Pool Hall Structure


The Traditional Approach

In the past (and often in the present as well!) pool hall buildings have been provided with conventional deep strip foundations around the perimeter and the pool tank was shown on the drawings installed in a pit in the ground inside the building.

As a result, all the pool fittings and pipework is buried in the soil between the swimming pool and the pool hall foundations. If there is a leak from any of these fittings your expensive pool hall floor will have to be dug up!!!

Futhermore the ductwork that is required to provide warm dry air to the pool hall glazing has to be provided in ugly overhead ductwork because it is very difficult to protect buried ductwork from rust and corrosion.


The Bluepools Approach

Providing a single flat foundation slab for both the pool and pool hall foundations, as shown here, is no more costly than the traditional method. (Please click on image to enlarge)

I. Bluepools Polybloks

Bluepools prefers to use its Polybloks for every pools that it designs.

In the construction of indoor pools, Bluepools uses the Polybloks for both the undercroft outer walls and the pool walls. The gap between the pool walls and the basement walls is then covered by a conventional beam and block floor of the type normally used in modern house ground floors.

II. Plant Room for Indoor Pools

It is best to build an indoor pool with the pool hall floor at about 150mm above general ground level so that the pool tank and pool plant rooms are below ground. This is the best design from the aesthetic and usability points of view but the basement (below ground areas) need to be structurally robust, insulated, and may need to be provided with land drainage systems.

The undercroft area around the pool as shown in the sketch above will normally have a headroom of about 1.2m and this is more than adequate for occasional access to the pool pipework.

However, the pool plant room really needs at least 2 metre headroom and so one end of the pool undercroft area will need to be deepened by about 800mm or room needs to be made for a plant room at ground floor level that provides access to the undercroft below it.

Completely safe pedestrian access is absolutely essential for all domestic pool plant rooms as it will be necessary to carry chemicals in large containers from where they are delivered into the pool plant room.


III. Pool Hall Walls up to Eaves Level

Cavity Walls need Structural Frames:

Pool hall walls are invariably at least 12m long on the pool hall sides. The cavity wall panels of this length need to be braced every 4.5m to withstand wind loading. As a result, pool halls need to incorporate at least 2 structural frames that can be made form steel or laminated timber.

This results in several disadvantages:


Polyblok walls up to eaves level do not need Structural Frames:

Polyblok walls can be taken up to eaves level without frames if a small quantity of reinforcement is provided in the wall.

This provides the following advantages:
