How to make waterproofing the floor in the apartment in front of the screed - materials and technology

Techniques waterproofing surfaces, there are quite a few, since the sale is a huge range of relevant products, the use of which is characterized by its specificity.But when it comes to a city apartment, the choice is not so big.And the main reason - in the ceiling, or rather, at full load, which can withstand the plate.

, you need to figure out what goals this stage of repair (or an additional arrangement of the dwelling) to more clearly understand how to make really high-quality waterproofing the floor under the screed in the apartment.The fact that each room is characterized by the features of the use and location of the house, so to reduce costs have to approach the issue of isolation rationally, based on the feasibility of the acquisition and use of various materials with regard to the form of future ties.

What is waterproofing floors

First , to avoid water leaks during installation leveling layer, if it is done on a "wet" technology.In this case, waterproofing acts as a kind of barrier, because the water contained in the solution will tend to soak into the floor slab and leak through the existing cracks, joints of the lower floor.

Second , to insure the future of trouble with the neighbors because of the fault (leakage) in the utilities.This is especially true for areas where it is constantly produced water analysis and, therefore, established a sufficient number of different plumbing (kitchen, bathroom and toilets).Plus - the risk of spill water on the floor, because of this no one is safe.What to do if you have filled in the neighbors above, please click here.

Third , to prevent penetration of water vapor from the lower floor of the room.It is particularly important for areas with excessive humidity (as they are on the riser of each other) and the apartments above the basement (ground floor).

Argued that the waterproofing is needed only for "very wet" rooms (bathroom, and so on).But it overlooked a point that in any apartment, the rooms, radiators installed, the pipe laid.Perhaps in the hallway to equip such a protective layer, and does not make sense, but in all other areas is desirable.Hardly anyone satisfied with the prospect to communicate with neighbors of the ground floor in a raised voice, and even pay them repair the ceiling (and perhaps to a greater extent) in their home.

Methods of waterproofing flat

floors Base preparation

question is quite simple, and there is no need to explain that the first floor "is laid bare" and cleaned (washed) from any debris and dirt.Unfortunately, it is fairly common, but somewhat primitive view of the preparation of the problem.Task zealous owner - make a full audit of plates and joints places.After all the activities must be carried out comprehensively.

If we decided to spend the time and materials to such large-scale work (by the way, with complete removal of furniture and everything else), and you need to do everything on the conscience.What's the use, if properly laid, for example, a film.The remaining gap in the ceiling - the penetration of noise and heat loss.It turns out that solving one problem, the rest (acoustic and thermal insulation), we leave for the next time.It is illogical.

impregnation

Given that the overlap in the homes of the w / w plates, it is advisable to make their treatment with the penetrating waterproofing.Why, stated "Third."Couples can gradually erode the concrete, and it is desirable to protect.In principle, the cost is inexpensive.

example, means «Sanisil» (domestic products) sells for about 378 rubles / kg .Estimated consumption - 0,7 l / m².Not less popular «Betonokontakt» , and is much cheaper ( 12 kg - from 760 rubles ).

Given that the impregnation will have to do for small spaces only (humid) - bathroom, kitchen, toilet - the cost is not so big, but it is quite reasonable.By the way, is characteristic of these rooms smell of damp eventually disappear.

If impregnation for some reason decided not to do, it is desirable to process slabs composition of the soil.

waterproofing Construction

Roll materials

can purchase film p / e (the budget option), waterproofing, polyisobutylene, or something like that - the choice is.But the installation of the technology is the same.

On the wall is a small "overlap", ie, the film is wrapped up.The value is determined by the thickness of the screed.waterproofing material should be slightly above the "finish" the coating to prevent penetration of water down, for example, wet cleaning or leaks in plumbing.Even if the film after the final finishing of floors and will stick to the sides of the room, after fixing the skirting boards it will not be visible.

are commercially available and waterproofing membranes.They are convenient in that one cloth covered the entire floor, and no additional work is required.Their cost is slightly higher, but the insulation is more reliable.

should be familiar with the manufacturer's recommendations, since some materials can be assembled in one layer (polymer), the other - at least two (unless, of course, take care about the quality).

lubricative

With them, it is advisable to work in areas with excessive humidity, and placed on top of the screed (although you can use instead of film).The procedure was the same, only the processing of the floor and the bottom edge wall (strip) is made mastic compositions.For example, "water stop."Packaging 20 kg costs about 480 rubles, and consumption - about 1.3 kg / m².

Perhaps this is all acceptable options for a city apartment.Encountered on the Internet recommendations for waterproofing various thin screed, plaster compositions cause a lot of questions.And chief among them - how to increase the load on the overlap and how to determine their own degree of wear plates?From the point of view of the author, to experiment undesirable.That information, which is described in the article is enough to achieve an effective waterproofing floors in all rooms.
