Inground pool base material creates a smooth and supportive surface beneath the pool liner. Vermiculite based materials are commonly used to form a cushioned pool floor that improves comfort and helps protect liners from wear. A properly prepared base supports even weight distribution and reduces the risk of wrinkles or liner damage. Base material is typically installed during new pool construction or liner replacement projects. Many installations pair base material with vinyl pool liners to ensure proper fit and longevity. Preparation often includes structural components such as pool panels to create a stable and durable pool foundation.
