Works great! Reusable, unlike most other similar products. I use it to contain about 6 inches of irrigation water every 2 weeks in AZ sun.

I researched many options in the marketplace and am very happy I chose this product. It handled Hurricane Matthew's attack on my home in Florida October 2016. The 24 feet long x 20 inches wide x 12 inches high barrier covered my standard 2-car garage with about 2 or 3 feet overlap on both sides. It was very easy to setup and fill by myself. You can make minor adjustments to the unit while less than half full. After that it becomes much more difficult alone. Think it through before filling. I highly recommend this product. Well made with durable materials. It should hold up for many years. Sand bags cheaper but are one time use option and much more difficult to stack and then remove after the storm.

Note to MFG: For the longer units it would be extremely helpful if you could add a 2 fill/drain port on both ends. It would make the draining and 'drying' much faster after the storm. This is not a complaint and is overall a minor issue. I would definitely purchase again.

Enjoy these Hydrobarriers - We have a 12' foot and 2 6' ones and they do well in a storm. One came with a small hole or so it seemed because we could see a leak. These are very easy to fill and and much nicer than traditional sandbags. Hard to store - if you live in a humid area - we had mold on one this summer, but otherwise I highly recommend as a barrier method.

best for level, straight ground are but overall worked to prevent flooding in my yard

Saved my garage floor! First solution that worked in six years. The volume of water overwhelmed a very expensive drain system but not this product! The weight of the water inside the barrier keeps it in place, and directs the flow to the lowest exit from the protected area. These Work!!
