Plaster Pool Empty: Risks & Damage from Water Loss

Plaster pools should never be left empty. Leaving a plaster pool without water for an extended period can cause severe damage to the pool's structure. It can lead to cracking, warping, and even collapse of the pool. Plaster is a porous material that absorbs water, so when a pool is empty, the plaster starts to dry out. This process causes the plaster to shrink and crack. In addition, the lack of water can cause the pool's structural components, such as the rebar, to rust, which can further weaken the pool.
