Our Products
M3 Floodtec provides a comprehensive range of Property Flood Resilience (PFR) products for homes, businesses, infrastructure and community projects. Our solutions are designed to help reduce the different ways floodwater can enter a property, including through doors, windows, walls, ventilation openings and drainage systems. Supported by in-house product development, manufacturing expertise and our BSI-approved Flood Test Facility, our range includes independently tested products alongside solutions designed to manage flood risk above and below ground.
Independently Tested Performance
M3 Floodtec became the first company in the world to achieve certification to the new British Standard BS 851188, which replaced PAS 1188, for a flood resistance product range.
Our certified range includes Flood Defender Doors, the Flood Defender Barrier, Flood Defender Window and Anti-Flood Airbrick. These products are independently tested and certified to BS 851188 and carry the BSI Kitemark™ under Licence No. KM 713574.
The Kitemark gives customers confidence that these products meet recognised standards for flood resistance.
Our continued research and product testing at our own BSI-approved Flood Test Facility further supports our commitment to quality, performance and ongoing product development.
Flood Barriers
M3 Floodtec provides flood barriers for doors, garages, entrances and larger access points across residential, commercial and infrastructure sites. Our range includes removable barriers, stacking Stop Log systems, swing barriers and self-activating solutions, allowing the type of protection to be matched to the property and how the area is used.
Choosing the right flood barrier depends on factors such as the size of the opening, expected flood depth, available warning time and whether manual or automatic deployment is most practical.
Flood Defender Doors
M3 Floodtec provides specialist flood doors designed to combine everyday access and security with built-in flood resistance. Our range includes UPVC, Composite, Timber and Steel Flood & Security Doors, with single, double, low-threshold and escape-hatch options available across selected ranges.
Our UPVC, Composite and Timber Flood Defender Doors, including UPVC French Doors and Low Threshold UPVC and Composite options, are independently tested and certified to British Standard BS 851188 and carry the BSI Kitemark™ under Licence No. KM 713574.
Flood Gates
Flood gates provide a practical way to help protect driveways, entrances and access routes where a removable barrier may not be the most suitable option. They work as normal gates during everyday use and can be closed when flooding is expected.
Our range includes pedestrian, vehicle and larger flood gate systems for homes, businesses and infrastructure sites. Each solution can be selected around factors such as opening width, access requirements, location and expected flood conditions, helping provide long-term flood resilience without unnecessarily restricting normal access.
Flood Defence Walls
M3 Floodtec provides flood defence wall systems for residential and commercial applications where a single doorway barrier may not provide enough coverage. Solutions can be used across wider openings or alongside buildings to help reduce the movement of floodwater into vulnerable areas.
Our systems use durable materials and can be configured around practical site requirements such as opening width, access, visibility and everyday use. This makes flood defence walls suitable for larger or more complex areas where extended flood protection is required.
Flood Resilient Windows
Windows can provide another route for floodwater to enter a building, particularly where openings are positioned close to expected flood levels. M3 Floodtec provides specialist flood resilient Timber or UPVC windows designed to help resist water ingress while continuing to provide the light, visibility and everyday function expected from a standard window.
The M3 Floodtec UPVC Flood Defender Window is independently tested and certified to British Standard BS 851188 and carries the BSI Kitemark™ under Licence No. KM 713574.
Brick & Wall Products
Floodwater can enter through less obvious parts of a building, including airbricks, vents, weep holes and porous wall surfaces. Our brick and wall range includes anti-flood airbricks, vent protection, one-way weep vents, water-repellent treatments and waterproof tanking solutions designed to help reduce these risks.
The M3 Floodtec Anti-Flood Airbrick is the world’s first BSI Kitemark™ certified anti-flood airbrick. It is independently tested and certified to British Standard BS 851188 and carries the BSI Kitemark™ under Licence No. KM 713574. It also complies with BS 493:1995 for wall ventilation, providing 2400mm² of free airflow so it continues to function as a ventilating airbrick during normal conditions. Its self-activating design allows air to pass freely during everyday conditions before automatically closing as floodwater rises.
Sewage Backflow & Water Management
Floodwater can also affect a property through its drainage system. During heavy rainfall or flooding, overloaded drains and sewers can cause wastewater to flow back towards toilets, sinks and other outlets, while surface water and groundwater may also need to be removed.
Our sewage backflow and water management range includes backwater valves, non-return valves, sump and pump systems, puddle pumps and inflatable toilet bungs. These products are designed to help control excess water and reduce the risk of sewage or wastewater entering a property through its drainage system.
