Flood Control Products

After the catastrophic floods and extensive flood damage inflicted by Hurricane Katrina in 2005, and the massive flood in Houston from Tropical Storm Allison in 2001, the value of flood control in hurricane prone areas is of major concern. In a concerted effort to provide the best available technology in flood mitigation, Hendee offers a variety of emergency flood response systems, both active and passive, for commercial property as well as residential structures. These flood control barriers have been rigorously tested, and the innovative engineering has been proven highly effective in flood protection. Each system has been designed for ease of quick installation and time sensitive response when adverse situations threaten. Whether it is a flash flood or steadily rising water, having Hendee plan and install a state-of-the-art flood control system can help restrain the natural hazard at hand. If you have property to secure from the risk of flooding, take a close look at the various ways Hendee is making flood proofing a viable option.

Rapidam

The Flood Barrier’s Rapidam system requires the pre-flood installation of a bolt down barrier by professional installers. Prior to the potential of flooding, the Rapidam system is unrolled and fastened to the preset bolts. The system is typically delivered in 30-foot lengths that are joined together by means of a patented five-tooth ziplock. All RAPIDAM flood barriers are joined together by zipping the lengths of barrier material to each other and then adding an extra measure of security with french lacing over each zipper to provide increased durability. Two men can deploy approximately 20 yards of the system in about 10 minutes. The material the barrier is treated with anti-U.V. fungicide, Alkali and can be tailored to a wide range of fluid containment requirements. The flexible characteristic of the barrier itself, allows for it to conform to almost any shape requirement, or linear length demands mandated by a specific job.

The Rapidam tension membrane system was tested and certified by the B. S. I. to withstand more than a ton of water pressure per meter of the barrier. This sturdy system can withstand wakes from emergency vehicles and boats, as well as impacts from floating debris, when installed correctly. Rapidam conveniently rolls up for easy storage and reuse.

Rapidams can be used for field applications when fastened with the American Earth Anchor system. The flexibility of the system allows for its use in changing terrain and on different planes. The system comes in standard heights up to 7-feet and has proven to have the lowest installation times of any similar product on the market.

The freestanding RAPIDAM barrier is for use where no ground preparation is feasible or practicable. This barrier is installed by driving metal pins through the eyelets along the leading edge of the barrier and placing a line of sand bags along and on top of the metal pins. This freestanding barrier has all of the benefits of the bolt down system, with the added advantage of having no permanently fixed anchors.

FloodBreak AutoGate™

A revolutionary system that has incurred enormous growth recently is the FloodBreak AutoGate™, a passive system that is permanently installed at any vulnerable flood path including doorways, garage entrances and other breaches in exterior walls. The system should ideally be considered during the design phase of the structure, but can also be successfully retrofitted in most situations.

Autogates™ rigid barriers are installed flush to the floor surface and are unobtrusively covered with any material from carpeting to concrete.  It is the only product available that can withstand severe point and torque loads such as trucks rolling over the system repeatedly. Each gate is equipped with adequate drainage into the storm sewer, back to the street, or into a sump. When the storm sewer fills up, the water fills the pan, thereby forcing the buoyant panel upwards. When flooding is imminent and excessive water begins to accumulate in the immediate vicinity of the protected openings, the AutoGate™ begins to float and rotate upwards. As the water builds up around the structure to which the barriers are connected, the rising water passively lifts (no people, no power required) the floodgate into place. The hydrostatic pressure of the backed-up floodwater pushes the barrier closed as it rises and seals it against a rubber flange. Once a flood has begun, the barrier will be held shut by the water itself and cannot be opened until the water level has sufficiently receded.

Each AutoGate™ unit is shop tested, then retested at the installation site. Numerous FEMA subsidized projects in Houston are currently protected with site-tested FloodBreak Autogates™ including twelve installations around the 1.6 mile perimeter of the M.D. Anderson Cancer Center which opted for the system after undergoing the horrific flooding of 2001. The barriers have been designated a “sole source” acquisition product, a FEMA approved flood mitigation option.

Flood Barrier Rigidam

The Rigidam is system of removable flood barriers that are attached to structures by pre-installed anchors. This simple, but highly effective system does not require a permanent frame to be fastened to the structure being protected. The Rigidam system is most appropriate for small-to-medium openings such as windows, sliding doors and storefronts. Each panel is edged with a watertight gasket that becomes tighter as the hydrostatic pressure against it increases.

Three standard size ranges are available. They include Rigidam
4.0 with standard heights of 2’- 0”, 3’- 0” and 4’- 0”, Rigidam 5.6
with standard heights of 5’- 0” and 5’- 6” and Rigidam 7.6 that
features standard heights of 6’- 0”,6’- 6”, 7 - 0” and 7’ - 6”.
Maximum panel width is 12’ – 0”, and panels can be joined to each
other to make as wide of barrier as necessary.

The engineered system has been tested and certified by the National Flood Insurance Program, and the Florida Building Code, 2001 high velocity winds standards, and it meets applicable NFIP, Army Corps, requirements for flood barrier design, specifically Title 44 Code of Federal Regulations and parts 59 & 60 of the insurance regulations. Rigidam has been designed to meet all requirements for hurricane conditions, specifically the Florida High Velocity Hurricane Zone provisions of the Florida Building Code, 2001 edition, formally known as the South Florida Building Code.
