3/8 Inch Crushed Stone and Bulk Aggregates for Moose Pass, AK

Alaska Rock Supply handles gravel and aggregate delivery in Moose Pass, AK, by the ton or by the yard. D-1 base course is the Alaska base grading most drives, pads and flatwork start from here.

This page covers the sizes that do the work around Moose Pass, from clean washed stone for drainage to the fine crushed sizes that bed pavers.

Materials for Moose Pass Projects

Washed stone is the material to know for water around a building. Drain rock, also called washed rock or 3/4 clean, has the fines taken out so water moves through it instead of sitting.

Use Drain Rock for French drains, foundation perimeter drains, drywells and downspout runs. A graded drainage layer of the same clean stone is specified in Alaska as a filter blanket.

Clean drainage stone also comes by inch size. 3/4" Crushed Stone works for trench backfill and general use, and #57 Stone is a clean open graded stone about 3/4 inch for drainage and concrete work.

Where the opening is finer, #67 Stone runs a little smaller than #57 for drainage and bedding. #4 Crushed Stone is the coarse clean option, roughly 1 1/2 inch, for heavy drainage and erosion work.

Below the washed sizes sits the base course family.

Under a pad, Pit Run is unscreened gravel straight from the pit, used to build up low ground before a base course goes over it. It is not a crushed product.

For surfacing, Driveway Gravel tops a finished base course, and Walkway Gravel is a finer material that packs underfoot on garden paths.

The fine end covers bedding and joints. Stone Screenings are the crusher fines that pass the finest screen, used under pavers and as a packing top for a path.

3/8" Crushed Stone beds pavers and tops a walkway, and #8 Crushed Stone is a small clean stone, roughly 3/8 inch, for fine drainage and paver bedding.

#89 Crushed Stone is finer still, for paver joints and thin bedding layers. Screened Sand, also called fill sand or bedding sand, beds pipe and flatwork, and Alaska specifies a sand layer over subgrade as a sand blanket.

Mason Sand is the finest washed sand, for mortar, brick and block work and a smooth paver setting bed. For grade work, Fill Dirt raises low ground and builds up a pad, and selected material and structural fill are the Alaska terms for engineered fill free of muck, roots and sod.

Top Soil is the growing layer for lawns, beds and grade repair. Garden Soil is a blended planting soil for raised beds and vegetable gardens.

Rounded stone has its own uses. Riprap, also called armor rock, is bank and shoreline armour graded by stone weight, and rounded boulders do not belong on steep slopes.

Large River Rock suits dry creek beds and decorative edging, and River Rock covers beds and borders where nothing has to compact.

3/8" Natural Pea Gravel is rounded pea sized gravel for paths, dog runs, play areas and pipe bedding. Railroad Ballast is coarse angular stone for track beds, equipment pads and very wet ground.

Shredded Mulch dresses beds, tree rings and slopes as a surface layer, not a structural one.

Ground and Conditions in Moose Pass

Across the Cook Inlet basin, from the Anchorage bowl to the Kenai, ground runs in two layers that behave in opposite ways. Coarse outwash sand and gravel sits at the surface over silty clay and clayey silt laid down in a glacial marine setting.

The outwash gravel takes water fast until it reaches the clay beneath, and then it stops. Low ground and the toes of slopes hold water that has nowhere to go.

Spring breakup delivers the whole winter's snow in a few weeks onto ground that is still partly frozen. Thawing ground in April will not compact, and neither will the clay once it is wet.

Base, drive and hardscape work runs from breakup in spring to freeze-up in autumn. Winters are hard with a long shoulder season at each end, so the ground cycles through freeze and thaw rather than freezing once and staying frozen.

That cycling is what lifts flatwork and heaves a gravel drive built too thin. Bank cutting along the glacial rivers and creeks peaks at breakup, and rill cutting crosses bare graded ground before it is covered.

Anchorage publishes 42 inches for a warm foundation and 60 inches for a cold one in its local amendments to the residential code. Outside the municipality the local building official sets footing depth.
