Indoor Pool Design Considerations

Pool tied to building. Often architects specifying indoor pools will place the pool hard up against one wall with the wall of the building running into the pool. While aesthetically pleasing this opens up a can of worms with regards to the integrity of the pool structure. Settling of the foundations or movement in the building can result in water loss from the pool shell due to the stress involved. It is also impossible to access any services located behind this wall, for example pool lights, return inlets etc. The recommended method in this instance is to locate the pool 350mm from the building that is enough for a coping

Outdoor Pool Design Considerations

Outdoor Swimming Pool With Enclosure

Any of the pool construction methods described in the previous article can be utilised to build an outdoor pool. Outdoor pools do have their own particular design considerations which you need to be aware of, including but not limited to…  Proximity to the house.

Ground Conditions & Ground Water Handling

One common factor in relation to the proper installation of all pool shells is dealing with groundwater. If the groundwater pressure builds up the shell of the pool will be at risk unless the pressure is relieved. Battleships were made of steel, weighed thousands of tons and floated. If the pressure is greater than the water and the weight of the concrete or fibreglass shell, it could lift or float the shell. In concrete pools not only should a hydrostatic relief valve be fitted in the lowest point but also the drainage under and around the structure should be such that the water can easily gravitate to the deepest point

Pool Construction Types

Pool Shell Construction Methods – Differences, Advantages & Drawbacks There are essentially five types of pool shell; those erected above ground; the concrete, the liner, the ceramic modular, and the stainless steel. Most domestic pools are of the ‘freeboard’ design. That is to say that the water level is approximately 150mm below the level of the pool deck or 50-100mm in the case of a compass design line. Surface water draw-off is via a number of surface water skimmers (quantity dependent on overall volume of pool) set into the pool wall at finished water level. A skimmer is connected to the pool’s filtration plant and is under suction from the

The Future of Pool Cleaning

The future is now! Autonomous pool cleaners are not new to the market. In fact, some have been around for almost 30 years!

Having a saltwater generator on your pool has many benefits however the effect of sanitation will not be much different from a traditional swimming pool. The salt in the water of a saltwater pool passes a electrolysis plate which charges the chlorine particle in salt (salt is made of Sodium and chlorine) and creates a chlorine ion.
