Limestone screening, or stone dust, is ideal for large or small regrading and landscaping. Once compacted, limestone screening creates a hard surface that sheds water and inhibits the growth of weeds. For these reasons, It is used on baseball paths. Municipalities create and refurbish bicycle and hiking trails with limestone screening. They also use it to divert water away from structures and raise the grade of low-lying sections of roads, paths and driveways prone to flooding. Homeowners use it as a base for flagstone paths and for building gardens above grade.
Using a wheelbarrow and shovel, cover your work area with screening to a height of 3 inches above grade.
Rake until the surface is smooth, the center rounded, and the sides tapered.
Tamp so the top surface is compacted to 2 inches above grade and the sides taper to 1 inch above grade.
