How TÜV SÜD can help with flood resistance testing

Flood resistance testing evaluates the ability of flood protection products and systems to limit water ingress under defined flood conditions.

TÜV SÜD provides independent testing to assess how flood protection products perform under controlled conditions. Depending on your product, intended application and agreed requirements, testing can include:

  • Static water testing to assess leakage, sealing performance, joint integrity and resistance to water ingress
  • Dynamic impact testing to observe deformation, displacement, damage and changes in leakage performance
  • Wave testing to assess the product and its interfaces under repeated changing water loads
  • Current or flow testing to assess stability, deformation, leakage, connections and seals under moving water
  • Long-duration water exposure testing to assess whether leakage, deformation or seal performance changes over time

During testing, our specialists can monitor water leakage and ingress, deformation, seal and joint performance, component movement, supporting structures, interfaces, and overall structural integrity.

Testing can be applied to flood doors, flood gates, flood boards, flood windows, temporary and removable barriers, modular flood barrier systems, wall and panel systems, sealing systems, joints, and building-opening protection systems.

Our flood resistance testing process

Our testing process assesses your flood protection product under controlled conditions based on its intended application and agreed requirements.

Define the test scope

We review your flood protection product, intended application, installation arrangement, supporting structure and required test conditions to establish an appropriate testing scope.

Prepare the test setup

The specimen is installed in the test setup with the relevant supporting structure, seals, joints and interfaces included within the agreed scope.

Conduct flood testing

The product is subjected to the defined conditions. These may include static water pressure, dynamic impact, wave action, current or flow, and long-duration water exposure.

Monitor performance

During testing, our specialists observe and document relevant characteristics such as leakage, deformation, seal performance, joint performance and structural integrity.

Review the results

We review the observations and results against the agreed test conditions, applicable requirements and acceptance criteria.

Document the test

The test report records the test specimen, setup, conditions, methodology, observations and results according to the agreed testing scope.

Frequently asked questions (FAQs)

 

  • What are the benefits of flood resistance testing? 

    Flood resistance testing provides objective evidence of how flood protection products perform under defined conditions.

    Testing can help identify leakage, deformation, and weaknesses in seals, joints and interfaces before installation. The results can also inform product development and technical discussions with customers and project stakeholders.

  • What is flood resistance testing? 

    Flood resistance testing evaluates how well a flood protection product or system limits water ingress under defined conditions. 

    Depending on the agreed scope, testing can assess barriers, doors, gates, windows, seals, joints, supporting structures and installation interfaces under static water pressure, waves, flow, impact or long-duration water exposure.  

  • Why is flood resistance testing important? 

    Weaknesses in flood protection systems may become apparent when the system is exposed to sustained water pressure, wave action or moving water. 

    Testing can identify leakage, deformation, seal and joint issues, and interface performance under controlled conditions. The results provide objective technical information for product development and project decision-making.

  • How much does flood resistance testing cost? 

    The cost of flood resistance testing depends on the required testing scope. Factors can include the product and its dimensions, installation arrangement, applicable requirements, test conditions and exposure duration.

    Provide your available product drawings, installation information, intended application and required test conditions when requesting a quotation.

  • How long does flood resistance testing take? 

    The duration depends on the agreed test scope and applicable requirements. 

    Long-duration static water exposure may include test periods such as 18 or 24 hours, depending on the applicable requirements and agreed scope. The overall service can also include specimen preparation, additional test conditions, results review and reporting.

  • How often should flood resistance testing be carried out? 

    There is no single testing frequency for every flood protection product or application.

    The appropriate testing requirements depend on factors such as the product, intended application, applicable standard and project specification. Manufacturers and project stakeholders should determine the requirements for the specific product and application.

  • Who is flood resistance testing for? 

    Flood resistance testing is relevant to organisations that develop, specify, manufacture, install or manage flood protection systems, including: 

    • Manufacturers of flood protection products 
    • Infrastructure and building owners 
    • Facility managers 
    • Construction companies and contractors 
    • Developers 
    • Technical consultants 

    Testing can be relevant to applications including commercial buildings, manufacturing facilities, warehouses, data centres, hospitals, underground areas, transport infrastructure, electrical substations, utilities and other critical infrastructure. 

  • Who can be affected by the performance of flood protection systems? 

    The performance of flood protection systems can affect building and infrastructure owners, facility operators, manufacturers, contractors and other project stakeholders.

    Water ingress can also affect buildings, equipment, assets and operations. Independent testing provides technical evidence of how the system performs under the defined test conditions.

  • Which requirements apply to flood resistance testing? 

    The applicable requirements depend on the product, project, intended application and market. Flood resistance testing may be conducted against an applicable standard or agreed project-specific test conditions.

    The applicable standard, testing configuration, exposure duration and acceptance criteria should therefore be confirmed for each product and intended application.

Next steps for flood resistance testing

Plan flood resistance testing around your product, installation and intended application. TÜV SÜD can assess the agreed test conditions and document how the flood protection system performs under controlled exposure.

Discuss your flood barrier, flood door, flood gate or other building-opening protection system with our specialists to define the appropriate testing scope.
