How to Choose the Right Solution for Your Property

Doorway & Opening Protection

For front doors, back doors, garages, or large openings, Nautilus Flood Barriers provide robust demountable protection that can be deployed when flood warnings are issued.

Ventilation Point Protection

Air bricks and vents are common weak points. Buffalo Anti-Flood Air Bricks maintain airflow while automatically sealing when water approaches, protecting against groundwater and surface flooding.

Cavity Wall Drainage

M3 One-Way Weep Vents allow cavity wall moisture to drain out naturally while preventing flood water from entering through weep holes—critical for properties in flood-prone areas.

Comprehensive Protection

Most properties benefit from a combination of solutions. Barriers for main openings, air brick covers for vents, and weep vents for drainage points provide layered defense.

Below-ground spaces need comprehensive protection: barriers for access points, air brick covers for all ventilation, and weep vents to prevent cavity wall water ingress.
