Above-ground pools are a more affordable than in-ground pools, which require digging and serious construction. Above-ground pools can have a ring along the top that only need inflating, or have individual panels and a liner. One important thing to consider before looking at an above-ground pool is where you plan to install it. The pool requires flat space covered in either grass or sand to operate safely.
If you install an above-ground pool on uneven surfaces, the walls can collapse due to uneven pressure. The water presses more on one section and the pool can buckle, twist or break causing damage to your house, property or family. A pool with an inflatable ring is more likely to fold under this increased pressure.
An uneven pool will result in an uneven water level. This may only be a small difference initially, but over time the pool will settle and the difference may increase. A deeper side may be dangerous to smaller children who may not be able to touch the bottom. If your pool has a skimmer and the water is not at least covering it half way, it cannot operate.
If you have chosen an unlevel area for your above-ground pool, the liner may not lay flat causing wrinkles and folds. These can become hooked on pool equipment and tear a hole or rip the liner. Vacuuming equipment would not clean dirt under the folds and the vacuum could also tear the liner.
Choose a location
Before installing the pool look for an area away from trees and at least 90 cm (3 feet) from any other structures in the garden. If you have to level the area, sand makes a good base that can be compacted and can also be a base for paver stones around the pool.
