FAQ – AquaLOCK® One‑Piece Door Flood Protection
The AquaLOCK® One-Piece Door with flood protection combines a classic one-piece door with an integrated AquaLOCK® sealing system. The AquaLOCK® One-Piece Door provides high sealing performance, reliable flood protection, and prevents water from entering vulnerable building areas such as garages or basement entrances.
Integrated Flood Protection
A perimeter sealing system fully seals the door to prevent water ingress. No additional barriers or external protective measures are required.
High Protection Performance
Depending on the configuration, the system protects against water levels of up to 1,600 mm and retains up to 99.9% of water. This makes it ideal for residential, commercial, and industrial areas with increased flood risk.
Robust Construction
A reinforced frame and door leaf construction is designed to withstand high hydrostatic pressure. This ensures long-term stability and reliable functionality.
Conclusion
The AquaLOCK® One-Piece Door provides integrated, certified flood protection up to 1,600 mm – without additional barriers – ensuring long-term protection of buildings against water ingress.
The AquaLOCK® One-Piece Door protects against flooding through an integrated sealing system and reinforced construction. When closed, it automatically creates a watertight barrier that retains up to 99.9% of water, reliably protecting buildings from water ingress – without any additional protective measures.
Perimeter Flood Sealing System
When locked, the perimeter sealing profiles press evenly against the frame and floor. This creates a near-complete seal that retains up to 99.9% of water and effectively protects the interior.
Mechanical Compression During Closing
The defined contact pressure of the locking mechanism ensures that the seals remain effective even under high hydrostatic pressure. The mechanical compression prevents deformation and reliably protects against water penetration.
Reinforced Frame and Door Leaf Construction
The robust steel frame and stable door leaf construction prevent deformation under load. This ensures that the sealing performance remains stable even at water levels of up to 1,600 mm.
