Dam to hold water

I know I have to make a dam around my water heater so in the event of a leak, water will be trapped enough to have the sensor go off. Do you have any recommendations for the dam?

Answer: 
Purchase a plastic or metal "drain pan" from any plumbing warehouse. You can type "water heater drain pan" in your search engine to see some examples. They cost from $15 -$50. Measure the diameter of your water heater before you go to store. If your water heater is already installed, just build a make-shift dam but make sure you use materials that are non-combustible and/or in accordance with manufacturer's recommendations. You can call your water heater manufacturer tech support to ask them what they recommend. Hint: In my personal opinion, it doesn't have to flood for these things to go off; it's OK if your make-shift dam leaks.
