Concrete swimming pool is one of the most popular types of swimming pools in the world today. Firstly, it has a long service life, and secondly it is not so expensive to make. But such a pool requires proper protection from the influence of water, which a properly selected waterproofing material will cope with, which we will tell you about in our article.
What kind of waterproofing is suitable for swimming pools?
It is quite logical that not every waterproofing material is suitable for finishing pools, since such a design requires a special approach.
Below we will describe what features the material for waterproofing a concrete pool should have.
Elasticity
Everyone says that after buying an apartment in a new building, it is better not to do repairs for the first six months, a year, or even two, since shrinkage should occur, due to which the cladding materials can either crack, or fall off, or come off, and so on.
The same thing can happen with a swimming pool. Imagine that a concrete bowl is filled with several tons of water for the first time, what happens? Naturally, shrinkage. But a concrete pool cannot be filled first, wait for shrinkage, then drain the water, and only then cover with all the necessary materials, including cladding. Therefore, it is necessary to apply elastic waterproofing materials to the concrete bowls of swimming pools, which are not afraid of shrinkage, and therefore are not covered with cracks.
By the way, this also applies to repairs in houses: choosing the right materials, there is no need to wait up to 2 years until the structure shrinks.
Resistance to both types of water pressure
A concrete pool is a structure whose walls can succumb to water pressure from two sides: internal and external.
From the inside, the water in the pool itself presses on the walls of the concrete bowl, and from the outside, the water that passes underground. And if there were no such people nearby when creating the project, then this does not guarantee that they will not appear in a year, two or ten. Therefore, experts always recommend choosing waterproofing that will protect concrete bowls from both types of water pressure.

Wear resistance
A swimming pool is a structure that is in constant contact with water, and also lends itself to strong temperature changes, since most often concrete pools are built in an open space.
Therefore, in addition to moisture, high-quality waterproofing material should not be afraid of frosts, hot weather, various precipitation and other possible weather changes.
In addition, swimming pools are usually built once and for all, so all materials need to be selected high-quality, durable and, of course, safe for humans.
