Note: Your Airbrick Cover is not a permanent fixture. Under non-flood conditions, your cover should be cleaned & stored in a safe, dry space. This maintains airflow during non-flood conditions.

•  Tested in accordance with the requirements of Bsi 851188 - 2019 to a flood depth of 600mm. This allows a leakage rate of 10ml per cover, per hour.

•  Produced from aluminium sheet & closed cell EPDM foam, making it impermeable to air & water.

•  Designed to temporarily cover masonry airbricks, but not to be used on steel air vents.

•  Designed to be installed prior to a flood. Fitting during a flood event, or in a submerged setting, is not advised.

•  Your airbrick cover is a manually installed product, using thumb screws to compress the cover into its anchor sleeves. Your seal will only work effectively against smoother faced masonry with flush finished mortar (not uneven stone or a raked mortar finish for example). A risk assessment from a flood professional can assess each aperture for suitability.

Application & Installation Preparation:

The cover can be installed against any existing masonry, brick, or plastic grillage, providing that the opening is no greater than 280mm x 140mm & is suitable to be defended. The existing air brick must be clean and free from loose material and obstructions, as should the surrounding wall face.

The pointing to the brick or masonry around the airbrick must be in good condition, flush & not cracked or broken.

A minimum of 20mm is required around the airbrick on all 4 sides, as this provides the area around which the cover will seal.

Your Airbrick Cover kit:

1 x Anti-Flood Airbrick Cover  -  2 x Plastic Thumb Screws  -  2 x Rubber Washers  -  1 x 10mm masonry drill bit  -  1 x drill hole template  -  Fitting/Maintenance Instructions

Step 1: Check the suitability of the existing airbrick, as well as the pointing. If needed, repoint the area (to a neat flush finish) first & leave to cure.

Step 2: Position your drill template to the wall, central to your airbrick. The two drill holes should be equidistant from the centre, lining up horizontally.

Step 3: Mark the 2 holes through the template.

Step 4: Using the drill bit provided, drill the holes approximately 45mm deep. Clean the hole out of dust & debris.

Step 5: Insert your nutsert into the hole, flush to the face of the brickwork.

Step 6: Fit your airbrick cover, inserting your thumbscrews through the washers & into the nutserts, compressing the seal by tightening. Don't overtighten & damage the nutsert thread.

Step 7: Post flood-event. Unscrews and remove the airbrick cover & gently clean all items (don't use harsh chemicals). Leave to dry and store in a safe dry place.

  • What is Property Level Protection (PLP)?
    Property Level Protection (PLP), which is also referred to as property level resilience, are measures that can be taken to reduce the impact of flooding. They can be categorised into the following two groups: – Flood resistance measures involve trying to stop the water entering the property in the first place. These can usually be fitted to the outside of a property to prevent or limit the flood water getting in and can include flood boards, air brick covers, non-return valves and pumps, as well as work to ensure that the fabric of the property is sound. Flood resilience is about reducing the damage to the inside of your property in the event water does enter and speeding up the time it takes to recover after a flood. Such measures that can be taken include using porous plaster, fitting solid floors or tiled floor coverings, raising electrics to preserve the electricity supply and taking simple steps in a flood event to move furniture and valuable possessions upstairs to lessen the damage flood water can cause.
  • Can You Fit Defence Products to Commercial or Listed Properties?
    To commerical properties yes, listed buildings or conservation areas - maybe. Conservation areas or listed buildings may have restrictions on what's allowed, and some compromises may be made on options available and their installation. This can include colour coding to match the buildings, décor or installation reactive measures which are not visible until deployed. Commercial properties usually have more or larger openings that require defending, as well as a larger area. This usually costs more money, so we recommend, where possible, ways of limited damage if a flood occurs (such as raising electrics or stock).
  • Will Flood Defence Items spoil the look of my house?
    Some flood defence options have the option to not be visible (such as repointing, water resistance plaster and spray to reduce seeping through the walls). But most flood defence products will require some type of fixing or installation point, such as sump pumps or barriers.. If visibility is of great importance to you there are passive flood defences options such as flood doors and airbricks that look almost identical to a regular door but with defences in their structure and mechanisms. It is important to consider the primary function of flood measures - to stop flooding, with their aesthetic appeal being lower on the list of priorities.
  • Should I Choose BSi Kitemark Products Where Available?
    Absolutely! In the case of flood protection products, the Environment Agency recognises the value of BSI Kitemark certification. Following the terrible floods in late 2013 and early 2014 HM Government stated in their 2014 Flood Support Systems Guidance Note: “Where appropriate, all products should ideally carry the BSI Kitemark for flood protection products (PAS 1188) or similar standards”. This is because the Kitemark shows products have been tested to a rigorous and high standard.
  • Does Having BSi Kitemark Products Installed Guarantee My Property From Flooding?
    The Kitemark is an accreditation given by a private organisation known as the British Standards Institute (BSI). The Kitemark accreditation does not guarantee the installation of the product. Products that carry the Kitemark still need to be installed correctly to stop the ingress of water. A Kitemark does, however, prove that a product has been rigorously tested to be ‘fit for purpose’. Unfortunately, whichever products are installed, we can’t guarantee your property from flooding (hence the terms mitigation and defence).
  • What is Fluvial Flooding?
    Fluvial flooding occurs when rivers overflow and burst their banks, due to high or intense rainfall.
  • What is Pluvial Flooding?
    Pluvial flooding, or surface water flooding, occurs when the drainage systems (mostly urban) become overwhelmed and the excess water cannot be absorbed.
  • Can Flood Barriers or Reactive Products Be Left in Place?
    Most flood barriers are not designed to be left permanently in place as they can cause wear and tear (especially due to the external elements).
  • Do My Flood Defence Products Need Maintenance?
    We recommend that as a minimum, any products should be inspected or serviced annually (with some products being tested). Also, following any flood event all products are thoroughly cleaned and inspected for damage.
  • What is Passive vs Reactive?
    These terms refer to whether you need to physically deploy your flood defence measure before a flood event. Passive items work automatically. These measures include: Flood Doors (when the handle is lifted); Anti-Flood Airbricks (closes a valve); Sump Pumps (float switch); & Non-Return Valves. Reactive measures refer to items that do not work automatically. These include items such as the Toiler Bung; Flood Defence Barriers & Puddle Pumps. Passive measures are typically better, but generally cost more than their reactive measure counterparts, so homeowners may have to find a balance of budget vs the item they use to defend their property.
  • Can sand bags stop flood water?
    No, they can't, & the industry needs to stop promoting & encouraging these items as defence. They provide barely any protection, are messy & are contaminated post-flood - making their disposal problematic for both the homeowner and local authority. Floodsax are a great alternative to sandbags, being reasonable priced & providing much more protection. However, installing proper properly level or community level defence is much better.
  • Can I fit flood defence items myself?
    Yes you can, though some items are easier than others. Toilet bungs, some Non-Return Valves & FloodSax are quite easy for homeowners to deploy. Anti-flood airbricks, other Non-Return Valves are more difficult but still quite achievable for the competent DIY'er. Some defence measures do required a specialised & experienced tradesperson, such as Flood Defender Doors, Barriers & Sump Pumps.
  • Can I stop my garden from flooding?
    Short answer, it depends. There are measures to mitigate the flooding, such as improving ground/soil drainage, installing soakaways, ensuring drains are kept clear & having sump pumps installed. However, if the flooding is quite serious, & the area surrounding your property is also flooding - or passing cars are causing tidal effects, only a form of Bung Wall and pump system will enable you to stop your garden from flooding. This can be quite expensive, & funds may be best spent letting the garden flood, but defend your property instead.
  • Do the airbricks have a back or front?
    Yes. The front of the airbrick has the removable film covering, which also states 'Front' to avoid any confusion.
