Flood Proofing / Flood Fighting Product Categories

 

The National Flood Barrier Testing & Certification Program is testing/certifying products that are designed and marketed to be used to provide flood risk reduction to facilities that are exposed to flood risk such as buildings.  These products are intended to provide flood risk reduction to residential, commercial, agricultural, and industrial property.  They are generally categorized into the following five broad categories:

Temporary Barriers:

Temporary Barriers are intended to provide temporary flood risk reduction.  These barriers are generally setup just prior to a flood event and are generally taken down immediately after the flood threat has passed.  Setup of these barriers does not require any permanent fixtures to which the barrier is attached.  Flood warning times prior to the flood event must be long enough in order for these barriers to be setup and become flood worthy.  Temporary barriers are basically of two general types depending upon the method of making the barriers stable to resist the forces of flood water.  These methods are generally water filled or sand filled in order to provide product weight and hence stability and using the weight of the flood water itself on the barrier to anchor the product and provide the needed stability.  Depending on the product, they can generally be deployed in a large variety of conditions.  These products are usually the flood proofing system.

Semi-Permanent Barriers:

Semi-permanent barriers also provide temporary flood risk reduction.  They also rely on having enough flood warning time in order to be able to erect the barrier and they are generally erected just prior to the flood and removed shortly after the flood.  These products rely for stability on an anchoring mechanism that is permanent attached to the ground upon which these products are erected.  These products are usually the flood proofing system.

Closure Devices:

Closure Devices are intended to close openings in flood proofing systems.  They are generally categorized as closing window and door openings into buildings.  They are usually a part of a permanently installed flood proofing system. They are removed from their closure position after the flood event passes in order to be able to freely use the opening that the product closed.  These products are part of a flood proofing system.

Backwater Valves:

Backwater Valves generally are used in sewer and drain systems to prevent the flow of flood water through these systems and into the building or structure desiring flood risk reduction.  These devices are permanently installed and do not function until flood water reaches sufficient depths that will allow the water to flow into the building via the sewer or drain system.  These devices are part of a flood proofing system.

Sealants:

Sealant products are generally used to coat material that is not completely resistant to the passage of water when exposed to floods.  The sealant material is applied in order to make the material water proof in terms of the passage of water through the material.  These products are permanently applied.  They are part of a flood proofing system.

Flood Mitigation Pumps:

Flood Mitigation Pumps are used for the removal of unwanted water. Types of flood mitigation pumps include but are not limited to submersible (ex: a sump pump) and self-priming pumps. Flood mitigation pumps shall be utilized in one of the following applications; as part of an open automatic barrier system, installed in a building and used for removal of unwanted water, and/or as a portable emergency device used for removal of unwanted water from a building.
