    Swimming pool waterproofing

    Water from underfloor pools
    Not everyone can request a pool. This is why so many people have to do it themselves. This process is very laborious and complicated. And at the final stage, you need to take care of the most important thing - waterproofing. It affects not only reliability, but also the durability of the structure as a whole. Let's talk about what is and what the waterproofing of the pool is for, and how to cope with this task without the involvement of specialists.

    On the purpose and types of waterproofing
    Before proceeding with the practical part of the work, I would like to talk a little more about the functions performed by waterproofing. To do this, it is necessary to understand its types. So, pool waterproofing is of two types: external and internal.

    It can be estimated that external insulation is used to protect the structure from the effects of groundwater. Meanwhile, internal water leakage is necessary to ensure that the water collected in the pool does not destroy the concrete structure from the inside. However, if you are going to build a pool inside a building, then you do not need to use an external waterproofing.

    It must be understood that any kind of isolation does not solve all problems. Yes, it will protect against moisture from any side, but no more. If a swimming pool is made with deflectors, then waterproofing does not help here.

    Slits of 3 mm and more can be formed. This will lead to moisture on the concrete base, which will begin the process of its gradual destruction.

    It is often required to use various materials for waterproofing (coatings, rolls). For example, insulation requires a carefully prepared container and its base. In some cases, I can use a single component mixture, in other cases I can use a two component mixture based on polymer cement. This type is used for internal processing. In outdoor work, roll materials are used. Since they have poor adhesion to some surfaces, then it is useless to use them for internal work.

    You have already figured out what the waterproofing is for. Now I would like to consider the technology of the internal and external business. All work can be done manually, but this requires a little theoretical knowledge.

    The inner layer of waterproofing is performed immediately before the swimming pool is finished. For this, reinforced coatings are used. They are necessary to prevent moisture from filtering through a container inside the structure, which can lead to its destruction.

    External waterproofing is achieved by introducing plastics into the concrete mixture. The purpose of the latter is to increase the strength and water resistance of the bowl. Work should be done during construction, if there is no such possibility, then at the stage of repair work. In any case, waterproofing of the concrete pool is mandatory. Many experts assure that the quality of waterproofing should not be so strong and elastic, as creating a monolithic layer that reliably protects against the ingress of moisture.

    Now I would like to talk about how to protect the concrete substrate from moisture from the inside. This waterproofing is done under the tiles. After the bowl is filled and formed, it must be frozen and dried completely. After that, it is possible to apply waterproofing. Suitable for almost any elastic mixtures. It is better to apply it in several layers, as it is more reliable. To prevent leakage in any area, waterproofing should be distributed evenly along the bottom and walls of the bowl.

    Basically, waterproofing of underfloor pools is very simple and fast. The main thing is to pay attention to the quality of the mixture and to apply it as evenly as possible. After it dries, you need to check the pool. For this, it is filled with water, which after a while it is released. After that, you can draw some conclusions. If a leak is found, it can be covered.

    Swimming pool waterproofing: materials and everything about them
    The abundance of modern waterproofing materials is simply amazing. Sometimes it may seem that it is simply impossible to choose, because there are so many of them. But it is very important to pay attention to the design features of the bowl. And only then proceed to the choice of insulation materials.

    The most popular and at the same time relatively inexpensive material is a film of high strength. It has a lot of advantages, but all of them can cross it with one minus. The point is that if at least one small hole appears in the film, then an entire layer has to be changed.

    It is impossible not to pay attention to the membrane material. This movie is PVC, TBW and others. This waterproofing has a service life of about 50 years, and is also environmentally friendly. However, it is very difficult to install PVC film independently, and the material itself is very expensive.

    In most cases, plastics are not used as independent waterproofing for many reasons. The fact is that it does not always give the correct result. But here during the repair inside the pool, without them it is difficult to do. Any local damage should be covered with mastic. It is economical and reliable. It is recommended to purchase plastic materials from the following manufacturers: "Psykpez9". Penetron, and Calmatron.

    Bentonite mats are suitable as the main waterproofing. But it is necessary to understand that the bentonite granules are washed off by the pressure of water. In addition, the maximum load requirements may not be exceeded, which should not exceed 200 kg / m2. This material is very resistant to mechanical damage and has the ability to regenerate.

    Often waterproofing is carried out after the completion of construction work. First, it is desirable to perform external manipulations. For this, the walls of the pool are cleaned of soil and residues from the concrete mixture. Cleaning must be done to a depth of cushion around the perimeter. The next step is to use a perforator to expand the seams of the walls to a depth of 5 cm. In the obtained holes, put mastic, which must be carefully leveled. The outer walls need to be slightly moistened with water, and after about 15 minutes apply penetrating insulation. After 24 hours, a second coat is applied. In this case, the thickness of each layer should be of the order of 2 mm. In principle, the waterproofing of the pool with its own hands from the outside is almost complete. The walls can also be covered with liquid rubber. In the end, the walls are covered with soil, preferably not clay, but clay.

    On how to carry out external and internal waterproofing works. If the material is chosen correctly, and technology is observed, then everything should be in order. For example, liquid waterproofing for swimming pools often washed away, but resistant to mechanical damage, but with a film due to the large pressure of water nothing will happen, but any damage will require repair. In any case, it is necessary for concrete concrete swimming pools. So you can protect the foundation from premature damage. Remember that it is better to do this work not during the repair, but during the period of construction work. So it greatly increases the effectiveness of waterproofing.

    The water leaks from the swimming pool
    Swimming pools are increasingly appearing in country houses and even in the suburbs, as they are before personal cars, moving from the rank of luxury items to the elements essential to living in a fully residential environment. Of course, most of our compatriots are funding for a stylish "key pool" from leading manufacturers and sharp companies are not enough. However, if you want the minimum investment, you can equip your entire shower space yourself or with some outside help.

    One of the most important stages of work is the waterproofing of the swimming pool. And the quality performance of these works will ensure the main thing - the full operation of the facility. Those who do high-quality protection of the walls and the bottom of the pool with inexpensive materials will also receive a huge bonus, apart from tangible savings for the family budget. This is the most sincere gratitude of relatives, friends and relatives. And what could be more valuable?

    We independently carry out waterproofing of the pool
    Pool, like any other room in the house or on the site, requires the utmost accuracy in performing protection against leaks. Moreover, waterproofing works should not only provide protection from leakage on the inside, but also - and at least importantly - outside. Entering groundwater (far from pure!) Into a swimming pool can cause major problems with the health of the owners of the house, and especially - in children.

    Therefore, competent waterproofing of a pool is perhaps more important than a super duper finish with expensive tiles. It will be very painful after a year to drop it to fix the sheep with insulation. The introductory word is over. Now on business.

    Materials for waterproofing the pool
    In the sink, water creates not only a direct impact on the material from the finish, but also, first of all, significant loads on the frame of the structure. Therefore, the waterproofing materials used should not only pass moisture, but also be very strong to deformations, temperature changes and resistant to other mechanical effects and influences. That is, the waterproofing of the pool bowl should be very strong, but at the same time - elastic. And these criteria are not met by all materials on the market. This is due to the fact that the basic material that is used for the device of a pot is monolithic concrete, reinforced concrete, and less often brick. The most suitable option is the insulation of a concrete pool, which we will talk about. Now we will choose the appropriate options. There are only a few:

    - materials based on bitumen;
    - Cement waterproofing materials.
    - liquid rubber;
    - liquid glass;
    - Penetrating waterproofing.
    Membranes.
    There are two options for how to waterproof the pool: outside and walls from the inside. Naturally, it is necessary to fulfill both. External insulation will protect the concrete frame structure from the ground, rain and melt water. And the treatment of walls from the inside - exclusion of internal leaks.

    For external insulation, in order to save money, cheaper materials such as bitumen mastic, roofing material, cement mortar, and even PVC film are often used. This is a very big mistake.

    First, these materials do not provide 100% protection of concrete - due to the large number of joints and properties of the material, and even the microscopic part of the moisture penetrates into the pores of the concrete, destroying its structure, causing corrosion of the rebar and, ultimately, it will also damage the internal insulation as a result. To deform the frame.

    Secondly, the listed material has a limited service life - from 10 (film) to 20 years (mastic, rubyoid), after which it loses its protective properties (crack, etc.). Then we have to perform drilling of the outer walls of the bathroom and updating or replacing the insulation.

    Thirdly, for waterproofing pool materials, they should be sufficiently elastic, since they are reinforced concrete structures that are exposed to many negative effects: soil shrinkage and sharp temperature changes. And the insulation materials must be stretched accordingly, and then shrunk without damage.

    The fourth reason is that the mentioned materials often simply peel off the concrete surface, so the walls must be pressed, which increases costs.
