4 Pcs 6' × 6" Long Sand Bags for Flooding - Thickened Canvas Flood Protection Sandbag Tube with Elastic Band, Reusable Flood Rain Wind Barrier Sand Bag Tube for Door Window Flood Control

I used one 100 pound bag of course sand from home depot and it filled all 4 bags and once tied up the sand doesn't fall out of the bags

Very well made. They should sell a funnel made to fill them. There ya go. My flugel binder.

They are durable, however, they are kind of loose at the ends even after tying, so sand can fall out and cause a mess. You have to really tighten them. I bought a 50 pound bag of play sand from Lowe's for about $6 or $7 dollars and manually filled the bags with a plastic cup, but one 50 pound bag wasn't enough to fill all four, so I had to get a second bag of play sand, and I had some left over.

Easy to fill up and install

We buy these frequently to direct water on our property. Works great.

I got these one year ago. I've replaced a few because the threading was too weak and broke. Now it appears they've gone with a weaker fabric. I'm not real confident that this fanric will hold up to it's intended use. The threading still appears weak too.

I filled these with sand (using an improvised funnel) and placed them end-to-end (with an 8" overlap) along a 15 foot length of concrete, in an area prone to flooding during heavy rains. They held up and kept the area behind them dry through several strong storms.They do not sit very tall, but they can hold back at least 2 inches of water if they are fully packed and the water does not have much momentum behind it. You may need to add sandbags on top of this at the points where each segment overlaps the next.The green dye on the canvas did NOT leach or stain the concrete after sitting on it for several months in all kinds of conditions. I am very pleased with this product.

Use them in my garage to absorb & direct snow/water melting off my truck towards the drain.
