Ready before the rain.

FlashWall is a portable, folding flood barrier for entrances and building openings. It provides targeted protection at an opening where the fit, mounting arrangement and ground conditions have been assessed in advance.Start with the entrance you need to protect. AquaFence should confirm the model and complete configuration for that opening before you order. Prepare the mounting arrangement and practise deployment before a flood warning.

The standard models differ in section count and overall length: X2 has two sections and is 1,250 mm long; X3 has three sections and is 1,800 mm long; X4 has four sections and is 2,350 mm long. All three are listed as 500 mm high and 660 mm wide.These are overall product dimensions, not guaranteed clear-opening sizes. The mounting arrangement determines the usable opening, so confirm the fit rather than choosing a model from the entrance width alone.

Record the clear opening width in millimetres between the intended mounting surfaces. Note the material and condition of each side, together with any threshold, step, slope, joint or gap in the ground.Send a front-view photograph, a close-up of each mounting surface and a photograph of the threshold. These details help AquaFence assess the fit and identify the required configuration. Do not treat a width measurement alone as confirmation of suitability.

The X2, X3 and X4 models on this page have a listed maximum water depth of 500 mm. Their listed product height is also 500 mm.The appropriate protection limit for your entrance depends on the assessed site and supplied configuration. Follow the product instructions and site emergency plan; do not assume protection above the listed depth or in flood conditions that have not been assessed.

The installation area should be flat, clean, continuous and non-permeable. The barrier must be used with the mounting arrangement and ground conditions specified for your configuration.Flag steps, slopes, gaps, uneven surfaces and changes of material before ordering. Send photographs of any uncertain areas to AquaFence so the opening can be assessed. Do not assume the barrier will compensate for an unsuitable threshold or ground surface.

The mounting arrangement must suit the entrance and be prepared in advance. The accessories on this page include wall brackets, suction-cup components and side connectors; the required parts depend on the selected configuration.Tell AquaFence whether the mounting surfaces are smooth glass or metal, concrete, brick, mixed materials or something else. Ask for written confirmation of the mounting method and components for your opening rather than selecting parts from their names alone.

Yes. Confirm the fit and complete set of components, prepare the mounting arrangement, and read the supplied instructions before the barrier is needed.Practise unfolding, positioning and securing FlashWall at the actual entrance. Include a check of the seals and installation area, and make sure the people responsible know where the barrier and its parts are stored. The aim is a prepared routine before a flood warning arrives.

Plan access before placing a flood barrier across an entrance. Follow the site emergency-access plan and confirm how occupants, staff and responders will use alternative routes while the opening is protected.Include this in deployment training. Do not assume the protected entrance can remain in normal use or that the barrier can be removed during a flood without affecting protection. Resolve access arrangements as part of the site assessment.

Use the instructions supplied with your model and mounting configuration. The preparation described on this page is to unfold, position and secure the barrier, with seals inspected and the installation area clean and suitable.Practise the complete procedure in advance at your entrance. This FAQ is an overview, not a replacement for the installation instructions. Ask AquaFence to clarify any uncertain step before relying on the barrier during a flood warning.

Check the barrier and its seals, confirm that the required mounting components are available, and inspect the entrance and ground for dirt, damage or changes since the fit was assessed.Use the supplied instructions for the detailed inspection routine. If a gasket, mounting part or other component is damaged or its condition is uncertain, contact AquaFence for advice and the correct replacement before relying on it.

Module connectors and side connectors are listed among the accessories on this page. Their presence in the shop does not confirm that a particular combination is suitable for your opening.Provide your existing model, article number, opening dimensions and photographs. Ask AquaFence to confirm compatibility, the complete connection arrangement and its protection limits before ordering components or modifying the setup.

After use, rinse, dry and inspect the barrier before folding it for storage. Follow the supplied instructions for cleaning, inspection and storage of the barrier and its components.Keep the complete deployment set organised and ready for the next warning. If you find damage or deterioration during the inspection, arrange advice or replacement parts before the next use.

The page lists mounting components, connectors, gaskets, a storage bag and other setup items. Match each part to your specific FlashWall model and mounting arrangement.For an existing barrier, provide the model or article number and photographs of the part you need to replace. For a new installation, request a complete itemised configuration so the barrier, mounting parts and quantities are confirmed together.

Send the clear opening width, mounting-surface materials, threshold and ground condition, and photographs of the entrance and both sides. Include your preferred model or custom-length requirement, if known, and any existing equipment details.For the Japan enquiry shown on this page, include the delivery city or prefecture. Ask the quotation to confirm the model, mounting arrangement, supplied parts, quantities, tax treatment, freight and total. The fit-enquiry guide prepares information for review; it does not certify suitability or automatically select a barrier.

The listed price identifies the named product or component. It should not be read as confirmation that every mounting part, connector, gasket or storage accessory needed for your entrance is included.Request an itemised quotation confirming the supplied assembly and quantities. The comparison on this page describes the prices as 2026 Japan EXW list prices; confirm freight, the applicable 10% consumption-tax treatment and the total payable before accepting an order.

The listed custom overall-length ranges are 985–1,535 mm for X2 Custom, 1,535–2,085 mm for X3 Custom, and 2,085–2,635 mm for X4 Custom.These ranges describe the product length, not the clear opening it will protect. AquaFence must confirm the fit, mounting arrangement and correct model before order acceptance, including where two model ranges share a boundary. Send the entrance measurements and photographs before specifying a custom length.

The dispatch time stated on this page is 48 hours. Your order acceptance should confirm when that period starts and whether any exception applies, particularly for a custom order.Dispatch means the order leaves; it is separate from the delivery time to your site. Confirm the delivery destination, coverage, freight charges and expected delivery timing in the quotation and order acceptance.

The written B2B quotation and sales contract define the applicable warranty and return terms. Request and review those terms before accepting the order, including any conditions that apply to a custom-length product.Report damage or non-conformity promptly and contact AquaFence before returning goods. Provide the order details and a clear description of the issue, with photographs where helpful, so the next steps can be agreed.
