The swimming pool is both a decoration of a personal plot or a house, and a place for sports, recreation and entertainment. Let's make a reservation - a good pool filled with invigorating moisture sparkling in the light of sunlight or LED lamps. And not the one that stands without water, representing an unattractive depression in the ground or in the floor. The durability of the pool is primarily determined by its waterproofing.

Therefore, if you are building a pool from scratch or decide to restore an old one, you are interested in do-it-yourself waterproofing, then you need to know what and what to choose from, and what surfaces generally need to be waterproofed.

Pool waterproofing: materials

There are a lot of materials, and which one is suitable for your pool depends on the area in which you live and the climate, type of pool you have.

The main types of waterproofing:

• PVC film;

• penetrating waterproofing;
• coating waterproofing;
• liquid glass;

• liquid rubber;

• bitumen-based materials (in comparison with the latest developments, they lose significantly, and therefore are almost never used, although they were previously widely used);
• gluing insulation made of bitumen-polymer compositions, applied hot.

Pool waterproofing methods

Allocate external and internal waterproofing.

External waterproofing of the pool is used to protect the pool bowl from groundwater. At the construction stage, plasticizers are added to the concrete, which increase its strength and water resistance.

The second option - the concrete is covered with penetrating compounds. For external waterproofing of pools with their own hands, Izofast and Tenabit-M, Penetron and Infiltron mastics are used. These are those mixtures, which include sand, chemical additives (plasticizers) and cement. The result - the mixture penetrates deeply into the concrete base of the future pool, filling the smallest cracks and micropores, strengthening its physical and chemical properties.

External waterproofing of the pool: technology

If there is a need to repair the pool, then the external waterproofing of the pool is a very important stage.

1. Along the perimeter of the pool bowl, they dig out the walls.

2. They are cleaned of contaminants and inspected.

3. In places where the concrete began to collapse, peel off, cleaning is also carried out.

4. Seams and cracks are expanded, cleaned, in order to be subsequently treated with a material for waterproofing the seams.

5. The outer walls of the pool are first covered with penetrating, then coated and elastic insulation (if you use cement-based waterproofing) and coated and insulating if you use bitumen-polymer mastic, which is also called liquid rubber.

Internal waterproofing of the pool: technology

1. The concrete base is cleaned of dust and debris.

2. Seams and cracks are expanded and treated with materials to seal the seams. The joints are glued with sealing tapes.

3. The surface is leveled. To do this, the surface is plastered: the walls are treated with waterproof compounds for pools, and the bottom is treated with a self-leveling cement mixture.

4. The surface is primed with a primer using a roller or brush. After 3-4 hours, you can start applying subsequent layers.

5. The dry mixture is diluted with water to the consistency of thin sour cream (the ratio of liquid and dry material must be strictly observed, taking into account the instructions for the specific material indicated on the packaging).

6. A solution is applied to the previously prepared base with a brush or sprayer.

7. Especially carefully you need to process:

• seams between the bottom and walls of the pool;
• seams resulting from concreting;
• places where communications are introduced;
• cracks in the concrete base;
• formwork fixing holes.

It is important to note here that in order to treat the pool with waterproofing compounds, it is necessary to use them in a complex: first, a penetrating solution, and then a coating solution. After applying the penetrating composition, the surface is treated with a solution of hydrochloric acid (4-5%). Then everything is washed off with water, and after another 30 minutes, treatment is carried out with a 4-5% solution of soda ash. Only after that is applied the coating mastic. Two-component elastic waterproofing is applied with a thickness of 2.5-4 mm.

If you use Hyperdesmo liquid waterproofing, you will need to apply 3 layers. After 6 hours, but no later than a day later (when the layer polymerizes, but will be slightly sticky), a reinforcing mesh is laid, and a second layer is poured over it. After that, fine-grained sand is poured onto the polymer layer that has not yet completely solidified to improve adhesion - adhesion to the next layer. If the coating is being prepared for tiles, then the surfaces are allowed to dry completely, the sand is brushed off and the tiles are laid.

If a tile is not provided, then a third layer of polymer is applied on top of the second one, to which pigments are added to obtain the desired color. Sometimes mastics of different colors are mixed to obtain the desired pattern. Since the third layer still needs to be strengthened, the A-3000 accelerator is added to the finishing coating solution at the rate of 1 liter of accelerator per 25 kg of mastic. Everything is thoroughly mixed with a mixer to prevent the appearance of a bubble. The mass must be homogeneous. Then it is evenly distributed with the help of a doctor blade and “spiked” - it is carried out over the mixture with a roller with spikes. Everything resembles the technology of applying self-leveling floors.

8. After treating the pool surfaces with waterproofing, they should not be walked on, and the temperature should not be lower than 0 ° C for 3 days.

9. In order to avoid peeling and cracking of the material, in some cases (when using Penetron and other means), the surface must be moistened for 3 days, and in the inner part of the pool (the one that will be under water pressure) almost up to 14 days. This is done by spraying water and covering the treated concrete surface with plastic wrap.

10. After all work is completed, the pool bowl is checked for leakage. For this, water is collected in it for 10 days. If no leaks are found, the water is drained, and the bottom is cleaned of possible debris and allowed to dry.

11. After drying, they start decorating the pool bowl with mosaics or tiles (if necessary).

Waterproofing mastics

Depending on the purpose, the following types of waterproofing materials are used.

Particular attention will need to be paid to seams, cracks and gaps. If the cracks are more than 0.4 mm, use the M600 injection clamp. Dry cracks or wet ones, PeneSplitSeal and PenePurFoam injection resins, Penekrit solution or Rubberflex one-component polyurethane sealant will help to get rid of them effectively.

Before waterproofing the pool, it is primed. To prime the base for applying a waterproofing material, use Gruntofol, AquaDyur or the like.

For external waterproofing of pools, do-it-yourself mastics Izofast and Tenabit-M are used, for internal - Hyperdesmo or Penetron, Cemizol 2EP and 2EN, Idrosilex Pronto, Polybit Polyflex and Ceresit.

This polymer-cement mastic creates an elastic, water-impervious layer on the concrete surface of the pool bowl, which additionally makes the concrete resistant to mechanical stress.

Pool waterproofing with liquid rubber

Liquid rubber is a bitumen-polymer mastic that is sprayed onto the surface, adheres well to it and provides good waterproofing properties.

It is also called a membrane coating. Such a material can combine the advantages of PVC membranes and liquid waterproofing. In this case, a continuous, well-adhered coating without seams will be obtained. It will be as pleasant to the touch as a PVC membrane, and as dense and durable as polymer-cement mastics. Liquid rubber can serve as a basis for further laying of mosaics or tiles, and maybe a topcoat. Colored materials are already being produced, which allows the use of liquid rubber without decoration.

Of the modern brands, Trowel Grade, TopCoat AnyColor, Roller Grade are common. These are bitumen-polymer emulsions, mastics, which are used for waterproofing both seams at the base of the pool and the entire pool.

Before applying liquid rubber, the surface is carefully leveled and treated with a degreasing compound. See point 7 of the Insulation of the pool section.

Then the bitumen-polymer coating is applied with a roller or brush - this is what those who will do the waterproofing of the concrete pool with their own hands do. When carrying out such work, professional builders use a compressor.

Pool waterproofing with liquid glass

In order for concrete to be more durable, as an option, liquid glass is added to it. This is the name of a solution of sodium and potassium silicates. This helps to strengthen the material, makes it resistant to mechanical damage and reduces moisture absorption. This procedure is carried out at the construction stage. But liquid glass is also used without cement: the surface is impregnated with it, which serves as protection against moisture, temperature, ultraviolet radiation and corrosion for a period of at least 5 years.

PVC membranes

Of the film waterproofing materials, the most progressive and reliable is PVC membranes. Such material combines waterproofing and decorative functions. It is a soft, durable, elastic film in a wide variety of colors. Every year new types of it appear - under the mosaic, under the marble, etc.

Such a film is resistant to mechanical damage, it tolerates well if the base under it is not perfectly even, the welds are strong. A geotextile sheet is usually laid under it, which hides all the irregularities that could adversely affect the waterproofing of the pool. Such material can be operated at temperatures from -50 to +80 degrees. The price of PVC membrane brand ALKORPLAN - 12-27 dollars per linear meter. It is used in combination with geotextiles, the price of which is $ 1 per meter.

No matter how strong the membrane is, this material can still be damaged under a combination of circumstances. You can make a hole in it on purpose or by accident. Therefore, mastics, liquid glass or liquid rubber are more often used for capital pools.

Gluing waterproofing

For this type of insulation, materials based on polymerized bitumen are used, which are applied hot. These are stekloizol, rubiteks and stekloelast. The material is durable, frost-resistant, not afraid of sunlight and has good extensibility, and hence increased strength.

When installing pool waterproofing, you need to evaluate your strengths. The chosen method of waterproofing can be quite laborious. Therefore, carefully study the technology of applying one or another waterproofing and choose the one that you can handle without involving specialists.

The pool is a small haven of paradise, at the mention of which, our imagination immediately draws a beautiful picture, where expanses of transparent water sparkle with the whole palette of reflections from the sun or artificial lighting. The pool is a multifunctional building that can be used as:

• element of decor for a house or a personal plot;
• sports ground;
• area for recreation and entertainment.

To ensure uninterrupted operation during the entire operational period, even during the construction process, you need to take care of the implementation swimming pool waterproofing, the purpose of which is to exclude the possibility of the destructive action of moisture.

Types of pool waterproofing

The waterproofing of the pool bowl implies the creation of a protective barrier both outside and inside the pool. Pool waterproofing is divided into the following types:

• internal is performed to protect the pool tank from water penetrating through poor-quality materials or cracks;
• external is performed to protect the pool from the destructive effects of groundwater, which, when penetrating into the pores of concrete, can destroy the entire internal waterproofing.

Choice type of waterproofing for the pool depends on the location of the hydraulic reservoir, humidity indicators, soil type.

The choice of waterproofing materials for the pool

At the present time, the market is represented by a huge range of materials for waterproofing. To make a rational decision in the matter of choice, it is necessary to focus on the design features of the pool.

Waterproofing materials for swimming pools represented by the following types:

Mortars based on cement

Such mixtures include three components:

• binder, in the form of cement;
• filler, in the form of fine quartz sand;
• polymer additives.
• The advantages are:

Such a variety in the choice of waterproofing materials will allow you to perform high-quality waterproofing of the pool with reliable protection against corrosion.

Entrust the waterproofing of the pool to the specialists of MasterHydro LLC

In order for the pool to serve for a long time and without problems, it is necessary to carry out waterproofing work and entrust it to the best specialists in this field. MasterHydro LLC will provide you with a complete package of solutions, taking into account the size of the pool, the material for its bowl, compliance with all technical regulations, using only high-quality materials and taking into account all the wishes of the client. Quickly, efficiently and with minimal material costs. Guarantee for high-quality waterproofing of the pool included as a nice addition.

Unfortunately, the concrete from which the bowls of artificial reservoirs are made is not a completely waterproof material. During setting, moisture evaporates from it, during pouring, insufficient compaction is possible, and during shrinkage, internal stress arises in it. These and other factors cause the concrete layer to be penetrated by microcracks, pores and capillaries. Through which water passes during operation - it flows out of the bowl, or vice versa, seeps into the container from the soil.

Therefore, for everyone who builds a pool, waterproofing is a very important concept. It is internal and external. The device of the latter is quite complex and time-consuming, therefore it is rarely used.

Waterproofing of pools is carried out in various ways

1. Films polymer-based: polypropylene, polyvinyl chloride, polyethylene, cellulose acetate, synthetic rubber, etc. Reinforced with polyester mesh, synthetic fibers or fiberglass. Differ in high mechanical durability (including to punctures), are insensitive to freezing and thawing. They are also resistant to preparations used for maintenance of swimming pools, UV rays and weather conditions.

2. Coating (penetrating) waterproofing of pools. Often used under ceramic tiles or mosaics. New materials that have appeared on the market have high adhesive (adhesion to the base) and physical and mechanical properties, due to which they create a reliable barrier to protect against groundwater penetration. A paste-like solution is applied to the inner surface of the bowl, penetrates into the pores of the concrete and clogs them. After contact with water, the material is activated and becomes waterproof.

3. Membrane waterproofing. A composition based on bitumen-latex compounds is sprayed onto the floor and walls in 2 layers. It is used as a supplement to the coating, takes on the main load of the water column.

4. Hydrophilic profiles. They are used in places of installation of embedded parts to eliminate water leaks due to different thermal expansion of concrete and pipe materials. They are made on the basis of polyofelin rubber or bentonite clays.

Now it has become very fashionable to have a swimming pool on your suburban area. Why not? And why not equip a full-fledged place for taking water procedures? Especially if you do it on your own or with some outside help. But, remember: the waterproofing of the pool must be completed on time. Otherwise, this "new-fangled thing" will not please you for long. Do not delay with this process: waterproof the pool before you start using it.

Types of waterproofing

If the pool is located inside the structure, then only internal waterproofing is performed, protecting the surface of the font from the negative effects of water penetrating through (possibly) poor-quality materials or cracks. And, if the pool is located outside, then in addition to the internal one, it is necessary to perform external waterproofing, which protects the bowl of the concrete pool from groundwater and all the aggressive elements contained in them.

That is, the purpose of waterproofing is to make concrete waterproof. The strength and durability of the concrete pool as a whole depends on how well and correctly it is performed.

Important! If during the operation of the pool there were cracks of more than 4 mm, then it is unlikely that any waterproofing of the pool will solve this problem. In this case, more "drastic" measures will have to be taken.

Classification of materials for waterproofing

By Application

All used waterproofing materials are divided into two main groups:

• bituminous;
• polymeric.

Insulating bitumen is a material obtained by blowing tar with hot air. For your information: tar is obtained by heating the last fraction formed during oil refining in a vacuum to a very high temperature (exceeding 400 degrees). The main feature of insulating bitumen (tar-like substance) is that it does not dissolve in water. After its application to the surface, it forms a durable and waterproof coating that does not corrode.

Practice shows that the use of such waterproofing can significantly increase the life of the pool and guarantee its long-term operation even in conditions of constant contact with groundwater. Roll and coating materials (mastics) are made from bitumen.

Polymeric waterproofing includes compositions based on polyurethane. After this material is applied to the surface, it interacts with air and is converted into a polymer film that protects against moisture. Polymer waterproofing is a universal coating and has a number of advantages:

• good elasticity;
• durability (service life more than 15 years);
• has excellent adhesion to materials such as ceramic tiles, concrete, glass and brick;
• resistant to temperature extremes;
• easy to apply (due to the fact that the composition is a liquid or semi-liquid substance).

Polymer insulation can be coated and sprayed. In the construction market, it is presented in the form of mastics and sealants. With the help of mastic, you can cover rather uneven and hard-to-reach surfaces with a protective layer. Sealant is a more viscous "representative" of polymer waterproofing, which can be easily applied to the surface of any geometric shape (for example, it can be used to isolate joints and seams). Liquid rubber also belongs to the category of polymer waterproofing.

According to the application method

According to the method of application, materials are divided into:

• coating;
• sprayed;
• rolled.

Coating compositions (penetrating impregnations, bituminous and polymeric mastics) are used to create a seamless monolithic layer. Most often, one- or two-component cement-polymer waterproofing is made, using which it is possible to carefully seal the pores and small cracks formed in concrete. Coating materials, which have a relatively low cost, are able to provide high-quality protection of the font with minimal labor costs: after all, you can apply several layers of mastic with a brush or spatula on your own.

Roll materials (roofing material, film membrane, PVC film) are used to equip the pool protection both from the outside and from the inside. True, using such materials, you will not be able to avoid the presence of seams in the insulation.

Advice! Rolled materials are laid in two layers to overlap the seams.

Criteria for evaluating waterproofing material

Pool waterproofing can be done using a variety of materials, but not all of them are equally effective. Requirements for waterproofing material:

• moisture resistance;
• resistance to deformations and other mechanical influences;
• immunity to temperature extremes;
• good adhesion to other materials;
• elasticity.

External waterproofing technology

Before proceeding with the arrangement of the protection of the font bowl from the inside, external waterproofing of the pool is performed:

• if the groundwater level is higher than the bottom plate, then we construct a drainage system around the font;
• we perform a concrete screed of the base of the pool;
• lay out the prepared roll material on the ground (according to previously made measurements);
• we connect the seams;
• we lay the external waterproofing, performing it with a large margin at the edges, so that later it can be brought to the walls of the pool and connected to the internal insulating layer of the bowl.

Important! Instead of rolled material, penetrating compounds can be used as external waterproofing, for example, mastics, with which we fill the smallest pores and cracks.

Technology for arranging internal waterproofing

The internal waterproofing of the pool is an important stage in the construction of the entire facility. The technology for applying all kinds of coating materials is quite simple:

• after pouring the bowl (by the way, in order to increase the waterproofing properties of concrete, we add plasticizers and special additives to it), leave it for final drying;
• small cracks and other defects are sealed with resin or sealant;
• we equip the font base screed with a self-leveling mortar;
• we carry out plastering works;
• we clean the surface of the bowl to make it rough (this is necessary for better adhesion of the protective coating to concrete);
• remove dust and debris; degrease the surface;
• we prime the inner surface of the pool bowl with a special composition;
• let the primer dry (drying time is indicated on the package);
• prepare the coating composition according to the instructions;
• we apply waterproofing in two or three layers, generously brushing the seams, small cracks, gaps and junctions of the pool surface planes with a brush (each subsequent layer is applied only after the previous one has dried);
• after the waterproofing layer is completely dry, we check the pool for leaks;
• we carry out facing works.

On a note! Remember: "the miser pays twice", so it's better to buy expensive coating materials (they are more effective), and in combination with fiberglass mesh they become more durable and elastic.

The most popular waterproofing materials

Liquid rubber

Liquid rubber is a bitumen-polymer mastic that has good waterproofing properties and combines the advantages of coating materials and rolls. It is applied in several layers: as a result, we get a pleasant to the touch, dense and durable seamless coating.

Liquid rubber is a versatile material in the sense that it can act both as a topcoat, that is, without subsequent decoration (just buy a colored material), and as a base for tiles or mosaics.

Liquid glass

An aqueous alkaline solution of sodium or potassium silicates is nothing more than water glass, which is also known in the trade as silicate glue. Liquid glass in combination with a cement-sand mortar creates a durable waterproofing coating. The advantages of silicate glue include the fact that it is relatively inexpensive, and the disadvantages are that this material quickly hardens after kneading (within 5 minutes) and is short-lived.

PVC film

PVC film as a waterproofing is the most popular material. With all its advantages, one should not forget about the disadvantages: expensive installation (as one cannot do without the participation of professionals) and the material is susceptible to mechanical stress.

So, the abundance of waterproofing materials will allow you to produce high-quality protection for your pool, and it will delight you for many years.

The pool is a highlight of any personal plot. If you decide to arrange it yourself or restore an existing structure, then you need to familiarize yourself with how and with what materials the pool is made from the inside. The durability of the use of this structure depends on how well and what material this work will be performed.

Materials for pools are selected taking into account the climatic conditions of the area in which they will be operated. There are several main commonly used waterproofing materials that are used for external and internal insulation:

•  Polyvinylchloride or PVC film
•  Cement-polymer penetrating
•  Liquid glass or silicates of sodium and potassium
•  Coating waterproofing polymer mastic
•  Liquid rubber
•  Pasting bituminous rolled waterproofing

PVC film or membrane is the most progressive type of internal. It combines not only protection against leaks, but at the same time it is a decorative pool cover. It is used in combination with a geotextile substrate.

Such a substrate will smooth out all the small irregularities of the bottom and walls, making them soft and comfortable. The color of PVC film can be very different. Marble and mosaic are especially popular.

Cement-polymer penetrating pools are used for processing the outer and inner walls of pools. The composition of the mixture includes cement, sand and polymer additives. Thanks to polymers, the solution, getting into the smallest pores and microcracks of concrete, reliably clogs them.

Penetrating is diluted with water to a state of sour cream and applied with a brush or roller to the concrete walls of the pool. Professionals use compressors and sprayers to apply.

Liquid glass is added during the manufacture of concrete to improve its resistance to water. Sodium and potassium silicates are applied to the outer and inner walls of a concrete structure. These are aqueous solutions and it is convenient to apply them with a household sprayer for spraying bushes and fruit trees.

It is important to know! It is necessary to use penetrating waterproofing and liquid glass in combination with other types of external and internal insulation of concrete structures.

Coating with polymer mastic is used for interior work in the pool. Modern industry produces mastics in a wide range of colors. They are easy to apply on the surface of the walls and floor of the pool.

Cover the inner surface using a brush or roller. In the event that the mastic is thick, it can be diluted with a special solvent. After applying to the floor of the pool, a layer of mastic is rolled with a spiked roller - doctor blade. This is necessary to remove small air bubbles through which water can seep.

Waterproofing of pools with liquid rubber is used for internal protection against leaks, as well as for external protection against groundwater. It can be applied with a regular brush or a special sprayer with an attached compressor.

Adhesive waterproofing is used only for external protection of the pool bowl from groundwater. It is applied to walls as additional protection after concrete has been treated with penetrating insulation or liquid glass. Pasting is carried out using a gas burner, which heats up the bitumen-based roll material and presses it tightly against the walls.

It is important to know! When using rolled adhesive waterproofing, the formation of air bubbles under the coating is unacceptable.

The procedure for carrying out waterproofing work

The pool waterproofing technology provides for external and internal work. If water protection of an old structure is carried out, then it is necessary to remove the soil along the perimeter of the walls to the very pillow on which concrete blocks or monolithic walls rest.

After that, the walls are cleaned of soil residues and delaminations of old concrete. The seams of the block walls are embroidered to a depth of 3-5 cm with a perforator. After that, they are sealed with a thick solution of penetrating waterproofing of the Penetron type and smoothed with a trowel.

The outer walls are moistened with water and after 10-15 minutes a liquid solution of penetrating insulation is sprayed onto the walls. If the composition is applied with a brush or roller, then its consistency should be like sour cream. After 24 hours, when the first layer has polymerized, a second layer is applied.

Important to remember! The layer thickness must be at least 2 mm.

After applying the penetrating waterproofing, liquid rubber or bituminous pasting insulation can be applied to the exterior walls.

When the outdoor work is completed, the soil is backfilled. It is recommended to perform it not with dump soil, but with clay. At the same time, I carefully tamp it down. Now the waterproofing of the pool bowl is being carried out.

The surface of the walls must be plastered and carefully leveled. The floor of the pool is leveled with a concrete screed with the addition of liquid glass. The floor surface is poured with a self-leveling waterproofing cement-polymer mixture.

The surface of the walls is treated with penetrating waterproofing. Particular attention should be paid to the following parts:

•  Pipe entry holes
•  Wall and floor connections
•  Corners of the pool walls

After polymerization of the penetrating waterproofing, a colored polymer mastic is applied to the walls and floor of the pool. The mastic is applied in 2-3 layers with an interval of 6-7 hours. After 24 hours, the pool can be filled with water and checked for leaks.
