The challenge of remodeling a basement often revolves around the cement floor and whether or not dampness is an issue. In the past, to lay interlocking laminate flooring in a basement, a subfloor of plywood was needed to provide a barrier between the cement and new flooring material. Today, there's a new interlocking underlayment that can be used called Delta® FL. The underlayment is a thin, 7/8-inch-high dimpled plastic sheeting that protects the flooring laminate from problems caused by damp concrete, allowing the dimpled underside to handle minor leaks other floor treatments cannot.
The underlayment costs .51 cents a square foot. To lay the underlayment and laminate floor in a 10-by-12-foot room, a contractor will charge $815 for the labor and material. You can buy the material for $560 and do it yourself and save 31 percent.
To find out if a cement floor is damp, conduct this simple test: Tape a piece of aluminum foil to the floor and wait a few weeks to see if an accumulation of moisture appears on the inside of the foil when it is removed. If it's dry, there's a good chance the cement doesn't hold moisture; if there are beads of moisture, consider painting the cement instead of finishing the floor.
