Just to come at this from another angle, I went a slightly different way: 15 years in my house, water in the basement twice (although none since since regrading, new gutters, other mitigation steps). However, Murphy's law prevails. When I finished the room, the intention was to make it "recoverable" should a flooding occur. Instead of Dricore, I went with those 2' x 2' interlocking foam pads sold for kids playroom/work areas - you can find them at the Big Box stores. Over that went the carpet (in my case, I went with a bound remnant that fit the exact dimensions of the room). The idea is that in the event of water, I can roll up the rug, pull up the squares, and let everything dry out with minimal loss. Meanwhile, the closed cell foam provides a nice soft cushion for the rug, makes it "feel" warmer, and was far cheaper than the Dricore. YMMV.
