I recently poured a 16x40' slab for a foundation I am building and am currently working on leveling my yard. I need to know what is suggested to level my yard so that water doesn't run underneath the slab. Do I slope away from the slab or is this something that I don't really need to worry about. I am trying to level my entire backyard, and really don't have alot of room for sloping, but I figured if it was gradual that the water wouldn't pool up in that are.
You don't say where you are from but even assuming you are in a warm climate it is always proper practice to slope away from the slab to prevent eventual erosion. If slope is not possible you can always install a french drain on the perimeter. If you had some pics, they would help.
