Crushed Stone, Sand and Gravel in Seward, AK

Alaska Rock Supply handles gravel and aggregate delivery in Seward, AK, for drives, pads and drainage work. If you are building a driveway or setting a pad, the material under it is D-1 base course.

Across the Cook Inlet basin, from the Anchorage bowl to the Kenai, ground water moves fast through outwash gravel until it hits the silty clay below. That is the ground your base sits on.

Materials for Seward Projects

It is the compacted layer under driveways, parking pads, shed and building pads, and flatwork.

C-1 is the coarser of the two gradings, for where a deeper structural layer is wanted.

Above the base, driveway gravel surfaces an existing drive or tops a finished base course. Pit run, also called bank run or unscreened gravel, is not a crushed product.

It comes out of the pit as it is and goes down as bulk fill to raise low ground before a base course goes over it.

3/4 inch crushed stone, or 3/4 minus, covers drive surfacing and trench backfill.

3/8 inch crushed stone beds pavers and tops a walkway.

For water, drain rock is clean washed stone with the fines taken out. It goes in French drains, foundation perimeter drains, drywells and downspout runs, and water moves through it instead of sitting.

Screened sand beds pipe and flatwork and backfills where a clean fine material is wanted. Mason sand is the finest washed sand, for mortar and block work and a smooth paver setting bed.

Top soil is the growing layer for lawns and beds, and garden soil is blended for raised beds and vegetable gardens.

Riprap, also called armor rock, is bank and shoreline armour and steep slope protection. Large river rock and river rock are rounded and decorative, for dry creek beds and borders, and rounded stone does not lock together.

Ground and Conditions in Seward

Start with where the water goes. Outwash sand and gravel takes water fast until it reaches the silty clay beneath, and then it stops.

Low ground and the toes of slopes hold water that has nowhere to go.

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.

Erosion follows the same water. Bank cutting along the glacial rivers and creeks peaks at breakup, bluffs retreat where coarse outwash sits on clay, and rill cutting crosses bare graded ground before it is covered.

Winters here 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.
