Adjustments may be necessary as landscaping can alter water flow.Barriers should be stacked higher than water level for stability and to prevent them from floating away.Barriers are flexible and can be curved or wrapped.Barriers have a dual chamber, place wider edge towards water smaller wedge away from water to prevent rolling out of position.Pre-Soaking is recommended prior to stacking or if heavy rain or water flow is expected.Staining may occur in instances where the surface is porous or unfinished cement is present. Remove from area when no longer needed.Porous surfaces like unfinished cement cause excessive seepage, since they are both trying to absorb water. Plastic barrier film in between, may help.For use in the winter/snow months, make sure they are fully activated before freezing temperatures occur to assure maximum protection when the snow is melting. We do not recommend moving them while frozen to prevent any tearing of the outer material. Also, salt on the roads should not come in contact with Quick Dams. To help, pre-activate Quick Dams with water then wrap plastic under over the top to prevent the salt from making contact.Do NOT use around salt water, lime or calcium. These will cause the inner absorbent to release the water deflate the product making it useless.Flood Barriers will not fully activate unless enough water is present.Once activated by water they can be used as a barrier against other oils chemicals.Leave in place for 3-6 months of ongoing protection. Shrinking will occur as they dry out, but they will swell again once re-exposed to water.Length of time to dry out varies on climate. Average is about 3 months as higher humidity levels tend to take longer.Once completely dry, they will feel crunchy and ready for reactivation. Smooth the contents to evenly distribute the super absorbent polymers.Direct sunlight causes the product to degrade at a rapid pace, which will result in the product feeling slimy.Do NOT cut. The inner contents will be exposed and will make the product unusable.Storage Shelf LifeBarriers unused, have a 5+ year shelf life.Store in sealed bag for maximum term.Keep on hand for immediate deployment.How to Dispose Throw Features Water Activated Flood Barriers, Rated #1 in Flood Control Grows to 3.5in high in minutes, just get them wet Long, flexible design creates all sorts of shapes.
