The concrete pool is definitely the most widely used method even today; this type makes it possible to build pools with any kind of shape, size and height.

A plan issued by a licensed engineer showing thicknesses, iron reinforcements and dimensions is required in each case.

To make this type of pool, an underground or prefabricated technical room is required; the compensation tank will be made by modifying the overflow channel, which at this point will have two functions: overflow channel and compensation tank.

The technical compartment will need to have easy and safe access, as it needs to be accessed frequently during the opening of the pool. This pool features an oversized (depending on the volume of the pool) cascading overflow channel that, depending on the needs and location, runs along one or more walls, creating the Infinity effect.
It is still possible to make the overflow on the other walls and have the water flow into the compensation pool.

The water overflows directly into what is a true open-air compensation tank; from here it is drawn in, filtered by the system and fed back into the pool through the inlets.
Ideal for pools installed on sloping terrain with downstream overflows, with little room to insert the compensation tank.

The dirt (insects and leaves) will not remain floating on the surface, but will be immediately moved to the waterfall, leaving the water mirror always perfect.
