When you want to make your own pool or work with local craftsmen, you have to look for the simplest construction solutions. One of them is undoubtedly to make a reinforced concrete block pool.
What is meant by renforce concrete blocks?
We are talking here about a construction with blocks filled with concrete and not building blocks; the latter are only used on small skimmer pools and do not allow all types of lining. You can find more information about pool lining in this post.
These blocks are made of factory-moulded concrete; they differ from cinder blocks in that they have holes in the base and are dry-assembled. Each block has 1 or 2 cells to allow the passage of the irons essential to the construction of the pool walls. The blocks are then filled with concrete delivered by truck or made on site with the concrete mixer; it must be fluid enough to fill the block cells correctly and to coat the reinforcement well. Its structure is similar to that of poured concrete but does not require any expensive equipment for its implementation: no metal or wooden panels and no concrete spraying machine either.
Why build your infinity pool with these kind of blocks?
This method of construction has many advantages but also some disadvantages.
- The implementation is very simple for a mason or an experienced handyman in masonry. Of course, don’t go on this adventure alone if you have no experience.
- Any pool project can be built with this system. It is possible to build an infinity pool with concrete blocks.
- Any pool lining is allowed: from liner to tile to fiberglass reinforced polyester.
- Any shape is possible.
- It is easy to cut the blocks in the places previewed for the parts to be sealed.
- The cost of construction is cheaper than any other formwork system.
- The blocks are relatively heavy to handle.
- Before tiling, it is imperative to apply a waterproofing plaster.
An example of an infinity concrete blocks pool
A year ago a couple contacted us for help. It was a large swimming pool located in Spain that they had decided to build themselves.
Having at their disposal 2 masons and a plumber, they did not wish to call upon a swimming pool specialist. This allowed them to control the work and the budget, buy the material themselves to obtain discounts from suppliers and manage the progress of their work. The only problem was that neither they nor the workers had any experience in pool construction.
They therefore sent us to carry out the plans, but also to remotely supervise the construction site. It was, indeed, out of question to make their budget explode with regular and expensive travel expenses.
If you too want to start building your own overflow pool and want to know every step of the design process, we advise you to read this post.
Characteristics of the project
- 16 meters long and 6 meters wide and 1.30 m to 2.60 m deep cascading overflow pool. Children’s pool with overflow of 4 metres by 2 metres.
- Pool build in 27cm wide hollow concrete blocks.
- Technical room and buffer tank built against the pool.
- Filtration of ±40m2/h (2 groups of filtration) with salt sterilization.
- Pool lining made with glass-fibre reinforced polyester
Steps before the construction site
For this swimming pool, we proceeded as usual; from the photos of the land and the indications of the owner, we made the plans necessary for the execution of this project. We present them to you in the gallery to allow you to judge the scope of the project.
To allow them to build this pool alone, the hydraulic plans were not forgotten. They include both the external networks for the supply from the technical room to the pool and the installation of the technical room itself. The aim was to ensure that nothing was forgotten. Detailed sketches were often useful to explain what we expected, for example, from the mason. As I recall, the owners had no notion of construction.
The progress of the construction site
These photos, plus many others of course, allowed us to follow the progress of the construction site from a distance. We have, very often, been able to hold site meetings via Skype and thus be able to check that our instructions were being followed or to help solve any unforeseen problems.
The result is up to the owners’ expectations. In addition to the satisfaction of having been able to complete this project that was really close to their hearts, the savings were significant.
And you, when are you going to get started?
Blogs of people who have built their own swimming pools are flourishing on the internet; it’s very interesting but they only describe the stages of the work. If you really want to build your concrete block pool, you need a little more than these videos. First of all, you need a ground plan adapted to your desires as well as to the configuration of the land and the house. Then, thanks to a detailed plan of the pipes and the technical room, the filtration is installed according to the rules of the art. Finally, the list of equipment and our advice will help you choose the equipment you really need.
