Buy Fill Dirt in Sisters, OR

Oregon Rock Supply sells gravel and aggregate delivery in Sisters, OR to two kinds of buyers: contractors building pads and drives, and homeowners prepping beds and lawns. Both usually start with soil and base work before any decorative stone goes down.

The ground here is young volcanic country, and 3/4 minus is the base most of that work sits on.

Materials for Sisters Projects

Grading and bed prep come first on most Sisters lots, so the soil products carry the weight of the work. The ground around town is thin over hard rock in places and ashy in others, which means you often need to build soil up rather than dig into it.

Top Soil is screened loam for lawns, bed prep and finish grading. Screening matters here because local ground silts up and clods when it is wet.

Garden Soil is a garden blend for raised beds and vegetable plots where native material is too tight to plant into.

Fill Dirt is bulk structural fill for raising grade, backfilling and building up low spots before a base course goes on.

Base materials follow the soil work. 3/4 Minus, also called 3/4-0 or dense-graded base rock, is crushed rock graded 3/4 inch down to fines so it compacts and locks up under driveways, parking pads, shop floors and shed bases.

Quarry Run is raw rock straight from the pit face, not crushed or graded, and it goes down first to build up soft ground and raise grade.

For drainage, Drain Rock is washed round stone for French drains, footing drains, drywells and downspout runs. 3/4" Crushed Stone is angular rock with the fines screened out, used in drainage trenches, retaining wall backfill and construction entrances.

Sands and decorative stone round out a project. Washed Sand beds pipe and levels under slabs and flatwork, and 3/8" Natural Pea Gravel covers paths, dog runs and play areas with a smooth rounded stone.

Willamette River Rock is water-worn stone for decorative beds, borders and dry creek beds.

Ground and Conditions in Sisters

Across Central Oregon and the High Lava Plains, the ground is the youngest volcanic country in the state. You get young basalt with pumice, cinder and ash soils, and thin soil over hard rock along the rims.

The water driver in this part of the state is low rainfall, roughly 8 to 12 inches a year, and ground that drains very fast. Pumice and fractured basalt shed water instead of holding it.

That flips the usual problem. Instead of getting water away from a build, you often need to hold moisture long enough to compact.

Summer compaction normally needs added water.

Erosion comes from two directions: wind across bare pumice and ash, and short intense summer thunderstorms cutting channels in dry draws. Bare soil left through the season moves.

The working season is long and dry from late spring into autumn, cut short at both ends by hard frost. Cold clear winters bring wide day-to-night swings and repeated freeze-thaw.

Frost depth runs 12 to 18 inches below 4,000 feet and 24 inches at 4,000 feet and above, and Deschutes County points applicants at the state design criteria hub for the figure at a given site. That is a footing depth set by the building official.

What stone should I use for drainage in Sisters?

Drain Rock is the washed round stone for French drains, curtain drains, footing drains, drywells and downspout runs. It is washed and open so water moves through instead of sitting.

For drainage trenches and retaining wall backfill, 3/4" Crushed Stone is angular rock with the fines screened out. Both drain because the fines are gone.
