Finishing exactly this part of the entire pool design needs to be given special attention. And first of all because of the fact that it constantly( by definition) is water. But before considering the order of waterproofing from the inside, it is necessary to understand what is best used to create a protective layer.
Waterproofing materials
The assortment of the corresponding products is impressive. In general, we focus on such indicators of the appropriateness of using products, as the possibility of doing all the work with their own hands( and, preferably, without the use of special equipment) and the cost of the goods. Nevertheless, it is necessary to point out a number of the moments connected with the features of the pool operation. This will help with choosing the best waterproofing option.
What to take into account
In water, however preliminary it may be, including chemical treatment, always contain impurities of various compounds, some of which are aggressive and can react with waterproofing material. With the inner finish of the bowl, this is especially important, because by definition, this part of the basin will almost always have direct contact with the liquid.
Specificity of the functioning of this hydraulic structure is that periodically the water should be updated. It is necessary, first of all, from the point of view of sanitation. This means that it will be regularly discharged with subsequent filling of the bowl, which, because of this, will not only be subjected to static, but also dynamic loads, and very significant. And they directly affect the integrity of the waterproofing. Based on this feature of the pool operation, it is advisable to use materials that, after installation, create a monolithic( seamless) protective layer.
Repairability. Here much depends on the size of the reservoir. If they are impressive, then when choosing the material you need to take into account whether there is the possibility of eliminating the defect of this protection by a "point" method. It is clear that replacing the entire layer( monolithic "canvas") in pools with large linear parameters is an exercise that is both complex and expensive.
Films
These materials include polyethylene roll products, which are universally used in the private sector. They are used both for waterproofing, and for covering small areas to create a greenhouse effect. The price is practically the lowest among analogues.
For example, 100 m cloth width of 3 m will cost from 2 050 rubles .A film of PVC is more expensive for 600 - 700 rubles / roll.
Bole quality, but also expensive are membrane-type waterproofing materials. Their plus is that they are available in different sizes, so pick up the dimensions of the canvas so as to cover the entire bowl with a single layer is not difficult. But again, if damaged, you will have to replace the entire membrane."Spot" repair of such products( at least with their own hands), as a rule, is inefficient, since the patch will not last long. Approximate cost - from 250 rubles / m².
Mastic compositions
This waterproofing is classified as "lubricating" and "penetrating".As an example, you can bring products under the brands Penetron, Ksaypeks, although this is not the only means that are available. People without sufficient experience, and even "spurred on" by advertising, are guided by the advantages of such materials and use them for finishing pools from the inside. Indeed, working with mastics is simple, and convenient.
Bitumen
This rather common material, especially in the private sector, is not recommended for waterproofing pools. It suffices to point out a number of significant shortcomings. Firstly, , low adhesion, therefore, based on the protective layer will not hold firmly. Secondly, , chemical composition, means there is a possibility of releasing some harmful substances into the water. Thirdly, , the fragility of such waterproofing.
That's why, despite the multifaceted application of bitumen in the construction and repair areas, it is not recommended to use it from the inside for swimming pools.
Liquid rubber
Probably, this is one of the best options. All the advantages of such compositions( and there are quite a few of them) can be found in the article devoted to the characteristics of liquid rubber. It is enough to point out that the layer is absolutely harmless from the ecological point of view, seamless, and the installation does not present any complexity. Moreover, several options - using a sprayer or a coating( roller or brush).Yes, maintainability is excellent.
The cost of liquid rubber - from 53 rubles / liter.
pastes. They are referred to the category of coating materials. Unlike mastics, they are applied more thickly. But they are relatively expensive. Plus, they are applied only after the reinforcing mesh is laid.
Cost of paste - from 265 rubles / kg.
There are a number of other materials that relate to waterproofing - bentonite mats, liquid glass and a number of others. Who are interested in the characteristics and prices, will find the relevant information on our website. But from the point of view of "their own hands", and also because of a number of shortcomings, it is hardly worthwhile to use such products when decorating the pool bowl from the inside.
Waterproofing order
The specifics of work with this or that material are specified by the manufacturer, and all necessary information is contained in the attached instruction. Therefore, it is sufficient to consider the algorithm of actions for the installation of waterproofing.
Preparation of
solution Even at this stage it is necessary to take into account the recommendations, if we talk about the integrated waterproofing of the pool. By the way, it is she who is considered the most reliable.
- Given the significant load on the bowl, the cement brand must be at least M400.
- In the solution it is necessary to introduce additives( plasticizers), which reduce the ability of the artificial stone to moisture absorption.
- As a filler, use fine-grained materials. This will then allow a more qualitative leveling( smoothing) of the internal surface of the pool.
Plastering
The inside of the basin is made from the inside only after it has completely cured( the concrete has dried).If the use of roll( film) materials is intended as a waterproofing, the surface of the plaster layer should ideally be leveled. The slightest projection in the future can lead to rupture of the coating.
If the pool is located on the territory, then before starting work on it you need to install at least a temporary canopy.
Waterproofing installation
According to the material manufacturer's recommendations. For greater reliability it is recommended not to be limited to just one layer.
Quality control
After full availability of the pool, it is filled with water, and completely. On its edge on the side you need to put a mark( for example, a marker).If after a couple of hours the water level remained unchanged, then we can assume that the waterproofing is reliable. And in the case of a crack and a large leak, it will be seen immediately.
Conclusion
There is nothing complicated in this work. The main thing is to choose the right material for waterproofing taking into account all the features of a specific pool( its dimensions, installation location, and so on).
