Order Type A Gravel and Crushed Stone in Hancock County, ME
Maine Rock Supply handles gravel, stone and aggregate delivery in Hancock County, ME. Start with the calculator on any product page to size the load, then pick your material.
Type A gravel is the Maine base course, and it is where most driveway and pad work begins.
This is DownEast and Acadia country, where shallow soil over ledge and wide stretches of bog and peat leave water sitting on the surface. The outwash barrens drain the other way and wash out unbound surfaces.
Material choice follows the ground.

Materials delivered in Hancock County
Type A gravel is the Maine base course for driveways, parking pads, camp roads and shed bases.
Town street standards call the same material out by those letters, and pits and yards sell it that way.
Bank run gravel comes out of the pit as it lies, unprocessed, so it is a filler course rather than a finished driving surface. Driveway gravel is the 3/4 inch crushed gravel Maine yards sell for the top of a drive.
Stone dust, also called screenings, beds pavers and walkway stone.
For drainage, 3/4 inch crushed stone and drain rock are washed clean stone. Riprap handles bank and culvert work where wave and runoff scour bite into shoreline and ditches.
Ground conditions across Hancock County
Across the Downeast coast and blueberry barrens, coarse sandy and bouldery till sits over granite and volcanic bedrock with ledge close to the surface. Broad glacial outwash sand and gravel underlies the barrens, with marine clay in the lower valleys and extensive peat and bog ground.
That split drives two different drainage problems. Shallow soil over ledge and wide areas of bog leave water sitting on the surface, so a base needs clean stone under it to move water away.
The outwash barrens drain almost too fast and wash out unbound surfaces, so the same drive needs a bound, compacted course on top.
The working season is short, with a late spring thaw near the water and fog and damp that slow curing and compaction. Plan base and paver work for the middle of the season.
Winters here are long and cold with heavy frost, held slightly in check near the water by fog and sea air, and hard frost heaving on gravel roads and camp drives every spring. Frost depth is commonly about 4 to 5 feet, deeper on the inland barrens than at the shore.
The local building official sets footing depth.
Some of the largest tides on the coast bring surge and wave action onto exposed granite shoreline, plus runoff scour on the sandy barrens and at culvert outlets. Riprap is the answer at the water and at ditch ends.
Choosing the right material
Penobscot County sits in The Maine Highlands, over rolling uplands of dense stony till on slate, schist and granite, cut by long esker sand and gravel systems, with marine clay in the lower Penobscot valley and wide areas of bog and wet till between the hills.
That ground is finer and wetter than the coarse till and outwash sand found across the Downeast coast and blueberry barrens.
The difference shows up in drainage. Where wet till and marine clay hold water, a clean open stone layer does more of the work than it does on the free-draining barrens, where a compacted crushed gravel course carries the surface.
Washington County shares the ground region with this county. The soil, the shallow ledge, the outwash and the bog ground are the same, so the same materials suit both.
