Laminate or vinyl on a concrete basement floor?
I would suggest Allure product for your situation. But use the original, its easier to install. If you need to level the floor try a product (it in a red colored bag, 50lbs), called Levelquick. Self-seeking leveler, but make sure use a wood block or something if you need to "stop" it because it will just keep going and going. (oh, Allure is found in Home Depot) It's water-proof, durable, resilient too. Good for a busy family. Read directions to install. No underlayment needed, do not glue it, it's a floating floor. Make sure you leave about 1/8" space near walls, etc, otherwise it will buckle or separate. Halstead makes it for Trafficmaster, look for Customer Service number for further questions.
