Pool Liner Tearing — Alkmaar, Noord-Holland

A torn or punctured vinyl pool liner causes steady water loss, undermines the pool deck as saturated soil shifts, and allows algae to grow behind the liner where it cannot be treated. Tears occur from age-related brittleness, sharp objects on the pool floor, chemical imbalances that degrade the vinyl, or ice damage during winter. A pool and spa technician locates the tear with dye testing, patches small punctures underwater, or measures and installs a full replacement liner when the damage is too extensive to repair.
