What is a masonry swimming pool?

Before anything else, let's understand what a masonry swimming pool is so we can delve deeper into the subject.

Basically, the masonry swimming pool is a swimming pool model which is built from conventional masonry, that is, through bricks or blocks which are joined together by mortar. It is the most used way to build swimming pools and the most consolidated in the civil construction market. However, it is possible to build a pool in other ways which are as efficient as masonry.

All masonry construction offers several advantages, mainly in terms of strength and durability. However, there are also downsides that should be considered when choosing which type of construction best suits your project. Therefore, I will present the advantages and disadvantages of using masonry to build pools and then you can decide which one to use. This you will find in the next topic.

What are its advantages? And its disadvantages?

Now it's time to understand the advantages and disadvantages of using masonry pools. Let's go?

The main advantage that the masonry pool provides is that it allows the most varied types and formats, and can be designed according to the customer's taste. First of all, let's look at the advantages:

  • Versatility: using masonry as a way to build your pool gives you the freedom to choose different shapes, sizes and types of lining. This makes it possible to build a personalised pool that matches your architectural design.
  • Resistance: masonry offers an unparalleled resistance for the pool, presenting a long useful life. For this to be guaranteed, all its execution needs to be well done, as well as periodic maintenance.
  • Lining options: masonry pools are excellent, as they give you the freedom to choose several types of lining.
  • Cost-benefit: yes, the costs are higher when compared to other types of pools, but the benefits are worth the investment.

With regard to the disadvantages, we can cite:

  • Maintenance: because of the types of lining that can be used in masonry pools, there is a greater accumulation of dirt, which requires more frequent cleaning. Maintenance, in case of leaks, is more difficult. 
  • Cost: considering only the value, masonry pools are more expensive, but one should also take into account their benefits.
  • Delivery time: because it is more laborious, the construction time for this type of pool is not very fast, prolonging the delivery time.

As any option in the market presents positive and negative points, with the masonry pools is no different. Therefore, evaluate all the characteristics of masonry pools to understand if it is a good option for your work.

How to make a masonry swimming pool?

Building a masonry swimming pool is not as simple as it seems, as it requires work. Simply put, the process is divided into steps, which are:

  1. Define the location, shape and depth;
  2. Analyse the soil characteristics;
  3. Laying the foundation and the structure;
  4. Waterproofing the pool;
  5. Apply the coating.

Of course, each stage must follow all the recommendations of the technical standards (NBR 10339) as well as having a professional team with experience in performing this type of service. Therefore, study well how to carry out each stage in the correct way. Failures in each of these steps can compromise the entire structure of the pool. I can assure you that it is not worth skipping steps or not performing them the right way.

What are the linings for a masonry swimming pool?

One of the great advantages of masonry pools is that they allow the use of various types of linings, which gives personality to the projects. Thus, it is possible to make the pool match the entire decoration of the house.

Among the most commonly used coverings in masonry pools, we have: tiles, glass tessellations, natural stones, vinyl lining, ceramic and porcelain tiles.

It is possible to find pool linings of various colours and models, but it is more common to use green and blue, although there are modern projects with other colour sets. The type of lining will depend on the style of decoration, maintenance and available budget.

As for the lining of the edges of the pools, there are many options. But, it is interesting to use anti-sliding floors that don't heat up too much. Natural stones are great allies in this sense. However, it is essential to hydrofuge them with BlokSeal so that they do not suffer with the action of water and remain preserved for many years.

How to waterproof masonry swimming pools?

Waterproofing masonry pools is a very important step that should be done the right way to avoid future problems. We can summarize by saying that pools should be waterproofed both from the inside, which is exposed to water from within the pool, and from the outside, where the structure is subject to the action of humidity from the ground. Therefore, as in both cases water exerts positive pressure on the structure, you need to use a specific product for positive hydrostatic pressure.

The best product for this purpose is Blok ST, a waterproofing agent capable of fighting humidity, preventing water from penetrating the surface and causing infiltrations that can affect the entire structure, causing major inconvenience. Thus, it is perfect for waterproofing swimming pools, leaving them protected against the action of water and its disastrous consequences.

How should pools be cleaned and maintained?

As we have already mentioned, masonry pools require more maintenance and cleaning.

Because of the grout, there may be more accumulation of dirt, which requires more frequent cleaning of the pool. However, it is important to have professional help to carry out this type of service.

As for maintenance, it should be done periodically or if there is any sign of a problem, a specialized professional should be hired to correct it so that it doesn't become something much bigger and more complicated to fix. If done the right way and periodically, masonry pools have much better durability than other types of pools.


Did you like to understand more about masonry pools? They are resistant and last for many years, but require care such as cleaning and maintenance that must be taken seriously. Therefore, they offer several types of benefits and can be an interesting option for you to use in your construction site.

If you choose masonry as the way to build your pool, do not forget to use Blok ST so that it is protected against the harmful action of water and requires little maintenance over the years. Talk to the Blok team to understand how to waterproof your pool the right way. See you next time!
