Waterproofing of a concrete pool is one of the most important stages in its arrangement. High-quality waterproofing material is able to protect concrete from various destructive substances, such as moisture, salt, chlorine, etc. Also, the material prevents the formation of fungus on the surface, due to which its appearance deteriorates and an unpleasant smell of dampness may appear. In addition, properly selected waterproofing prevents the outflow of water from the pool due to the formed shrinkage cracks in the concrete bowl or due to the influence of various external factors, such as the influence of underwater waters.
As a conclusion, using high-quality waterproofing you significantly extend the service life of your concrete pool.
Waterproofing of the pool
Pool waterproofing cannot be called the use of a single material, since this is an integrated approach in which it is necessary to study all possible changes in the structure of the earth, destructive factors, shrinkage, and only then determine the type of waterproofing for the method of application, resistance to positive or negative water pressure, elasticity, strength, and so on.
Since a filled concrete pool is a fairly heavy structure, it is necessary to take into account shrinkage and the possibility of cracks on the concrete during it. Therefore, it is recommended to use a high-quality elastic material for waterproofing, which will not be covered with cracks during shrinkage.
How not to make a mistake with the choice of material, we will discuss below.
What external factors affect the pool outside?
Very often, when creating a waterproofing layer on the pool bowl, they do not think about serious consequences, the cause of which may be precisely external factors.
Among them:
- displacement of soils;
- the presence of groundwater close to the basin bowl and, as a consequence, the effect of negative water pressure on concrete (i.e., outside);
- frost heaving (the so-called phenomenon in which, due to the freezing of the soil, its volume increases).
What factors affect the pool from the inside?
Among the internal factors affecting the pool are:
- the pool water itself, which creates a positive water pressure on the surface of the pool bowl;
- mechanical damage during operation;
- poorly made pool lining layer.
Based on the above information, we conclude that it is necessary to waterproofing the pool with an elastic material for high-strength waterproofing, which will be resistant to both types of water pressure: positive and negative.
An excellent example is the Teknomer 200 EX-Blue, which has all the necessary technical characteristics. By the way, the material is produced in a beautiful saturated blue color, so it can serve not only as a waterproofing material, but also as a cladding.
