the floor is concrete at the moment, but we cant have them far off the ground. can the boards go straight onto the concrete?
The best way to do walls or floors in the basement is to first install treated strips of wood,then add a thin type of insulated board between them to reduce moisture.
Moisture is the big issue. Wood floors over concrete can be either glued down, or floated. A glued down floor is self explanatory. A floating floor is laid over a layer of moisture resistant foam, and held in place by virtue of its own weight and shoe molding around the baseboards. A good flooring store will come to your house and measure the moisture in the concrete with a moisture meter before selling you any product.
