4. Flood water level or maximum water barrier opening E Extra barrier length We recommend a minimum extra length of up to 50 depending on the flood water level In addition every time the Water Gate is abruptly lifted against a wall a space is created and water will infiltrate from the corner We strongly recommend placing one or more sandbags on that corner The water pressure exerted on the Water Gate stretches the fabric thus creating a wider opening promoting infiltration in that corner PROTECTING AN ENTRANCE The Water Gate is not designed to be installed in a door frame For adequate protection you must go around the door and lift up the ends of the Water Gate on each side of the wall This type of protection requires extensive barrier length based on a calculation of the exterior Water Gate contour Using Water Gate for your doors will give you better protection as you will be able to pump up any water infiltrations before they reach your door You will also maintain access to the exits of your buildings at all times If you decide to only protect the entrances instead of all the walls of your building make sure that no water can seep in through the walls The opposite photograph shows an air hole in a brick wall Such holes are found on all insulated brick walls Make sure you fill in these small holes before the flood and clear them again after the flood ADHERENCE THE WATER GATE WHEN INSTALLED ON A SMOOTH S

12. URFACE Usually none of these precautions are necessary but we believe that if you use one or two of these methods at the same time it would be impossible for the Water Gate not to stay in place The water pressure exerted on the fabric at the bottom of the Water Gate is 4 times that of the pressure exerted on the side see WATER HOLDING BACK WATER which is more than sufficient to hold down the Water Gate on most surfaces found outdoors asphalt lawn gravel concrete paving blocks etc However some exceptionally smooth surfaces such as tarred asphalt or polished cement require particular attention What happens with this type of surface is that the water stays trapped between the fabric at the bottom of the barrier and the smooth surface causing loss of surface tension The result is similar HYDROPLANING when driving with completely worn down tires It is very important to understand what it takes to ensure that the Water Gate adheres properly to the ground AT NO TIME SHOULD WATER ACCUMULATE UNDERNEATH THE WATER GATE When deployed on regular asphalt the Water Gate is very safe due to the presence of small cracks in the asphalt which enables the water to drain through to the back of the Water Gate 1 12 If Water Gate has to be installed on an EXTREMELY SMOOTH surface simply take some additional precautions as shown below Apply a food substance such as molasses caramel or even bread dough underneath the ballas
13. Unbalanced water pressure due to the flood When you install one or more water pumps it is important to leave enough space between the building and the back of the barrier to allow you to move freely and regularly check the pumps Make sure your pumps have enough power to pump up all the water flowing under the Water Gate and prevent this water from reaching the wall of the building 14 is hard to determine number of pumps needed and their required capacity but we do recommend having minimum of 2 pumps one for the basement and the other to put between the wall of the building and the protective dam For water getting through your dam you will need a pump with a capacity of 1 2 gal to 3 75 gal per min for each linear yard of dam The required pump capacity mainly depends on the type of ground involved and where the dam is installed FOLDING UP THE WATER GATE FOR STORAGE It is very important to fold each Water Gate as it should be Folding the Water Gate model WL 1430 illustrated 2 Using a stick make sure all partitions are smoothed out to enable you to fold up the Water Gate tightly so that it can be easily inserted in its bag once rolled up 1 After cleaning and drying the Water Gate stretch it out on a large flat surface 4 Start folding from the back so that the ballast weights will be positioned in the middle and Water Gate to it if need be under the Water Gate Use the folds already appearing on t

Used on winding roads but in the opposite direction as that shown in the previous figure If the curve is somewhat pronounced the rounded erection of the Water Gate must be completely unfolded Such particular attention is required to make sure that the Water Gate is not stretched and to prevent water infiltrations from underneath the steel plates which will tend to compress lift up BACK OF WATER GATE 1 Completely unfold the Water Gate 2 Curve the Water Gate as needed making sure the back of the Water Gate is not stretched Place a second series of ballast weights 4 Sandbags can also be used to close off along the entire length to prevent water the spaces or folds formed by the infiltrations Water Gate ballast weights 10 HOW THE ENDS THE WATER GATES SHOULD PLACED The ends of the Water Gates are not closed off so they must rise up higher than the level of the flood Since the water flows freely inside the Water Gates the front and or back sides of the Water Gates must be higher than the maximum flood water level The 3 photographs below different options for sealing off the ends Extra Water Gate length will also provide maximum safety Tie off straps where necessary to hold up on walls a a 2 moon 0 i 4 z T n am n Weight against structure to hold in place D

Water Gate remains in a stream for a month or longer a light coat of silt will form inside on the fabric at the bottom of the immersed Water Gate After four months only 50 of the fabric will remain visible due to the thickness of the silt Will the Water Gate withstand parallel water flow Parallel water flow is not a problem In the example below there was more water flowing than the Water Gate intended to withstand and the current was swift In the same trail with lots of parallel flowing water we attempted to damage the Water Gate with wood fragments Our testing process was rigorous but did not result in any damage to the Water Gate 26 What about leaks from Water Gate system No flood control system is 100 leak proof Even if a system were completely watertight there would be leaks through the ground from waste pipes in addition to rainwater falling on the part of the ground that you are trying to protect Water leaking through the Water Gate generally flows under the Water Gate Leaks occur because of the unevenness of different surfaces However the more the Water Gate barrier fills up with water the more water tight it becomes the water barrier is laid down on a regular asphalt surface with 4 10 cm of retained water the size of the leaks can be around 1 Gal min linear 3 ft However if the barrier retains 20 in 50 cm of water only about 1 2 Gal min 3 ft will leak from it Your emergency plan sho

29. t weights and along the entire length This substance will fill in the spaces between the bumps on your surface asphalt paving blocks etc and will also stick very well to the fabric of the barrier This process is ideal to eliminate water infiltrations and also improves adherence This efficient technique is also environmentally safe If theWater Gate is installed on a lawn you can make trench and bury the front part or ballast weights of the barrier Place stakes at the back of the Water Gate at a reasonable distance 1 to 3 meters 3 to 10 feet or even have the sides of automobiles rest against the back of the Water Gate This technique ensures that the Water Gate will not slip Should the Water Gate begin to slip it would gently be stopped by the stakes posts or automobiles and would hold back the flood without damaging anything The Water Gate can be installed fairly easily even in high wind The wind s strength isn t the ground Everything higher up that gets taken away by the wind ends up on the ground and eventually comes to a standstill Since the water barrier gets unrolled on the ground it is less exposed to the wind than objects further up The Water Gate can easily be kept on the ground in very strong wind however some additional precautions do have to be taken Although the wind is less strong on the ground a vacuum can be created on top of the barrier and cause it to lift up If possible to mini
