Gravel, Stone and Soil for Penobscot County, ME
Maine Rock Supply handles gravel, stone and aggregate delivery in Penobscot County, ME. Snowmelt and rain run hard off these hills, and they scour ditches, culverts and camp road edges on the way down.
Type A gravel is the Maine base material that answers that. Order it online by the ton or the yard and a dump truck tips it where you need it.
Ground Conditions Across Penobscot County
Across the Central hills and Penobscot Valley, the uplands are dense stony till over slate, schist and granite. Long esker sand and gravel systems cut through that ground, and the lower Penobscot valley carries marine clay.
Dense till with a hardpan layer sheds water sideways instead of down. Ground stays saturated through snowmelt, while the esker gravels beside it drain freely.
That split decides what a base has to do. On wet till, an under-built course pumps and ruts.
On esker ground, water moves and a compacted course holds.
A shorter season than the south shapes the work here. Frost has to be fully out before base can be compacted, and the window closes earlier in the hill towns.
Cold interior winters bring deep frost, a long freeze and a heavy thaw. Frost depth runs about 5 feet in the Bangor area, where the city publishes that figure, and comparable or deeper in the surrounding hill towns.
Footing depth is set by the building official.
Snowmelt and rain also cut banks along the Penobscot and its tributaries. Exposed till on logging and camp roads gullies fast, so slope protection belongs in the plan from the start.

Name the job, then pick the material. A gravel drive, a patio, a drain and a camp road each want a different product.
Choosing the Right Material
Aroostook County sits on the Aroostook plateau and Saint John uplands, where deep, well drained silt loam covers limestone, slate and calcareous shale. That ground grades to stony till and thin soil over harder rock in the hills.
Well drained silt loam changes the base choice. Water moves through it instead of sitting, so a compacted Type A gravel course can go on prepared ground without the saturated-till problem.
Hancock County covers the Downeast coast and blueberry barrens, on coarse sandy and bouldery till over granite and volcanic bedrock with ledge close to the surface. Broad glacial outwash sand and gravel sits under the barrens.
Ledge close to the surface changes the drainage choice. Where rock stops the digging, a clean washed stone and a drain line matter more than extra fill.
Somerset County sits in the same Central hills and Penobscot Valley ground as Penobscot County. Rolling uplands of dense stony till over slate, schist and granite, with marine clay in the lower Penobscot valley and bog and wet till between the hills.
The ground is the same, so the material approach is the same: bank run gravel to raise grade, Type A gravel as the base, driveway gravel on top.

Questions About Penobscot County Materials
When is the best time of year to order base material in Penobscot County?
Wait until frost is fully out of the ground. Base material has to be compacted, and frozen or thawing ground will not take it.
In the hill towns the workable window opens later and closes earlier than in the Bangor area. Order once the ground has drained and firmed up.
What is the difference between topsoil and fill dirt?
Screened loam is the Maine trade name for topsoil. It is the planted layer for lawn repair, seeding and finish grading.
Fill dirt is bulk fill for backfill and raising grade under a gravel course. Fill dirt is not a growing medium, and loam is not structural fill.
What is Type A gravel and what is it used for in Penobscot County?
Type A gravel is a crushed gravel base course.
Maine town street standards call the same material out by those letters. It goes under driveways, parking pads, camp roads and shed bases.
