In most provinces, it’s necessary to get a building permit for a swimming pool with a water volume of 100 cubic meters. Fortunately, common garden pools hold significantly less water, and therefore don’t require any permit to build. For example, a round pool eight meters in diameter and 1.5 meters deep only contains 75 cubic meters of water. It is, therefore, not subject to approval. So, in this article, we’ll explore how you can build your own small garden pool.
Tips for Pool Building: Structural Conditions
To build a pool is a relatively complex project. So, in order to avoid any unpleasant surprises, it is well worth the effort to consider a few things before and during the construction:
In order for the water to heat up to a pleasant temperature in the morning, the pool should be oriented to the southeast. In this position, it is exposed to sunlight for the longest duration. You can also put in a heater. However, this requires thinking ahead of time to locate the pool near a power source.
Before deciding on a specific pool type, the soil should be tested. If the soil is too soft and will settle, this will eliminate some kinds of pools that could crack. If the soil is soft, it is recommended that you get a concrete or metal basin for the pool, rather than plastic or fiberglass. Ideally, the substrate should be firm and level. Rocks and roots should always be removed, so that no damage to basin will arise. In most cases, regardless of soil type, it is advisable to place the pool on a 15 to 20 centimeter thick concrete slab. This will rule out any unwelcome bumps as well as future settling and cracking.
The larger the swimming pool, the deeper it needs to be embedded in the ground. For a pool with a depth of 1.5 meters or more, the pool should protrude no more than 2/3 of its height. The reason for this is the high pressure that the water will exert on the outer wall of the pool.
Make sure that all the pipes installed in the pool have a slight slope toward the pool. This will prevent any accidental emptying of the pool. Also, make sure these pipes are beneath the ground and insulated to prevent them from freezing in the winter.
Finally, if the pool is going on top of a structure, make sure that you have the structure evaluated by a professional to determine whether it can bear the weight of a pool full of water. For example, if you live in an urban environment where space is tight and you want to put a pool on your rooftop garden, make sure you call a professional to see if your rooftop can support a pool. The pros at Capital Construction recommend that “regardless of how old the house is, homeowners should know how much weight in PSF the roof can hold to prevent damage or total roof collapse.”
