Review on 1 Pack of Quick Dam Flood Barriers by Tom Roberts

Bought 4 20ft and about 10ft to place on our breakwater which is a flat concrete (sealed concrete) surface. Dressed up, got up the next morning and rolled back into the yard two o'clock! Light 10 mph breeze, no storms, strong winds and waves as the lake was calm. Dried them out, stacked them as recommended by the company representative, left the cottage, returned about 10 days later and they lay scattered like dominoes on the grass in the yard, rolling down the flat top of the breakwater, what about the height of 100 m corresponds to the width of the pavement. Two of them, a 20-foot and a 10-foot device, detached at the seams and lay flat. All the water flowed out of them through tears. . We threw them away, dumped the rest, unscrewed the cork, rolled it up and put it in the shed. We are returning two 20ft and one 10ft unopened. They CAN work if you just place them in front of a closed garage door, but they won't work on a flat surface without something to "lean" on to stop them from rolling. I contacted Revain for a refund and then contacted a company rep who suggested our concrete baffle could not be sealed and he recommended putting plastic sheeting under the Quick Dams. Our breakwater is sealed and the plastic sheeting underneath would be like slides! In 10 mph winds they couldn't stand still and the plastic sheeting would probably have slipped off once we started driving. Expensive failed experiment. For the same amount of money we paid for all the Quick Dams we ordered, we were able to bring in a load of large concrete form blocks and hire an excavator to place them on the breakwater. We did. .
