Concrete sleeper system for condo hardwood floor.

The national wood flooring association recommends two choices in sub flooring systems for concrete installations. Treated plywood to the concrete with concrete screws spaced every 16 in. Set out the sleepers along the perimeter of the room and in their approximate locations across the rest of the floor cutting them to length as necessary. Moisture can cause floors to warp and provide a breeding ground for mold.

I would like to build a sleeper system to make the floor level to the rest of the house. Plywood on slab begin by covering the slab with a vapor retarder. Use a minimum of two layers 3 8 10 mm cd exposure 1 plywood subfloor panels cdx in 4 x 8 sheets. Plank flooring plank flooring four inches and wider requires either the plywood on slab system or the sleeper system topped with a minimum of 5 8 inch thick plywood or osb.

Lay 6 mil polyethylene sheeting over the concrete to minimize moisture migration from the concrete up into the wood flooring. It is approximately 5 in below the rest of the house. Snap chalklines to help you position the sleepers. Alternatively screw rows of treated 1x4s to the concrete 16 in.

Subfloor sleeper are used in basements to protect certain types of flooring such as laminate hardwood and carpet. Either subfloor system is satisfactory for three quarter inch flooring. Sleeper system nailed subfloor to concrete nailing subfloor directly to concrete most recently the most popular method of installing solid 3 4 hardwood floors on concrete was a plywood subfloor attached to the slab. Most basements have concrete floors which have the potential to draw moisture.

So happy its been of use to soooo many folks out there. This may be as simple as a 6 mil polyethylene plastic covering 100 percent of the concrete and brought up all walls then trimmed after the floor has been installed. My concern is how to deal with any moisture coming up from the slab. I intend to put in 3 4 hardwood floors.

Starting with a 1 4 inch gap along the walls mark the sheet with a felt marker at 16 inch intervals. That part of the house is on concrete slab. I have a sunken living room part of the design.
