Quick Dam Water Filled, Water Curb diverts flood water, 6.5in high x 10ft long, 1-Pack

Bought 4 of the 20 ft long ones, and several of the 10 foot long ones to placed on top of our breakwall which is a flat concrete surface (sealed concrete). Placed them, got up the next morning and two were in the yard having rolled off! Light breeze, 10 mph, no storms or high winds and no waves as the lake was calm. Drained them, stacked them as recommended by a company rep, left the cottage, coming back about 10 days later and they were scattered like dominoes in the grass yard, having rolled off the flat top of the breakwall, which is about as wide as a sidewalk. Two of them, a 20 ft and a 10 ft, had torn open at the seams and were laying flat...all the water had leaked out of them thru the tears. . We threw them away, emptied out the other ones by unscrewing the stopper, , rolled them up and stowed them in the shed. We are returning the unopned two 20 footers and one 10 footer. These MAY work if you are only using them to place in front of a closed garage door, but they do not work on top of a flat surface w/o something for them the "lean" up against to stop them from rolling. I contacted Amazon for a return adn then I contacted the company rep about it who suggested that our concrete breakwall may not be sealed and they recommend putting down a plastic sheet under the Quick Dams. Our breakwall is sealed, and a plastic sheet under these would have been like a slip and slide! They couldn't stay put in 10 mph breezes and with the plastic sheet probably would have slipped off as soon as we walked away. An expensive failed experiment. For the same amount of money that we paid for all of the Quick Dams we ordered, we could have brought in a load of large concrete formed blocks and hired the backhoe to place them on top of the breakwall...which is just what we have done.

Stopping rainstorm water from flowing under shop door.

used it once and only had to fill it half full with a garden hose to give it enough pressure to rediret the water across the driveway, so far so good. Next day I went to drain it and low and behold a nice split across the seam allowed me to forgo that simple task. It went from my driveway onto the garbage pile. Not impressed and a nice waste of $116 by the time I got it to my door.

works great

This product sits totally flat on the ground so there is no leakage under it. No more trying to lift, position and take away many sandbags. Completely diverts water away. We have one across our driveway and are so pleased we have purchased two smaller ones for in front of our garage. Emptying bags takes longer and this allows for being careful not to overflow our soak holes
