Waterproofing of pools - materials and work performance, protection options and methods

Waterproofing of pools

Pools can rightly be attributed to the objectsincreased complexity. As hydraulic structures, created by water, they experience significant load. The water that fills the pool, has an impact on the materials used, its skeleton, and eventually destroys the pool structure in general. That is why the pool waterproofing is one of the most important stages of their devices.

It is noteworthy that no differences in technologypool waterproofing waterproofing from other rooms, characterized by an increased level of humidity, no. However, we must consider the fact that the materials used for these activities, vary widely in composition and performance characteristics. Thus, the pool has a special primer formulated to apply it is much thicker than normal.

Quite important is the question of operationalproperties of the materials used for the pool device. Among the designs particularly popular purchased reinforced concrete, brick and solid versions. For waterproofing of buildings used frequently enough elastic materials forming the coating repels water and prevents the appearance of cracks in the walls of the pool. But along with them are widely used and cement-polymer compositions.

Waterproofing of swimming pools - construction materials protection from the damaging effects of water

It is no secret that the market of waterproofing materialsconstantly offers consumers a wide variety of new products, both domestic and foreign manufacturers. It is therefore recommended to study carefully this segment before you stop your choice on any particular material for waterproofing swimming pools.

Types of pool waterproofing

To date, the pool waterproofing isIt is both internal and external. The latter is designed to ensure the protection of the hydraulic structure of the groundwater. Internal insulation to prevent a negative impact on water bowl basin and protects against leaks.

It is worth mentioning that the previously used materialswaterproofing basins, particularly a mastic, roofing material, various polyvinylchloride film differed poor adhesion. Moreover, providing enough high demands on the insulated surface, for example, do not allow moisture base.

As for the outer insulation, manymaterials, which have become traditional for the protection of swimming pools from the negative effects of moisture, working at the gap, resulting in the need to install additional retaining walls. This in turn leads to an undesirable increase of labor and materials costs. It is therefore less expensive materials are used on the outside to protect the pool from the ground water. However, the higher the level of ground water, the greater the need for good quality waterproof outdoor pool. The fact that the ground water penetrated into the pores of the concrete, and can ruin the entire inner valve waterproofing, resulting in deformation of the entire structure.

Exterior waterproofing

Exterior waterproofing of pools is necessary to prevent the impact of groundwater

Internal waterproofing designed to protectthe whole structure pool from the damaging effects of corrosion. In addition, this type of insulation prevents flaking plaster applied that leads to the preservation of the strength of the pool and the sealing of his bowl. The fact that the waterproofing of the pool - it is one of the key devices of hydraulic structure. For any internal waterproofing the pool presented a number of mandatory requirements:

  • Good water resistance;
  • The elasticity of the insulating layer;
  • The subtlety of waterproofing;
  • Resistance to the disclosure of cracks up to 3 mm;
  • The high degree of adhesion;
  • The ability to withstand hydrostatic not only, but also dynamic loads;
  • Inhibition of propagation of various fungi and bacteria;
  • Environmentally friendly.

Other methods of protection against water

Technology implementation waterproofing worksmostly similar, and their main differences are determined waterproofing material used, each coating has its own characteristics.

Undoubtedly, immediately before applicationthe insulating layer is necessary to hold a series of preparatory work. The surface on which is applied waterproofing material, should be as smooth, on it there should be no cracks, chips and other defects. In addition, you should be completely absent any dirt or other coatings residues. Most often such cleaning the insulated surface is carried out by sandblasting.

Today waterproofing basin with his hands can be accomplished by a variety of compositions. These include:

  • Solutions of mineral acids. Their main purpose is to reveal the concrete long enough for the deepest penetration of the waterproofing compound.
  • Polymerized impregnation. They penetrate into the concrete, are polymerized to form the plastic. This type of impregnation strengthens bowl basin, made of concrete, and create an excellent basis for a layer of plaster.
  • Additives to the solutions. Among them accepted to various grouting and adhesives that improve waterproofing properties of concrete and other compositions.

With specific regard to materialswaterproofing swimming pools, the manufacturers are presented in a rather wide range. This membrane may be polymeric, liquid rubber penetrating cement compositions, water glass and others. Each of these materials requires a certain technology waterproofing operations.

Materials based on bitumen

This type of waterproofing materials receivedwidespread more than 50 years ago, which allows for the right to call it traditional. It was in the 60s of the last century on the market of insulation materials appeared bituminous mastics, roofing material and fusing roll materials.

Bituminous materials for waterproofing

Today, these materials are not usedbowls for waterproofing pools, as characterized by poor adhesion with the adhesive compositions, which are used for the installation of the pool liner.

Penetrating waterproofing for pools

The basis of this type of sealing ispenetration of insulating material in the pores of the concrete where it polymerizes and clog them reliably. composition Penetration depth can reach 0.5 m. Particular ease of use of this material is the possibility of applying it on the inside of the insulated structure. Penetrating waterproofing enhances the degree of frost resistance of concrete and prevents mold and mildew.

Penetrating waterproofing

Action penetrating pool waterproofing

It is worth noting that the waterproofing of swimming poolsown hands with the help of penetrating compositions has some disadvantages. So, there is no possibility of isolation places concrete compounds and elements of water supply equipment, sealing of cracks occurring in a layer of plaster.

Isolation on the basis of cement

Waterproofing materials, having at the basecement-sand mixture, characterized bicomponent since their structure modified polymers are added. As a rule, such a waterproofing layer has a thickness of 2-5 cm. The application of insulation is achieved in stages.

Waterproofing materials, cement-baseThey have excellent performance characteristics. They are ideal for outdoor and indoor insulation home pools. A high degree of adhesion to a variety of surfaces, easy to perceive the dynamic and static load.

Such waterproofing materials, above allalia, differ good water vapor permeability, which allows you to not worry about the problem of the emergence of bubbles and blisters. Indicators of reliability and durability of these materials are also quite high. The apparent advantage of the insulation, cement-base is the convenience and ease of application. Thus, cement waterproofing can be applied even on wet surfaces.

However, it should be noted some shortcomingsthese waterproofing materials. The biggest disadvantage is the low degree of elasticity, which leads to low efficiency of the material at varying temperatures, in areas of stress concentration. The solution to this problem would be silicone or elastic sealants. Seams formed by these compounds would be unloading "zones."

Liquid glass - effective material

Currently particularly popular purchasedwaterproofing pools liquid crystal, which is a conventional aqueous solution of sodium silicate. This solution allows to increase the operating period of the pool several times, in addition, it compares favorably with antiseptic properties.

Liquid glass for waterproofing the pool

Liquid glass filled all the pores and cracks in theconcrete that protects it from corrosion and damaging effects of moisture and air. Liquid glass has a high adhesion to the applied surface of the refractory. It can be used in a pool waterproofing impregnation, additives and supplements.

Waterproofing of swimming pools using membranes

The membrane for waterproofing pools

Experts note that the membrane system,used for the isolation of hydraulic structures, such as swimming pools, excellent work on the compression and tension, allowing them to easily withstand the high loads on the break. However, work with membranes requires a special welding machine or dryer for welding seams. As a rule, this work is performed by qualified personnel, as poor quality welding membrane disrupt the integrity of the waterproofing layer. Thus, the presence of small holes 1-2 mm would cause all the water that fills the pool, may be a waterproofing coating.

Thus, there is todaymany different compositions and materials that are to some extent used for high-quality waterproofing swimming pools, both indoor and outdoor. Solving the problem of how to make waterproofing the pool, you need to carefully study the relevant segment of the market of insulation materials, to consider their own preferences, the pool size, the material for his own cup, financial opportunities. Given these nuances will perform high-quality waterproofing, which will ensure the durability of any pool.
