Keeping it Natural
Concrete subfloors can serve as the real floor. Concrete can be textured or colored for a unique and beautiful surface. Leaving concrete bare avoids all the resource usage and environmental impacts of wood, carpet or other flooring. It also lasts longer than carpet or tile.
Of course, skipping one layer of flooring also saves money, and may be healthier for your family. Concrete is easy to clean, has minimal volatile organic compounds, and it doesn't attract mold and other pollutants to your indoor environment.
It can also reduce energy costs. Because of the insulating properties of concrete, it is an ideal medium for radiant heat flooring, as well as passive solar heat gain.
These are some concrete examples of how to compensate for the potentially high environmental impact of concrete in construction. Be sure to seek out concrete with recycled content, minimize materials usage and take advantage of concrete floors.
