Recently, we covered the topic of wet floodproofing your facility. Now we're going to explore the decidedly less messy affair of dry floodproofing. Just as is the case with that other technique, computer maintenance management software can prove extremely useful for all your preparation needs.
Wet floodproofing involves letting water through the basement of your facility. Dry floodproofing takes the opposite tack, with your main goal being trying to keep waters out of your building. According to the Federal Emergency Management Agency, you'll want to implement dry floodproofing methods when a building is only going to be exposed to floods of a limited duration and depth. Typically, this means no more than few hours and no more than a few feet. Any higher and longer, and you may want to pursue other courses of action, including wet floodproofing and evacuation.
If you are going to dry floodproof, you'll have plenty to do before a storm hits. Make sure you enter every last step into a checklist on your CMMS, and begin preparations before the last minute.
There are a number of key elements to dry floodproofing, all of which are meant to create a seal to keep water from entering your facility. Flood shields around the perimeter of a facility, sealant for cracks around doors and windows and backflow valves are all worth installing. The shields and sealants are only a portion of the means by which you want to create a protective barrier. You may also want to install small walls around at- or below-grade windows, or even consider bricking over windows in extreme cases.
While you may have installed a variety of techniques to keep water out, you're not likely going to be 100 percent successful, thanks to small openings in your building. Backflow valves and internal drainage systems are meant to prevent or remove water that may flood via fissures or blocked pipes.
Getting to work
As you can see, there's plenty of work to be done when it comes to dry floodproofing. If you have a CMMS, you can use it to keep track of the many maintenance procedures required to implement a dry plan. It's best to create that checklist well in advance of any potential storm, so that you can easily start to prepare once flood season begins. Just be sure there's enough time between the alert and the beginning of a flood before you attempt any dry proofing. Otherwise, start proofing before any mention of a flood. If not, you may be left out to dry - or, rather, get wet.
