CONCRETE FLOORS & FOUNDATION
A proper foundation does more than just hold a house above ground. Building foundations also keep out moisture, insulates against the cold, and resists movement of the earth around it.
A concrete floor is extremely strong and durable, and if it is properly installed and maintained, it can last for as long as you own the house. And the design options are remarkably diverse. But concrete is also very hard and cold underfoot, and it is a practical choice only where there is an existing concrete slab, such as in homes with slab-on-grade foundations, or in the basements of homes built over basement foundations. Since these floors on "on-grade"directly contacting the soil they can be susceptible to moisture migrating up from the ground into the living space.
Concrete flooring begins with a structural concrete pad that is by nature extremely strong and durable, which is why it is so popular for hard-working commercial areas, such as garages and warehouses.
Concrete has similar virtues when used as a residential flooring material. It is difficult to damage, and high heels, furniture legs, and pet claws won't scratch the surface.
