A semi-Olympic competition pool has to meet a number of requirements as defined by the International Swimming Federation (FINA) Facilities Rules.
Semi-Olympic pools, also called short pools, are half the length of Olympic pools and comply with FINA’s minimum dimensions and requirements for the 25-meter competition use.
These pools must be 25 meters long; this pool length (minimum distance between the inner front sides of the pool) must be long enough so that the distance of 25 meters between the two nearest faces of the two panels is ensured when timing touch panels are used at the extreme starting walls or at the turns.
The allowable tolerance on 25 meter pools shall be + 0.010, -0.000 meters when panels are installed.
For pools with panels at both ends, the wall-to-wall distance must be at least 25.020 meters and have a maximum of 25.030 meters.
For pools with a panel at one end, the wall-to-wall distance must be at least 25.010 meters and not more than 25.020 meters.
Tolerances should be consistent from 0.300 meters above to 0.800 meters below the water surface.
When it comes to complying with these pool construction system requirements, there’s no more efficient way than to use Astralpool’s Skypool technology.
Skypool is AstralPool’s prefabricated panel technology that can be adapted to any type of infrastructure to easily, quickly and safely build a pool with guaranteed accuracy thanks to its advanced precision adjustment technology.
Pools must have a minimum depth of 1.80 meters. The water depth of pools with starting platforms must be at least 1.80 meters and the distance from the wall boundary must be 0 to 6 meters.
The end walls must be vertical, parallel and form right 90 degree angles with the swimming lane and with the surface of the water.
They must be constructed of solid material, with a non-slip surface extending 0.8 meters below the surface of the water, so the competitor can touch and push off without danger when turning.
The permissible tolerance in wall verticality must be ± 0.3 degrees.
The “swimmer’s step” (or rest ledge) is permitted along the pool walls; it must not be less than 1.2 meters below the surface of the water and may be 0.1 to 0.15 meters wide. Both internal and external ledges are acceptable, however, internal ledges are preferred.
The lane must be at least 2.5 meters wide, with 8 or 10 lanes in 25-meter semi-Olympic pools.
The space between the wall and the floating line of the first lane and the last lane and the wall must be 0.20 meters. This distance must be kept to reduce or mitigate the ripple effect on the swimmer.
These are the main FINA requirements for building a semi-Olympic pool in compliance.
Skypool is the top choice for building a semi-Olympic pool because of its exclusive technology that delivers unique advantages to pool manufacturers.
Skypool is a construction system made of hop-dipped galvanized steel panels covered in a PVC-P membrane. The panels are extremely resistant to abrasion and corrosion that adapt to any existing infrastructure, whether fixed or temporary.
The Skypool structure is always calculated and adapted according to local seismic regulations. The steel used to construct Skypool panels also withstands higher stresses than regular stainless steel without losing its flexibility.
These completely prefabricated panels have an easy anchoring and assembly system that makes it possible to build an in-ground or above ground pool in record time.
Skypool and its unique technology ensure that the semi-Olympic pools meet FINA requirements in terms of length, tolerances, depth, walls, lanes, etc.
