Longevity The average above ground pool will last 7-15 years before the structure gives out, although their liners will last 5-9 years before they have to be replaced. For an inground structure, the longevity really is contingent on the type of pool. For example, fiberglass should last well over 20 years. Vinyl pools should have a structure that lasts, but their liner needs to be replaced on average every 6-11 years. As for concrete, their structure should also last a long time, but keep in mind they need to be resurfaced every 9-13 years, which can get very, very expensive.
They should not be attached to the pool for any stability. The pool is essentially just adjacent to the deck. For most above ground pools, these decks will be anywhere between 3 to 6 feet above the ground and must be laterally braced from the beams/joists to the bottom of the posts. Cross bracing in these regions and in both axisâs (north/south, east/west or such) is necessary.
