Fixing the grade around your house will depend on a few things.
1) How far down has it sunk? Is it just a few inches? Or is it more?
If it is just a few inches I would add some topsoil and the compact it really well.
If it is closer to a foot I would investigate why the grade started falling first.
2) Why has it sunk? Is your home newer, say 2-5 years old, or is it older?
With newer homes the soil sometimes is not compacted properly, this means that over the years it starts to settle lower around the house.
If your house is older, you may be looking at whole different problem
3) Is it just in one area or around the whole house?
If its located just in one area it mean be that it just settled that way, but if its the whole house you may have a different problem.
I hope this helps
