Pretend I have just a square house on a flat lawn, plenty of room on every side. Assume there's already grass planted on the yard all the way up to the house. I want to change the grade of the yard from flat to having that minimum 2% grade or whatever it was.

Can this be, basically, just a process of pouring clay soil around the house and packing it down, then planting grass over that?

Or is it necessarily, even in the simplest case, a more complex job than that?

I'm thinking about whether to try to DIY some basic yard grading, basically to get rid of any "dips" in the soil around my foundation. This is to help with some problems I have with some moisture appearing in my basement in heavy rains. I'd love it if I could do this by basically just pouring soil into and around the dippy areas and packing that down. There are a couple of places where an obstruction might change what I need to do (most annoying being a gas meter) but for now I just want to think about how the simplest case works and work from there.

I am serious about drainage around my house, in part due to the fact the house insurance does not cover overland flooding (water entering the house from outside).

The methods to resolve drainage problems can be quite inexpensive if the house has some slope in at least one direction.

Some caveats:

  • as blacksmith37 noted soil should not touch brick, siding or even the parging so commonly seen on poured foundations as cosmetic touch

  • water has to go somewhere: if your house is lower than other features or houses it's coming your way no matter what

  • grass needs to be removed to get the grading right. For drainage purposes it absorbs water and slows down where it is flowing to

For your example house your steps would be:

  • determine where water naturally flows to due to existing grade
  • roll back the grass around the house with a sod cutter and water to keep it fresh
  • add soil at the foundation but not touching the parging or brick or siding or sill plate until next to house is a little bit higher than the rest of the area
  • compact soil if very loose
  • buy some 4" perforated drain pipe with sleeve
  • dig a trench in the soil about 6" wide and 6" deep which follows the grade that goes away from the house. You want the water as far away as possible from the house, 20' or more
  • put the drain pipe with sleeve in the trench and backfill with soil
  • roll the grass back and use pressure to make sure it contacts the soil
  • water it in and watch where the water goes
