Product Overview/Function General description- The TrafFix Water-Wall™ is a plastic, water filled portable module that can produce the desired energy attenuation characteristics to decelerate an impacting vehicle to meet TL-1 for Longitudinal Barrier, TL-2 for Longitudinal Channelizing Device or TL-3 for Barricade crashworthy requirements of Report NCHRP 350.
Product Components and General Specifications The TrafFix Water-Wall sections are Orange or White in color and have an outer shell made from virgin low density polyethylene (LDPE) and have a water capacity of 122 gallons [462 liters]. The polyethylene material is durable and recyclable and will break up in large sections upon impact. It will not crack or corrode when left on the job site or stored for long periods of time.
Installation Foundation Requirements The TrafFix Water-Wall is free standing and only requires that the foundation support the weight of the fully loaded sections. The foundations include concrete, asphalt, dirt and gravel. Installation Instructions The TrafFix Water-Wall will be delivered in two pieces. The first piece will be the water wall barrier section with the twist lock fill cap and the buttress threaded drain plug installed.
When the TrafFix Water-Wall has been placed in accordance with the site plan and the sections fastened together, the twist lock fill cap for each section should be removed and the section filled with water. The fill cap is then replaced insuring that all tabs are engaged. If the optional water level indicator is installed, insure that the level indicator becomes fully raised.
Deflection Clear Zone When installing the TrafFix Water-Wall , a clear zone must be made kept on the work zone side of the barrier to allow for lateral deflection into the work zone. When impacted at the design speed of 31 mph [50 kph] at an impact angle of 25° with a 4500 lbs. [2000 kg] impact vehicle the deflection is 15.5 ft. [4.7 m]. This is the minimum clear zone required in the work zone. This clear zone is at the test impacted design speed and condition.
from the weld surface. Care should be taken when applying heat to plastic to insure that the melting occurs only as desired. NOTE: Repairing a crack or hole DOES NOT return the plastic to its original strength, although most repairs are sufficient to insure a water tight section. Monitoring of the repair should be done for a short period after filling to insure that the repair has been done properly. If leaks cannot be prevented, the section should be replaced.
Water Freezing Prevention In freezing weather conditions, allowing the water in TrafFix Water-Wall to freeze to a solid mass of ice should not be allowed. If the temperature at the TrafFix Water-Wall site is expected to be at or below the freezing point of water, it is recommended that an additive be used to prevent the water in the TrafFix Water-Wall from freezing. -Common additives used to prevent water freezing currently used in work zone devices under the same category as the TrafFix Water-Wall.

Limitations and Warnings The TrafFix Devices TrafFix Water-Wall has been tested and passed all NCHRP-350 test criteria and received FHWA product acceptance letter HSA-10/B130 as a Longitudinal Barrier at Test Level 1 (TL-1), an acceptance letter HSA-10/WZ-224 as a Longitudinal Channelizing Device at Test Level 2 (TL-2), and an acceptance letter HSA-10/WZ-224 as a Barricade at Test Level 3 (TL-3).
Float Lid—Optional To indicate the water level in the TrafFix Water-Wall , a TrafFix Devices Float Lid can be used. The Float Lid consists of a lid and a green indicator. When the TrafFix Water-Wall is filled to the appropriate level, the green level indicator is popped up as shown in the figure below. When the TrafFix Water-Wall is not filled to the appropriate level, the green level indicator retracts into the barrier wall.
