FAQ – AquaLOCK® Flap Flood Protection
The AquaLOCK® Flap is a high‑performance flood protection element designed for smaller openings up to 1300 × 1300 mm, such as technical access points, service hatches, utility openings and similar structural apertures. It is engineered to provide flexible and effective protection where doors or large systems are not suitable.
The AquaLOCK® Flap is designed to deliver flexible, high‑performance sealing for small to medium‑sized openings. It prevents water from penetrating by using a specialized closure system engineered for high water resistance.
