Assess Pool Damage and Cause

What happens here

Begin by thoroughly inspecting the pool area to understand the extent of the damage. Observe where the pool liner is pulling away from the coping or pool edge. In this specific case, a significant gap is visible, and the narrator identifies that a boulder waterfall structure is exerting pressure on the pool wall, causing the liner to shift outwards and a fracture in the surrounding concrete. Understanding the cause is crucial for devising an effective temporary solution.

Goal: Understand the problem and its origin.
