Overflow pools are an alternative to pool kits. But how do you choose the right overflow for your land? What pitfalls need to be avoided? How do you prepare your construction project? Find out in our guide.

What Types Of Infinity Pools Should Be Built?

No skimmers in this in-ground or semi-in-ground pool, only an overflow:
Infinity edge overflows are the oldest. On one or more sides of a main pool, a weir replaces the coping so that the water spills out. It then flows to a gutter below and then to the filtration system. If you have sloped ground, it is perfect, regardless of whether you have panoramic views.

Zero edge pools, with water at the same level as the terrace, are ideal for flat backyards, patios, etc. Water collected in the gutters surrounding the pool flows into a surge tank, from which the filtration pump draws the water for filtration.

Most of these in-ground pools are built from reinforced concrete (poured or shotcrete) or from formwork blocks.

 Aside from offering a remarkable visual effect, the overflow effect also ensures that the water is of high quality. However, choosing between an infinity pool and a deck level pool can be challenging. You may need the assistance of a pool designer to decide the right overflow.

What Are The Current Planning Regulations?

Similarly to traditional pools, French pool construction rules are based on the size and surface of the pool.

Mini pools of less than 10 m2 do not require formalities but must, of course, comply with subdivision rules and the PLU.

  • Owners of pools between 10 and 100 square meters must submit a declaration of works.
  • Concrete pools larger than 100 square meters require a building permit.
  • Generally, a pool cannot be located closer than three meters to a neighbor’s fence.
However, there are exceptions based on each municipality’s land use plan.
  • No authorization is required for the installation of above-ground pools less than three months per year, regardless of their size.
  • A building permit is required if the pool enclosure is higher than 1.80 meters.
  • There are some municipalities that prohibit the use of blue waterproofing materials (liner, reinforced membrane, polyester, mosaic, etc.).
  • Special rules apply to indoor pools and to pools built in safeguarded areas.

Experts can help

It is an exciting experience to build your own infinity pool. However, a professional’s assistance is essential for making the most of this opportunity.

Make a list of your skills

There are some tasks that can be performed by a do-it-yourselfer. It is easier to see this clearly when you have detailed plans.

Infinity pools are our thing

How To Conduct A Ground Study?

It is the purpose of a soil survey, also known as a geotechnical survey, to characterize the soil type. An engineer writes a report after taking geological samples from the subsoil to advise on the type of foundation, formwork, and reinforcement of an in-ground pool.

Therefore, these studies do not apply to above ground pools, and they are not mandatory, but highly recommended. It is possible for issues such as ground movement, rock, or cavities that are invisible on the surface to impact a pool’s strength and longevity. By adapting the construction method, these issues can be addressed.

This study must be provided by the seller of any building land, since 2020 in France (ELAN law).

Here Are Some Tips On How To Design An Overflow Pool

A zero-edge pool or an infinity pool can be drawn in various ways.

An outline of the pool is used to place the pool on the land and a section indicates where the bottom is to be located. The document can then be used to file a declaration of work and hire a pool builder.

Plan designed with a drawing program has greater precision. Adding trees and deckchairs is possible, but this tool has no answer to questions such as how to make an overflow? What amount of water should be in the balance tank? How should the parts in the pool be sealed (inlets, bottom drain, etc.)? And many more?

To build a pool yourself, a plan is essential. An infinity pool designer shares his expertise by presenting plans compatible with self-construct. His mission is to propose plans that can be accomplished by a company that is not specialized in pool construction.

The Right Equipment: How To Choose It?

The space where people swim, and the plant room are connected by a system that circulates water. They may also include optional equipment that makes bathing more enjoyable.

The mandatory equipment

You will find the following items in a pool plant room:

  • The filtration pump and the pool filter work together to remove dirt from the pool.
  • It is necessary to have an electrical control panel to operate the pool equipment.
  • To ensure optimum water levels in the pool, a balance tank water level regulator system is installed with sensors.
  • A non-return valve ensures water flows in the right direction.
  • The use of a solenoid filling valve ensures that the water is topped up.

With the addition of various options, a modern pool becomes more functional and practical. Negative edge pools and zero edge pools already possess a rare aesthetic appeal. However, you can also add your details to make your pool more personal.

Options available

Some of them need to be installed at the same  time as the infinity pool is being constructed. One such system is counter-current swimming, which transforms a small pool into a swimming corridor. Submerged roller shutters can be installed later, but their housing must be constructed concurrently with the pool masonry.

Cleaning a pool and reducing maintenance product use are often challenges. An electrolyze, for example, is an automatic system that facilitates the maintenance of the pool and reduces the consumption of maintenance products. It is generally necessary to use a heater if you intend to bathe for a prolonged time; a heat pump is an obvious choice over an electric heater.

 

Reday to build an infinity pool

Creating an overflow pool is an exciting endeavor, but it should be approached with equanimity. Here are some tips for making your dream pool a reality without blowing your budget:

Conclusion

Building a pool does not necessarily involve erecting walls or installing filtration systems. Self-building involves varying degrees of involvement. DIY is an alternative to a kit, which provides no flexibility (imposed shapes and sizes), as well as to a pool builder, whose prices are sometimes out of reach.
