The unit complies with standards of the Federal Emergency Management Agency (FEMA) and Federal Insurance Administration (FIA) for use on doors in flood-prone areas.

*A Note about FEMA Certification: FEMA neither certifies products nor sends out individualized approval of products. However, this flood barrier does satisfy FEMA Technical Bulletin 3-93 which describes design, construction, planning, and certification requirements for the flood proofing of non-residential buildings under NFIP regulations. Flood Ark’s Flood Barrier System for doors has been engineered to far exceed FEMA’s definition of flood proofing.

Most importantly are the “real world” tests in over 7,000 installations since 2004.  The UK and other European countries have been addressing flooding in their cities for decades longer than the US.  After evaluating all of the available choices for flood prevention products for homes and businesses, TSS chose a time tested and proven product for our US solution to preventing flood damage to homes and businesses.  All of the “gimmicks” and poor designs out of aluminum planks and panels have already been flushed out of use in the UK and Flood Ark has remained as the proven flood barrier of choice for decades.  Flood Ark USA, located in Texas, provides Flood Prevention Systems that Work!

Tested to Meet Global Standards

BSI Flood Protection ASTM International

Our flood barriers are patented in 8 countries around the world and have been tested by globally renowned institutions – consistently demonstrating their ability to withstand floods, tornados and hurricanes. The British Standards Institution has awarded our flood protection barriers their Kitemark – a symbol of quality and safety only bestowed on the very best products. Hurricane resistance has been tested by the American Society for Testing Materials.

Report on the Flood Ark uPVC-Extruded Boards Flood Protection System prepared by M. Sadegzadeh BSc MBA PhD C Eng MICE

Test-specific experimentally designed tank: A steel water tank – 98 inches x 49 inches x 49 inches was constructed with 36 inch x 30 inch open front. Open front section building brick-lined to represent a typical house front with doorway.

Procedure: Flood Protection System frame fixed in front of the tank-opening. The uPVC boards were fitted into place and the tank was filled with water up to a level of approximately 43 inches. (At this water level, uPVC sections exposed to a uniform pressure of 5KN per meter run).

Results: Visual examination of system found that all sections were in perfect condition with no signs of damage or distress. No leakage found either between uPVC boards or from sides or bottom of sections.

Test duration: Approximately 24 hours.

Conclusion: uPVC boards found to be lightweight easily assembled, extremely strong and watertight up to 43 inches of water. Based on the given results, the Flood Protection System can provide effective flood protection in situations similar to the test conditions used here.

World Renowned BSI Kitemark Certification:

The British Standards Institution (BSI) Kitemark is recognized around the world as a symbol of excellence. BSI awards their Kitemark to products that have been rigorously tested to ensure the highest of quality and safety standards are met. Flood Protection is one of a range of sectors covered by the Kitemark scheme and Flood Ark barriers are accredited. In order to keep the accreditation, we undergo regular inspections. Not a problem for us. We are only too happy to demonstrate that we continue to manufacture all products to the same high standards of quality that won us the Kitemark accreditation to start with.

Products That Meet High Specifications

There are countless products available in the various markets for which BSI sets standards. The Kitemark has only been awarded to 2500 of the very best. The most recent specification for Flood Protection products is PAS 1188-1:2014. The ‘PAS 1188’ indicates that we are looking at Flood Protection products. The ‘1’ indicates the type of product – in this instance: ‘building aperture protection barriers’. The ‘2014’ indicates how recently the specifications have been set out. Higher specifications were introduced in 2014. Our flood barriers passed with flying colors at that assessment and at our most recent reassessment on February 12, 2018.

Following extensive consultation, the most recent revisions to the Kitemark criteria were introduced in July 2014. The aim of the updated specification is to drive up standards across the industry – something that we wholeheartedly approve of. To ensure that our barriers meet the latest PAS1188-1 specification, we therefore had to go through the testing process once again and are delighted to have been informed this afternoon that our barriers have passed the Kitemark examination.

Replicating Real Life Scenarios 

The barriers have been tested at the HR Wallingford testing facility for the past two weeks. HR Wallingford is the national laboratory for the testing of flood protection products and has not only been approved by the British Standards Institution (BSI), but is also supported by the Environment Agency. Unlike previous test conditions, the 2014 criteria have been designed to replicate real life scenarios as closely as possible and this has led to a number of amendments to the testing process:

  • Fitting Of The Barrier:In previous tests our team was invited to erect our barrier at the center in preparation for the test. In order to achieve realistic test conditions, the 2014 criteria limits the input our team can have to an explanation and demonstration of how to fit the barrier – similar to that which we would give to all customers during the installation process. The final deployment of the center post and flood boards for the test must be carried out by examiners.
  • Allowable Leakages:Compared to the 2009 criteria, the leakage test allowance has been more than halved.
  • Deployment Guide:Each system should be supplied with a waterproof deployment guide and user manual that can be easily followed in the event of a flooding scenario. In the case of our system, each barrier is supplied with a waterproof deployment sticker on the rear of top board and additional guides can also be printed from our website.
  • Maximum Water Depth:The maximum water depth that a barrier can be tested at has been increased, with the minimum level now set at 21 inches. On this occasion we have chosen to have our barrier tested against the maximum level allowed – 32 inches.
  • Maximum Aperture Width:With many people choosing to install large slide and fold patio doors in their homes, there is a need to test flood defenses against wider openings. The maximum aperture size has therefore been increased from 95 inches to 236 inches. Our barrier has been tested at 158 inches, which is the maximum that HR Wallingford could accommodate.


With both a barrier system and air brick cover in place, the team at HR Wallingford carried out three 48 hour tests. This included three static head leakage tests, two wave leakage tests and two current leakage tests. After each test the water was thoroughly drained from the test facility, the barrier dismantled and a 24 hour rest period allowed before the barriers were deployed again. In passing every test, our barriers have proven that they can withstand even the most severe of flood events.
