<div align=justify>Wood over concrete can be done. For the longest time, homeowners were warned that wide plank wood floors installed over concrete would result in moisture problems. But that’s not so anymore. A concrete sub-floor is no reason to deny your home beautiful wood floors.

It is true that wood is affected by climate change: wood fibers expand and contract with fluctuations in relative humidity. However, this movement and the resulting moisture problems can be controlled with proper installation techniques and the use of high quality wood products.

If you’re going to be installing over concrete, it becomes even more critical that you understand what part of the tree the boards are cut from and the manner in which the boards were processed; both of these factors are vital to your overall satisfaction with the floor. Wood cut from the center of a tree contains a higher percentage of vertical grain which makes it less susceptible to movement and thus a higher quality material.

Before you embark on this installation process, there are certain rules of thumb to manage moisture and ensure the stability of the wood:

1. Be sure the wood supplier has properly dried the wood. 
2. Let the wood acclimate in the home or business for 7-10 days. 
3. During acclimation in your home or business, keep relative humidity at 45 percent. 
4. Make sure the wood flooring has proper stress reliefs (These ridges on the underside of the wood relieve tension in wood, reduces board movement, and provides a greater glue surface).

There are two options for installation of wide plank wood floors. Both options are driven by the height allowance between the slab and door. To determine height, measure the distance from the top of slab to the bottom of the exterior door or measure the transition to other flooring surfaces. Check accuracy by swinging door completely in both directions.

Here are some step-by-step installation guidelines once you know the height allowance:

Option One: Gluing directly to concrete -- 1/2 to 3/4 inch height allowance

Using an adhesive product, spread one layer of adhesive onto the concrete per manufacturer’s instructions and place your planks, milled to 1/2 to 3/4 inch thickness directly onto the adhesive. Allow 12 hours drying time before finishing your floors.

Option Two-A: Concrete slab with plywood sub-floor -- 1 inch height allowance

Place a layer of 6mm polyethylene onto the concrete as your moisture barrier. Using a fastening tool, shoot concrete nails into 1/2 inch plywood to apply directly onto concrete. Install Wide Plank Floors, milled to 1/2 inch thickness by blind nailing and gluing.

Option Two-B: Concrete slab with plywood sub-floor -- 1 1/2 inches or more height allowance

Lay down 3/4 inch plywood and then follow the directions above.

The cost associated with both options for installing wood over concrete is similar. However, due to the cost of the adhesives, it can be slightly cheaper to use the plywood method.

It’s also possible to install floors over concrete slabs with radiant heat. The installation process calls for using a floating plywood sub-floor. </div>
