For a comfortable and enjoyable vacation, summer residents and homeowners arrange on their site pools, which in our time have become fashion trend. Especially often such tanks make on your own to cut costs. At a certain stage work, which should be approached responsibly, as from This depends on both the service life of the tank and its reliability. DIY waterproofing of the pool correctly and efficiently. But how to do that? What materials to apply and what is the essence of the work? About this you can find out below.

Waterproofing – why is it?

Why waterproofingWhy do i need waterproofing

Agree that not all are specialists in this area. It is often said about the importance of waterproofing, and its the correct device. But why is she? What will its use give?

As you know, waterproofing is a protective layer for any building structure (in this case, the pool), protecting it from penetration and the negative effects of water. Since the pool directly associated with this fluid, it is important that it does not penetrate material. Why? When moisture seeps into concrete, it will lead to its destruction, as a result, your pool will not last long, and then it will have to be repaired or completely refitted. it one of the most important stages of work. It is important to note two types pool waterproofing:

  1. Internal waterproofing.
  2. External waterproofing.

Internal waterproofingInner waterproofing

It is the internal waterproofing carried out in the bowl itself pool to protect material from water penetration. there is many different ways to do this, which we will talk about further.

External waterproofingExternal waterproofing

The essence of external or external waterproofing is to protect concrete from the penetration of moisture from the soil, by adding to it composition of plasticizing and mineral additives. It contributes increase water permeability and mechanical strength of the structure. Another option is to install special profiles from an expanding rubber. It is worth noting and penetrating compounds that are applied to concrete for external waterproofing. These are special mastics that easy to apply on your own.

Materials for waterproofing works

The good news is that the range of materials for such work wide enough, and you will have something to work with. Selection of such materials depends on many factors, among which your desire, product price, etc., however, it is important to consider the terrain and climate in your region, as well as the type of finished pool.

PVC film for poolsPVC film for pools

The main and most common materials for waterproofing are:

  • PVC film;
  • penetrating waterproofing;
  • liquid glass;
  • coating waterproofing;
  • liquid rubber;
  • various materials on a bitumen basis (the option was effective earlier, when the above materials were not yet, but now rarely used).

The technology of waterproofing the pool from the inside

The scheme of applying waterproofingApplication Scheme waterproofing

Consider all the work in stages. Thanks to this instruction, you You can waterproof yourself on the inside.

Plaster the bowlPlaster the bowl

So you should:

  1. Clean the concrete base of all debris and dust.
  2. To expand all cracks and seams and process them with special means for sealing joints. All joints must be followed. glue with sealing tapes.
  3. Level the entire surface by plastering the bowl. At treat the walls with special compounds for pools, which are resistant to moisture, and at the bottom of the bowl make a screed from self-leveling cement mixture.
  4. PrimerPrimer Primer dry surface primer. You can apply it with a brush or roller. By after 3-4 hours the surface will be ready and you can apply following layers.
  5. Now dilute the dry mixture of penetrating waterproofing with water, to get a thin consistency, like sour cream. It’s better use the instructions. Exactly the ratio indicated by manufacturers, is optimal.
  6. Using a wide brush, apply the solution to the base, which already prepared in advance by you. Handle especially carefully places for entering communications, seams between the walls and the bottom of the pool, and also the seams formed during concreting, and the places where cracks.
  7. It is worth noting that when processing the pool waterproofing compounds, you need to apply them comprehensively: first thing penetrating solution, followed by coating. As soon as you apply penetrating solution, the entire surface must be treated with hydrochloric acid 4-5%, then rinse with water. After gone half an hour, again treat the surface with a solution of 4-5% soda ash. And only after all the procedures can be applied grease mastic.
  8. As soon as the entire surface of the pool is processed waterproofing material, warn everyone not to stepped on her. You can’t walk on them, moreover, for 3 days, the temperature should not fall below 0 ° C. That’s why such work should be carried out in summer.
  9. To avoid cracking and peeling of the material, during 3 days the entire surface needs to be moisturized. Those places that will be under water pressure, you need to moisturize for at least 10 days. For humidification, a water sprayer is well suited, and the concrete itself the surface of the pool at this time must be covered with polyethylene film.
  10. Finally, after completing all work, the pool bowl should check for leaks. Water is collected in the pool and aged there 10 days. If no leak is detected, all water is drained, the bottom is cleaned. from debris and allow to dry.
  11. In conclusion, facing works are carried out. Basin bowl tile or mosaic.

Liquid rubber

Liquid rubberLiquid rubber

Liquid rubber is called bitumen-polymer mastic. She’s well adheres to the surface and has good waterproofing quality. It must be sprayed onto the surface in several layers. For this job will need a special compressor or brush (using roller or brush, will have to work much longer).

The advantage of liquid rubber is that it combines advantages of liquid waterproofing and PVC membranes. In the end, you get continuous coating that adheres well to the surface without any or seams. Such a coating is pleasant to the touch, like a PVC membrane, and It has excellent density and durability. Material may protrude as a base for the subsequent decorative layer, and also serve and finish coating itself. To do this, just buy a color material and is not spent on decoration.

Application of liquid waterproofingApplying liquid waterproofing

How to make waterproofing liquid rubber? Immediately before by applying the composition, the entire surface of the pool bowl should be leveled and treated with a compound that will degrade it. Then with a special compressor or brush (if it’s about independent work) the rubber must be applied to the surface so so that the composition evenly covers it.

Using liquid glass

Liquid glassLiquid glass

Liquid glass is a solution consisting of potassium silicates. or sodium. This option of waterproofing can be performed at the stage pool construction. Liquid glass is added to the concrete itself, in the ratio of 1 liter of glass per 100 liters of finished concrete. Thanks to this he becomes more durable, resistant to mechanical damage and will last longer. And most importantly for you, liquid glass will allow concrete to reduce the ability to absorb moisture.

When your pool is already built, liquid glass can be applied directly onto concrete. There are special coating products, using which you can achieve good waterproofing, and also protect concrete from mold and mildew. In addition, coverage on for 5 years it will protect the pool from the effects of temperature, corrosion and ultraviolet. It is worth noting that perform such waterproofing yourself will be easy. The price of glass is not so and high, and material consumption will be small.

Application of liquid glassApplying liquid glass

The work is simple, all you need is:

  1. Prepare the surface by removing all dust, dirt and grease stains. If the concrete is smooth, it should be cleaned to give roughness, then the glass clings better, penetrating deeper.
  2. Prepare water glass based on instructions on packaging.
  3. Apply the composition evenly to the surface. As the glass will dry, start applying the second layer. Use a wide brush or roller.
  4. After drying, everything is ready for subsequent decorative layer.

Using PVC films

Waterproofing with PVC foilPVC waterproofing film

Do not forget about the most popular type of waterproofing – PVC film. This is a reliable and progressive material, which is increasingly more often used in the construction of pools. Notable is that the film has two roles: waterproofing and decorative layer. This will save you money. There is a mass in the market different types of films that are durable, color and pattern (mosaic, marble, etc.). In addition, the film is different resistant to mechanical damage and withstands well exposure to ultraviolet rays.

The work of laying PVC film is similar to other processes. The first thing you need to do is prepare the foundation, remove garbage etc. Then fixing tapes or corners are fixed, which will attach the film.

It is desirable to lay the film on a special material – geotextiles, which will extend the life of the film. Thanks to him, the material will not be constantly rub on concrete.

Finally, you need to spread the PVC film and weld individual its parts with a special tool. It is simple, fast, reliable. and an economical way to waterproof your pool.

All these methods are good in their own way, you just have to choose one the option that suits you best, study the technology and bring everything to life. Pool waterproofing is an important part of work by its device, which should be approached responsibly.
