ok

We now have two of these for an alternative to sandbags. Quick to fill up. Drain by siphon into our soak hole grate. You need to have a plan for emptying these if no suitable drain close. A garden hose siphon works for us.

To stop water flowing into my patio , from neighbours over flowing water tank

My wife and I have used these water-inflatable heavy-gauge vinyl dams to prevent excess water from a slope from flooding our crawlspace, coming in through cracks in our foundation. Bottom line - these things are great; they're easy to fill (even without the recommended hose attachment), they fill fairly quickly from a standard hose, and they're relatively durable (these ones lasted 2 years, even out in the sun for multiple months at a time, before cracking from old age). On that last note however, regarding my "relatively durable" comment - our latest replacement barriers have met their match against a raccoon whom I'll call "Chompy." One late evening, my wife and I were awoken by sloshing sounds coming from outside our window where we had placed the Hydrabarriers. We thought they were raccoons and thought nothing of it. To our surprise, Chompy had assumed three of our Hydrabarriers were either a giant sausage or some sort of animal waterbed, and had left multiple two-fang bite marks and rips all along our barriers. And while patches were thoughtfully included by the manufacturer, they obviously never considered that we would need more than one per barrier to cover Chompy's Evening (Hydrabarrier) Chompfest. At a price of roughly $1/patch, it's worth it to patch the barriers, but for now while Chompy is resident in the area, I'm going to transition to the gel-based WaterDam products. At least if Chompy comes back, he'll get a mouthful of gel and polyester mesh.

I liked the fact that they are reusable, and I don't have to wait months for them to dry out. Easy to use and stayed in place.
