Brick and Wall Products
M3 Floodtec offers a range of specialist brick and wall products designed to help safeguard properties from flooding. These solutions help reduce flood damage while maintaining essential ventilation and structural protection.
Reliable Solutions to Help Protect Flood-Prone Properties
Our brick and wall products provide effective flood protection for buildings located in flood-risk areas. Solutions such as anti-flood airbricks, vent covers, meter box covers and tanking polymers help stop water entering through vulnerable openings and surfaces.
Anti Flood Airbrick
The Anti Flood Airbrick is the world’s first BSI Kitemark approved airbrick to protect against flooding. It’s the most efficient airbrick on the market as its superior design is passive. It allows air to pass through but the self activating gate shuts off automatically under flood conditions.
Easy to Install and Long Lasting
The anti-flood airbrick is quick and straightforward to install in most properties. Made from durable materials, it is built to provide reliable flood protection for many years without much maintenance needed.
Available in Five Standard Colours
The anti-flood airbrick is available in five standard colours, making it easy to match with the existing brickwork or exterior of your property. This helps the unit blend in neatly with your building while still delivering reliable flood protection.
Anti Flood Vent Cover
Our anti flood vent covers are specialist solutions designed to prevent floodwater from entering openings that are needed for ventilation, such as air vents for appliances or other areas that let air pass through the building structure.
Strong Aluminium Construction
Manufactured from high-grade 5052 aluminium, the anti-flood vent cover is designed to be strong, durable and resistant to corrosion. This helps protect vulnerable ventilation openings from floodwater while withstanding harsh weather conditions and long-term outdoor exposure.
Bespoke Design
Each vent cover can be tailored to the exact size and shape required, making it suitable for unusual or difficult vent locations. The vent cover uses a specialist flood seal design to help prevent water entering the building while allowing the ventilation system to function when configured above flood level.
Waterstop Water Repellent
This solvent free repellent is made from concentrate, which can be applied to ground surfaces to create a protective waterproof seal.
Helps Protect Surfaces from Water Penetration
This silicone/siloxane water-based treatment creates a waterproof barrier that helps stop water soaking into surfaces such as brickwork, concrete and render. By reducing water absorption, it helps protect buildings and structures from damage caused by heavy rain and flooding.
High Coverage for Large Flood-Risk Areas
Supplied as a concentrated solution, a small amount can treat large surface areas that may be exposed to water. Just 2 litres of Waterstop produces up to 25 litres of usable treatment, making it suitable for protecting walls, facades and other surfaces in flood-prone locations.
Tanking Polymer
Tanking polymer is the perfect solution for below ground waterproofing and vertical DPC membrane for above ground applications. It contains an acrylic polymer which imparts improved strength, bonding, and abrasion resistance.
Protects Structures from Water Pressure and Damp
Tanking polymer creates a strong waterproof barrier that helps protect structures from pressure water, ground moisture and dampness. This makes it suitable for basements, foundations and other areas where water penetration can cause long-term structural damage.
A Strong, Durable, Protective Bond
Formulated with an acrylic polymer and cementitious base, the coating provides excellent adhesion to surfaces while improving strength and abrasion resistance. Its durable, microporous structure helps keep long-lasting waterproof protection for internal and external applications.
One Way Weep Vent
One way weep vents are fully permanent solutions that protect the narrow weep holes in cavity walls to stop water from coming through.
Automatically Helps Stop Floodwater Entering Walls
The one way weep vent allows air to move through cavity walls as normal, helping the wall breathe and release condensation. If floodwater rises, the built-in valve automatically closes using water pressure to help stop water entering through the weep hole.
Easy Installation in Existing Weep Holes
This vent is designed to fit into standard 10mm weep holes, making it a simple retrofit solution for many buildings. Its secure fit helps keep out insects and debris while still allowing proper ventilation within the wall cavity.

Frequently Asked Questions
What is flood protection ventilation and why is it important?
Many buildings have ventilation openings such as airbricks, vents and weep holes that let air circulate through walls and floors. While these openings are important for preventing damp and condensation, they can also allow floodwater to enter during flooding.
Flood protection ventilation products are designed to solve this problem. They allow normal airflow during everyday conditions but help block or control water if flooding occurs, helping to protect your property while maintaining proper ventilation.
