We use this around our horse barn. Horses have stepped on ....I would think over time it will break down and need to be replaced.
They mostly block it.
Absolutely! I bought Quick Dam for this very reason. However, placing the product on the outside of the door prevents water from entering much more effectively. I live in FL and when the huge storms come through, water used to leak under the garage door and into the garage and owould run for towels. Since putting the product on the outside of the door, as mentioned above, really works!
Would not recommend - it will bust a hole and/or squeeze out the silica gel.
Approx 4”. You can stack theses if you need more height - also, Home Depot sells the Quick Dam sand bag (6 per package). I have used both successfully to keep water from entering my barn. I have even presoaked them prior to a heavy rain - but you don’t have too.
The only job for these water barriers is to soak up water -- indoors or outside. I use mine outside. The packaging shows a picture of barriers stacked on each other. I would not hesitate to use these barriers for the need you described.
Yes
The quick dam flood barrier will absorb the water. I use one inside my garage where the door meets the pavement. The driveway has a slight slope which causes all snow/ice melt or rain to run to the garage.
Yes. Make sure you let them dry out and then put them away...cannot leave out in sun....it will shorten their life.
You have to place them in a dry place, preferably in the sun. It takes a while for them to dry. Just ignore them and let them dry.
