Next comes the act. It must be kept by the party that suffered until the damage caused during the flooding of the basement of an apartment building is repaired.

If you have any questions, you can chat with a lawyer for free at the bottom of the screen or call: +7 (499) 938-41-00 Moscow; +7 (812) 467-41-55 St. Petersburg; +7 (800) 350-23-69 ext.480 Free call for all Russia. If the management company does not take any measures to eliminate the consequences of a flood in the basement, you should contact the higher authorities
If the management company does not take any measures to eliminate the consequences of a flood in the basement, you should contact the higher authorities.
Drawing up an act on the flooding of the basement
After inspecting the scene and establishing the fact of the flood, the next step is to draw up an act on the flooding of the basement of an apartment building. Through this document, the cause-and-effect relationships of what happened are established, the amount of damage incurred is determined. The paper is compiled by the organization that maintains the apartment building. It can be ZhEK, ZhEU, UK, HOA, etc.
There is a specific template for drawing up an act on the flooding of the basement. But there is no rigidly fixed form.
An expert group is also made up of the employees of the Criminal Code, which undertakes to assess what happened and its consequences. It must consist of at least two people and include members of the Criminal Code and affected persons. It is they who are involved in the execution of the act, which will continue to act as a document for a detailed identification of losses in house property. Filling is carried out by hand in free form.
There is a set of information that must be contained in the application paper without fail:
- the address of the MKD where the flood occurred;
- personal data of members of the management company that are directly related to the expert commission;
- Full name of the persons who inspected the technical floor;
- the causative factor of the leak, established as a result of the inspection (if it is impossible to identify it, a note is made that an appraisal examination is required);
- full descriptive characteristics of damage;
- a list of property items that have deteriorated;
- date and signatures of all persons involved in the preparation of the document.
IMPORTANT
It is worth considering that the creation of the act must occur no later than 12 hours from the moment of calling the emergency service or the Criminal Code.

Stages of work
The choice of the most effective drugs
Processing without risk to your health and the health of your loved ones
Constant monitoring of each work performed
What is the procedure for?
Sanitizing mold from basements of residential buildings, garages, cottages is the best way to eliminate many problems that occur indoors. It can be carried out both independently and with the help of specialists.
In the second case, the processing of basements of residential buildings is carried out by professionals. They have effective chemicals and equipment in their arsenal.
Of course, the disinfection of basements, carried out by specialists, will give a guaranteed result.
This procedure is carried out in several cases. The most common of them are:
- flooding of the premises;
- the presence of fungus, mold, dampness on surfaces;
- the appearance of mosquitoes in the house;
- the presence of cockroaches, bedbugs, fleas;
- appearance of rats.
Disinfection of the basement of a residential building can eliminate all these problems. The procedure will give not only cleanliness, it will serve as a guarantee of getting rid of viruses and infections that are spread by dangerous animals and insects, it may also be necessary to treat the room for fleas.
Features of the
Sanitizing the basement after a clogged sewer or when parasites appear is carried out as follows. Specialists in impenetrable suits and masks arrive at the site and carry out cleaning in several stages. The first one is preparatory.
If disinfection is carried out after a sewer break, then the specialists first pump out the water.
Only after that, a comprehensive cleaning of the premises from debris is carried out. It is removed not only from the floor, but also from walls, ceilings, pipes, windows, etc.
, after which all the garbage is transported.
This is followed by processing the basement after flooding with sewers. To do this, use effective means that are safe for human life and health.
Their use is a guarantee of long-term cleanliness and sanitary hygiene of the premises.
Formaldehyde, sulfur, fluorine-containing pastes or bleach have proven to be the most effective in cleaning.
But the choice of a particular drug depends on the problem that occurred in the room. For example, the processing of basement walls after flooding and the disinfection of an apartment will be carried out in different ways.
Benefits of hiring specialists
