Assess Pool Damage and External Pressure Source

What happens here

The video begins by visually inspecting an inground pool experiencing structural damage. A significant fracture and separation are evident between the pool's coping/decking and the main pool liner, indicating that the pool wall is bowing outwards. The narrator points to an adjacent large boulder waterfall, identifying it as the source of external hydrostatic or physical pressure causing this outward displacement of the pool structure.

Goal: Understand the extent and probable cause of the pool's structural damage.
