Bedding Materials
Bedding
Bedding is the layer of clean stone or sand you place under a pipe, tank, or paver to give it a flat, solid base. The pieces are small and well-graded, so they fill in low spots and let water drain instead of holding it. Common bedding runs from concrete sand up through 1-inch crushed stone, depending on the pipe size and the trench.
The right pick depends on what you're setting. For a 4-inch sewer line, #57 or #67 stone is the usual choice, and the spec comes from ASTM D2321 for buried pipe. For pavers or a septic tank, concrete sand or a clean bedding sand goes down first. Price runs low because bedding is mostly plain crushed rock or sand with no color or polish added.

What people use it for
How to choose within bedding
Around a pipe
Clean washed stone around the pipe, sized so the pipe never rests on a sharp point. #57 stone is the workhorse.
Under a paver
A coarse sand or fine screening levels flat and compacts uniform. Don't bed pavers in play sand — the joints move.
Behind a wall
Clean stone against the back face lets water fall away instead of pooling against the wall.
