Watching the water levels rise just yards away from their Lafayette Parish, La., home, Shannon and Alphonse Breaux expected the worst.
The devastation in the Houston area had looked like a precursor of what was coming their way. And the approaching storms seemed reminiscent of the floods that, just a year ago, destroyed their home and forced them into a camper for 10 months.
"We were like, 'There's no way in hell we're going through what we went through last year,'" Shannon tells CNBC Make It.
Despite the fact that they already pay for flood insurance, the couple decided to be more proactive in preparing for Hurricane Harvey. They turned to the AquaDam, an increasingly popular invention built from re-fillable tubing that is designed to keep areas protected from flood water.
They spent $7,000 on the dam itself and about $3,000 on dirt, pumps, and other supplies. In 12 hours, the Breaux home had a 30-inch fortification in place.
