A critical component in vinyl-lined swimming pools, a durable, waterproof membrane installed within the pool’s structure provides a smooth, watertight surface. Constructed primarily from polyvinyl chloride (PVC), this element conforms to the shape of the pool, preventing water from leaking into the underlying structure. As an example, consider its role in an inground pool; it creates a barrier between the water and the soil, preventing erosion and structural damage.
The installation of this element is vital for maintaining the integrity of a pool. It prevents costly water loss, protects the pool’s structure from water damage, and enhances the pool’s aesthetic appeal. Historically, the use of plaster and concrete required frequent repairs and were prone to cracking. The introduction of this alternative offered a more resilient and cost-effective solution, extending the lifespan of the pool and simplifying maintenance.
