Hello pdayton and thank you for joining The Community.  We are glad that you are here. 


Engineered hardwood flooring can be installed on, above, or below-grade.  Several issues must be addressed before installing engineered flooring over a concrete subfloor. 


1. The concrete subfloor must be clean, flat, dry, and structurally sound. 


2. The slab must be cured for a minimum of 30 days.


3. Concrete slabs should be of high compressive strength and constructed to prevent groundwater from permeating the concrete for below-grade flooring installation.  The moisture content for concrete subfloors registered after a calcium chloride test should not be greater than 3 pounds per 1000 square feet of area.


4. Grind the high spots or use a Portland-cement-based leveling material (minimum compressive strength 3000 psi) to fill all low spots. Follow the leveling compound manufacturer’s instruction. Leveling compounds must be allowed to thoroughly cure and dry prior to installation of wood flooring.


5. NOTE: 6 mil polyethylene is required over concrete type subfloors for floating floor installation whether on grade or below grade.


You can find additional information as well as the Floating Floor Installation Guidelines starting on Page 5.


Best wishes on your project.
