Concrete slab add

Post by greg1 » Fri Jun 08, 2018 12:01 am

What is the way to raise concrete floors? I know there are some self leveling compounds, but they are quite expensive. Is there a cheaper alternative? I need to add a couple of inches in one of the rooms.

Self levelers allow for up to 1" max I believe @ 6 sq ft per bag and $30-$40 per bag. Too expensive.

You can overlay concrete with at least 2" of new concrete. Anything less and you're looking at cracking and flaking issues.

What about some wood sleepers with 3/4" plywood over that?
