In this article we will describe what is the waterproofing of the floors of the bathroom and what are the acts of hidden works in the context of the waterproofing of the bathroom.
Actually, this is the most famous act of hidden works, because most of the work is done in the sanitation zone, such as those that require the admission of raw. And this document is also required by the Housing Inspectorate to consist of documents that will be surrendered.
It is quite simple to fill out: there is the name of the works, the apartment number, the address, the design organization that developed the redevelopment project, the general contractor organization, who produced the work (it is necessary to finish the construction organization) and, in fact, the works themselves (waterproofing the bathroom floor).
We wrote the number of the project, concerning which we did, and further: "When performing the work, materials are applied in accordance with the project specification".
There are two options
You can write "according to the project specification". Well, actually, this means: look at the project, that's what's there, then put it.
And you can write the material itself, i.e. conditionally there is a hydroisol in two layers or a coating waterproofing or an overlying waterproofing, well. various materials, which are applied, such and write.
Date of commencement of works, date of completion of work. Well and further, the decision of the commission: finishing works have resolved.
There are two seals, i.e. a construction company that made acts of hidden work on waterproofing, puts its seal with a signature, and the design company that was developing the redevelopment project, in fact, puts its seal in confirmation that the waterproofing is done.
As we have said, the act is very necessary. Very often there are cases of leaks either during repair work, or after repair works, i.e. The act is a confirmation that the waterproofing is actually done, and it is executed correctly, etc.
If we talk about the process, we think that builders know how to do it. You must somehow know. But basically - it is correct.
Oble waterproofing works poorly, it is better, of course, to apply a waterproofing with an inset on the walls for 15-20 cm.
Why does the waterproofing work poorly?
Because just badly smear basically. There it is necessary to smear so that the normal layer remains. Then, when the screed is poured, another screed is pressed with expanded clay and holes are formed.
Oaklechnaya, of course, the most relevant. This is an old way, even from those years in which we probably have not lived yet. At least we are for sure. Moreover, there are no SNiPs to the lubricating waterproofing. SNiPy still from the 70-ies, and there were not such completely materials applied.
As we have already said, the Housing Inspectorate will not accept the completion of the redevelopment without this act. In addition to this act, an act of hidden work on soundproofing, an act of hidden work on an opening in the bearing wall, if it was, is still often given. The construction repair log is being filled. Here is a magazine.
This we have already deviated a little from the act, but God is with him. We will tell more.
There's a lot of things. Here they put all the seals, and builders, and designers. If the acts of hidden work on the waterproofing somehow (if there is a SRO admission) can be filled in, sorted out. Usually they give us empty forms, and we fill in, because it is impossible for them to explain how to fill this act.
That log of repair and construction works introduces them simply into a state of general stupor. Those. when they see it, they just stop understanding something and say: "No, no, no. Here somehow help us. " Neither links do not save (the site has already described and examples of some ... can not).
We have to fill in all the time to us, the coordinators. It is necessary to hand over certificates of hidden works to the Housing Inspectorate, a completed log of repair and construction works, and, in fact, a contract of work and admission of the SRO to the construction company.
A little later, the construction company and designers will have to sign acts on the completed reorganization, also printing. Those. there are a lot of stamps to put in the process.
In principle, that's all. And, by the way, if the work is carried out by unlicensed builders, then our organization will be able to help you with the supervision of the work of your builders with the provision of all relevant acts for both waterproofing and soundproofing. Those. you will be carried out work in accordance with the requirements of the Housing Inspectorate.

Usually the redevelopment of the apartment affects the bathroom or bathroom. When expanding or moving these rooms, you must make a waterproofing floor (otherwise you can pour the neighbors from the bottom).
Re-planning and laying of waterproofing is a very important process, requiring appropriate documentation. This condition is fixed in clause 2.2.6 of Appendix 1 of the APM No 508 in edition 840 ("Modification of the construction of floors"). It is important to understand that the process of redevelopment is quite long. It begins with the collection of documentation, and ends with the acceptance of works by a special commission signing an act on the completed reorganization and making changes to the BTI documents.
When the housing inspection coordinates all the nuances, the owner is given permission to redevelop. At this stage, you can implement all design solutions. At the same time, it is necessary to draw up an act for hidden works on waterproofing the floor. This condition is set out in Appendix 7 of APM No. 508 ("List of acts of survey of hidden works ... presented to the commissions upon completion of re-planning ...").
The act of hidden works on the waterproofing of the floor is needed to confirm that the redevelopment of the apartment is carried out in accordance with all established norms and rules. Without it, the acceptance commission will not approve the changes. In addition, the inspector has every right to open the floor to make sure that the waterproofing is present. If there are violations, the commission sets a deadline for their correction and conducts another check.
Where to get a sample of such an act? The form can be downloaded. A representative of the repair firm must sign it. It is important that this organization has access to the SRO, which gives the right to responsible work. At the same time, ordinary workers' brigades without an admission do not have the right to carry out a survey of hidden works. Then the act is signed by the employee of the project organization, checking the correctness of the laying until it is covered with a floor covering.
In some cases, the installed waterproofing is checked. For this, the coating is poured in water for several hours and looks for leaks. After that, the test certificate of the waterproofing coating is made. In this situation it is desirable to take a few photos. Examples of filling are presented below.
In the process of performing the work, the performer independently completes this act. He confirms that the waterproofing was carried out taking into account all the requirements of the project and SNIP. Then the document is signed by the representatives of the repair organization and the DeS.
If the owner of the apartment does repairs on his own, then he needs to call a commission from the representatives of housing and utilities and other professionals to certify this act. Otherwise, it will be difficult to legalize the redevelopment.
It is important to understand that improper installation of the waterproofing layer can cause water leakage to the lower floors. For unauthorized redevelopment of a bathroom or a bathroom is subject to a fine.
In each house under construction or in an apartment there are rooms that need waterproofing. Such work is carried out in accordance with the project documentation and with the rules of SNiP 3.01.01-85. According to these documents, any work, the quality of which can be checked only before the beginning of further construction or repair work, must have a properly executed and signed by the responsible persons an act for waterproofing. Even the redevelopment in your own apartment falls under this requirement, when it comes to the bathroom.
Waterproofing is subject to objects, somehow in contact with moisture. Do not feel sorry for the funds for good waterproofing. It takes only 1-3% of all construction costs, but depends on it the reliability and durability of the entire building.
Foundation of a building
The duration of the operation of the structure is strongly influenced by the quality of the erection of the foundation. This underground part of the building is constantly under the influence of ground and atmospheric moisture, which causes cracks in the porous structure of the material, capable of destroying the concrete base and creating the need to re-unearth the foundation and make unscheduled repairs. Ignoring such problems is impossible, but even small microcracks threaten irreversible processes in the constructed walls. The moisture that enters the inside of concrete or brickwork creates a favorable environment for reproduction of the fungus, which can be very difficult to remove, but is often impossible at all.
Important: Mold is not only the destruction of the structure, but also a significant harm to the health of people in the building who can get serious diseases by inhaling fungus spores.
To the house could stand for many years, the foundation must be protected from water impact. This is ensured by competent waterproofing
Basement
Groundwater, washing away the concrete basement of the basement from below, can prematurely damage the structure and flood the room through joints and cracks. Steam and condensate, created from the difference in external and internal temperatures, penetrate the walls of the building, provoking the appearance of rot and destruction. Salts contained in thawed waters can cause corrosion of metal elements and fittings. The use of waterproofing contributes to reducing the impact of such factors and allows the use of the basement as an apartment, though not residential, but suitable for various other purposes.
The main causes of dampness in the basement are: lack of waterproofing, incorrectly made previously waterproofing basement, substandard waterproofing materials or incorrect technology of their use
Roof construction
From the effects of atmospheric precipitation, the roof elements gradually deteriorate, their moisture resistance decreases. The water begins to fall under the external coating, which leads to rotting of the main elements of the rafter system. Flow into the interior leads to damage to the ceilings and humidity in the living rooms.
Important: If the tightness is insufficient, the roof insulation also decreases, and you have to spend more money on heating the interior.
If you do not work on the waterproofing in time, then atmospheric precipitation can provoke a rapid wear of the roof cover, which will shorten the life of the entire roof
Bathroom floor
When repairing apartments often there is a need for redevelopment of bathrooms. Adding additional space to this room due to auxiliary rooms entails mandatory sealing of the floors. The penetration of water and moisture, which necessarily happens on the floor of this room, in the lower layers of the floors threatens to damage the environment of the lower neighbors. And they certainly will complain in housing and communal services, which have the right to demand documents for redevelopment, conflicts will begin.
Waterproofing the floor in the bathroom is an extremely important stage of construction
Swimming pool or sauna
The construction of the pool both indoors and outdoors requires mandatory waterproofing. The flow of the outdoor pool is fraught with a constant decrease in the water level, ingress of thawed and groundwaters unsuitable for bathing. With an internal pool, as with floors in the bathroom, it is possible to leak water to the lower floors.
Saunas mean moisture not only on the floors, but also in the whole room, and therefore waterproof should additionally the entire area of the walls and ceiling.
When building a swimming pool, one of the first requirements for it is a high-quality waterproofing, on which the strength and durability of the whole structure depends
What documents need to be issued when performing repair work
To avoid all these problems and extend the life of your buildings and premises, you must carefully approach the work on waterproofing. If the repair is made by the construction company, the first thing is to prepare a budget for the waterproofing, which brings in the necessary materials and determines the prices for the alteration. The organization must necessarily belong to the SRO, whose membership gives it the right to produce this type of construction work and obliges to be responsible for the quality of the orders it performs.
The form of the certificate and samples of filling can be downloaded on the Internet
In the process of completing the stages of such an order, the contractor himself fills the act of hidden work on the waterproofing. The document confirms that the waterproofing is done taking into account all the requirements of the SNiP and the draft. To sign it should specialists of the design, repair organization and Dez.
When drawing up estimates in the computer program, you need to take into account that the VAT tax is put in a separate column of additional costs
If the repair is done by the tenant himself, he will have to call a commission from representatives of the housing and utilities and other specialists to certify this act. Otherwise, it will be difficult to legalize the redevelopment, since in the absence of an act of hidden work, officials may require the opening of some of the floors to control the waterproofing. Breaking an already made floor covering, of course, is unpleasant. You can use in this case the offers of special firms that provide services in this area.
