Q: H20 Dams, what are they & how do they work?
A: H20 Dams contain a super absorbent polymer (similar to what’s found in baby diapers and meat pads) that react and swell on contact with water.  Once activated (typically 5 minutes if there is enough water), the water is contained as a gel within the black fabric, thus acting as a barrier and containing or diverting water to prevent flooding.

Q: How do you activate them?
A: There are several options. Lay them in position and wait for the rain, spray with a hose, dunk them in a bucket of water, lay them in a puddle or place them in a water source like a stream.

Q: How long do H20 Dams last?
A: Un-activated- indefinite as long as kept dry, so store in a closed package until needed. Activated- If left in position, they can last for several months.

Q: Can I re-use them?
A: Once activated, H20 Dams will remain active until the water evaporates, typically taking a few weeks for complete evaporation. If left in position, they will shrink while
Evaporating and grow when re-exposed to water.

Q:  They seem to shrink, is that normal?
A:  Yes, as the water evaporates, they will get smaller. If complete evaporation is desired, store H20 Dams in a dry environment. Over several weeks, H20 Dams will shrink & become crunchy. Once re-exposed to water, they will swell again.

Q: Do I have to add water?
A: Depending on your situation, you may pre-activate them or let the weather activate them. H20 Dams can be placed in position and wait for water to arrive. If a current of water is expected, partially activating them is recommended so that they don’t float away. If building a retaining wall is desired, pre-soaking & stacking them is recommended.

Q: Can H20 Dams be used indoors and outdoors?
A: Yes they can, although they will be moist, so be careful when leaving them on floors that may get water damage.

Q: Can they protect against water higher than 3”?
A: Yes, you can stack them in a stager pattern to required height.
