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.
Level a sloping concrete floor.
The best method for leveling a sloped patio or porch floor is to pour a layer of self leveling concrete on the surface of the existing concrete.
Regular wear and tear severe fluctuating weather conditions and improperly preparing the ground before a concrete pour can result in a sloping concrete slab.
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.
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.
Although most floors slope it is important to know how much and why.
