Anti Flood Airbrick Covers Key Points
  • Cost effective solution to stop ingress of water
  • Takes minutes to install after first application
  • Available in standard terracotta; other colours available upon request

The M3Floodtec Airbrick cover is a purpose manufactured enclosure with water seal that is designed for temporary surface mounting to an existing Airbrick fixed to an external wall. The Airbrick cover should be bolted into place in accordance with the fixing instructions (see overleaf) prior to the onset of a flood event such that the existing airbrick is sealed prior to any flood water reaching the level of the existing airbrick.

The cover is not a permanent fixture. Once the flood condition has passed and the waters have drained away the airbrick cover should be removed so as to let air flow into the building through the existing airbrick. Failure to remove the cover may result in potential damp issues inside the building.

Quality tested & certified.

Our Anti Flood Airbrick Covers have been thoroughly tested and checked, time and again, and proven to meet a recognized industry standard.

Tested & Certified to KM713574

Cleaning, drying and storage

Following use in a flood event the airbrick cover should be removed, cleaned by washing in clean water, left to dry then stored in a suitable safe place ready for future deployment.

Reusing the Airbrick Cover

The Airbrick cover is a reusable product and can be deployed many times over without detriment to the performance. The Sleeve anchors once installed into the existing airbrick remain in place for future use- there is no requirement to remove these anchors.

Safety Precautions

The Airbrick cover will work as designed so long as both of the fixings are installed and the securing handwheel nuts are tightened as far as possible- these will be sufficient tightened by hand- Spanners are not required. Always make sure that the washers are installed correctly.

Check and inspect the inner foam seal before installing the cover plate, if damaged contact M3Floodtec for advice before deployment.

Make sure the existing Airbrick is clean and free from obstructions and protrusions before fixing.

Once installed and in the event of a flood condition do not attempt to remove the airbrick cover or access the flood water, this is dangerous and could place you in a position of drowning.

Risk Assessment

The use and deployment of any flood defence product should be considered in the context of the building relative to the risk of possible flooding. Single products alone may not give adequate protection to the whole building. It is therefore recommended that a full flood risk survey is undertaken to assess where flooding may ingress into the building and as such what measures should be deployed.

Flood risk surveys should be undertaken by properly trained and accredited surveyors, for details of approved Companies contact the Environment Agency web site www.gov.uk/government/organisations/environment-agency

The M3Floodtec Airbrick cover is designed as a temporary cover to fix over existing airbricks that are part of a general building’s fabric. They can be installed into existing masonry airbricks but must not be used on Steel air vents or existing plastic airbricks.

The product is designed to be installed before a flood event happens and then removed after the flood has passed. The product is not designed as a permanent flood prevention fixture and attempting to fix the air brick cover during a flood event is not recommended.

If deployed correctly the product will protect against a prolonged flood however permanent deployment in a submerged condition is not recommended. If this condition is a potential expert advice should be sought to consider taking the airbrick out of potential risk.

This product has been tested against the standard set of tests as defined in PAS 1188-1:2014 which represent typical conditions that might be experienced during a flood in the UK. This includes testing the product for leakage under static water levels 840mm above aperture threshold level, waves up to 0.1 m high, and parallel currents up to 1.0 m/s.

The testing undertaken under this PAS excludes all other components of the flood protection system. Conformance of the product to PAS 1188-1:2014 does not mean it is suitable for all buildings or locations.

Installation Guide

The Airbrick cover is simple to fix and requires minimal DIY experience, however, if in doubt we recommend that the installation is undertaken by a reputable builder in line with the instructions below.

A single air brick cover should take 5 minutes to install, once the location fixings (the anchor sleeves) are positioned in the existing airbrick the attachment of the cover will take less than 1 minute.

The Airbrick cover can be installed against any existing masonry airbrick. The existing airbrick surface must be clean and free from loose material, protrusions and obstructions before fixing.

If the existing Airbrick is recessed into the wall such that the airbrick cover plate cannot fix tightly to the face of the airbrick advice should be sought from your specialist flood risk surveyor.

It should not be installed onto existing metal air vents or existing plastic airbricks. (alternative products are available for these applications). If in doubt please consult your specialist Flood risk surveyor.
