The concrete structure of a pool must contain all the water. It must also withstand without breaking the large pressure loads there are. These charges are caused by the thrust made by the weight of the earth on the outside and the importance of the water on the inside. Every time we empty the pool. We are removing part of that push and depending on our structure, serious problems may or may not be caused. In this article, we will present how to build a concrete swimming pool.
How to build a concrete swimming pool?
Once you know some advantages of building a concrete pool, it is time to show you how to make a concrete pool, but not before telling you it is essential to apply for the corresponding municipal building licenses. To do this, you must go to your town hall to inform you of all the requirements that you must meet to build a swimming pool in your home. Keep reading: AMENITIES FOR THE POOL
This step is significant, and many people make it visible, which makes later there are legal problems that are easily avoided by carrying out the procedures according to the regulations of your locality. In some cases, pool installation companies can help you deal with this matter.
Choose the location and design
Before starting with the construction of the pool itself, it is essential that you design it. It takes into account the shape you would like it to have, its size, depth, color and also the filtration system that you want it to count.
At the same time that you design your ideal swimming pool, you should consider which place is the most suitable for its placement, having to a value that there is a flat terrain with enough space. It is far from the trees to avoid that it is filled with leaves and that it has a good orientation to the sun. We would suggest you to hire professional services to get the job done perfectly. You can visit ADP Group in this regard as they offer all kind of construction related services.
Once you are clear about the place where you are going to place the pool and have it designed, it is time to begin to give shape to the place where it will be built, for which you must start digging the ground.
To know how to build a concrete pool it is advisable to mark the perimeter of the pool using wooden stakes and to use a string of thread also to cast plaster on the line so you can see the area where it will be located the pool. Once this is done, it will be time to remove all the earth using a backhoe, but not before making sure that where you will dig there is no type of drainpipe, light or water.
When you are doing the excavation, you should assess the depth you want to give your pool, taking into account that the floor of the pool will occupy some space. It happens with the wall, so you must take it into account when digging for getting a pool with the desired dimensions. When taking on a job like this, you are always going to have a lot of waste. Hiring a skip or a waste management company can always be a good proactive decision to look into before starting. Just google waste management followed by your area, such as waste management Solihull, to find local teams who can help.
Pool bottom construction
The next step to carry out the excavation is to proceed to flatten the land so it is uniform, being very important since it will be the bottom of the pool. In the same way, it will be necessary to fill and compact the soil if the land where the pool is to be located is not firm.
You can make compaction of the natural soil or use a gravel fill or some other type of aggregate of between 12 and 40 mm granulometry.
Once this is done, and with the compaction of the terrain, which can be done with a lance roller or similar. It is time to pour into the pool a small layer of cleaning concrete with a thickness of about 5 centimeters.
Placement of rods on floor and walls
The next step: The placement of rods in the form of a grid both on the floor and on the walls.
It is possible to make use of a mesh in the ground, making sure it is of a sufficient thickness (more than 8 mm) and a maximum hole of 20 x 20, being advisable to use enough iron so that the glass of the pool enjoys higher resistance.
Then the angles for the walls must be placed. The wire must join which to the mesh of the bottom of the pool.
Types of structures for swimming pools
There are two types of structures: concrete formwork and shotcrete concrete. The formwork structure must be built in two parts, first the floor and then the walls. With this, we leave a junction of the concrete of the soil with that of the walls, and that’s where the water can go. The gunite structure is constructed in one piece and without any joints.
The concrete and thickness
It must be of quality and well prepared. It is important that all processes and materials are adequate for the best result. Ideally, it should be supplied by a company specialized in concrete. We built pools with shotcrete of selected aggregates and H-400.
Thicker more years of life. Pools with 10-15 cm thick structures have lasted between 10 and 20 years. Structures of 20-30 cm thick come lasting between 20 and 30 years and 35-50 cm thick they last between 35 and 45 years. From that time, they suffer small fissures that eventually become cracks. Up to sizes of 5m x 10m we use thicknesses of 25cm on the floor and 22cm on walls.
The iron grid
It must reinforce the concrete of the structure. We work in swimming pools up to sizes of 5m x 10m with a double electro-welded mesh of 8 mm over the entire surface, reinforcements with 10 mm bars at all corners and walls every 50 cm. With this, we get a very resistant skeleton. For larger pools. We must use other thicknesses and reinforcements.
What is the best structure for swimming pools?
Both are optimal for the construction of swimming pools if they are done well from the first hour. The gunite structure has more bodily union when done at once, which together holds the forces better. The formwork structure has two bodies, walls and floor. These can move separately if they suffer the force necessary for it, which can deform more easily. A good thickness in the formwork avoids these problems.
Frequent problems in concrete structures for swimming pools
Loss of properties: The direct contact of the concrete with the external humidity makes it wet almost all its life. This causes of damage is hardness and bonding properties of the concrete. After this process, the cracks and cracks caused by the thrusts of the ground and the weight of the water begin to appear when removing and putting it on. The thicker structures endure more years than the beautiful fabrics without breaking for that very reason.
To solve these problems, what we do is add a hydrophobic additive to the concrete of the structure so that it does not absorb moisture, give concrete a minimum thickness of 27cm in the floor and 22cm in the walls to last many years standing and reinforce all the interior corners of the glass with half-round canes.Tags: concrete pool, swimming pool
