Our galvanized pool walls are pre-shaped at the factory to allow for the flexibility of custom designs and ensure the most accurate pool shape possible—every time. Our pools are characterized by their ability to resist deformation when a load is applied by ground pressure, water pressure, or frost. The compression locking system is superior to the welded system as it does not destroy the integrity of the galvanized coating. Concrete decks are then poured on a gravel base and embed the top of the pool wall for increased support.
