Level A Sloping Concrete Floor

As the underlying ground settles further the concrete slab will slope or sink in a particular direction making one side higher than the other.

Level a sloping concrete floor.

The average person can sense if a floor slopes 1 inch in 10 feet and sloping floors or sagging floors are often one of the warning signs that structural engineers look for when analyzing a house. Although most floors slope it is important to know how much and why. Slightly sloping floors which are common in older houses often worry homeowners who want to install new rigid floorings such as laminate ceramic tile or hardwood. To resurface an uneven concrete slab begin by laying a long straight 2x4 wooden rail across the concrete slab floor with one end positioned on the high point in the room.

However the prep work you do first often determines whether or not the project is a long term success. Slip shims under the low end of the 2x4 rail until it s perfectly level then use a scribing tool to transfer the unevenness of the floor onto the rail.
