Riprap, Stone and Soil Delivery in Healy, AK

What does a bank, swale or washed out slope in Healy actually need? For gravel and aggregate delivery in Healy, AK, the answer usually starts coarse.

Alaska Rock Supply delivers bulk material by the ton, from riprap for armored banks down to D-1 base course for the compacted layer under a pad.

This is wind laid silt over ice rich ground, and silt erodes fast once the cover is off. That shapes what you order here.

Materials for Healy Projects

Coarse angular stone is what holds a slope, a swale or a bank in place. Rounded stone does not lock together, so it is not slope armour.

Start at the coarse end and work down to the fines you need for bedding and surfacing.

Riprap, also called armor rock, is bank and shoreline armour and steep slope protection. Section 611 grades it in Classes I, II and III by the weight of the individual stone, and it rules out rounded boulders and cobbles on slopes steeper than 2:1.

#4 crushed stone is a coarse clean stone, roughly 1 1/2 inch, for heavy drainage and erosion work. It is the open graded end of the crushed sizes, so water moves through the void space instead of pooling.

Railroad ballast is coarse angular stone for track beds, heavy equipment pads and very wet ground where a large open stone is wanted. In saturated silt, that open structure is what keeps the surface from pumping.

Drain rock, also called washed rock or 3/4 clean, has the fines taken out. It goes in French drains, foundation perimeter drains, drywells and downspout runs.

Where the ground looks free draining but permafrost under the silt stops water moving down, that clean stone is the layer that gives water somewhere to go.

Below the coarse work, D-1 base course is the compacted layer for driveways, parking pads, shed and building pads, and the layer under flatwork. C-1 base course is the coarser of the two Alaska base course gradings in Table 703-2, used where a deeper structural layer is wanted.

For bedding and joints, screened sand also goes by fill sand or bedding sand, and it beds pipe and flatwork.

On the growing side, top soil is the layer for lawns, beds and grade repair.

Ground and Conditions in Healy

The working season between breakup and freeze-up is short, and frozen ground stops compaction for most of the year. Ground thawing in spring is the worst of both.

That is why timing a delivery matters as much as the material itself.

Across the Tanana valley and the Interior uplands, permafrost under the silt stops water moving down. Ground that looks free draining holds it near the surface, and the whole winter snowpack comes off in a short breakup.

Thaw settlement, not drainage alone, is what wrecks a pad built on ice rich ground. Bare silt also erodes very easily once the cover is off, so gully cutting and thaw slumping follow any cut into ice rich ground.

Breakup flooding and ice jams on the Tanana and its tributaries drive the erosion work here. That is the case for coarse armour on exposed banks and clean open stone where water needs to move.

No statewide frost figure applies, and footing depth is set by the local building official. On ice rich ground the governing question is keeping the ground frozen rather than founding below a frost line.
