When is the best time of year to order base material in York County?

Base, driveway and paver work runs from the end of mud season into late fall, which is the longest working season in the state. Ground that sits wet through mud season firms up as it dries. Winter storms bring the highest flood risk to low coastal lots, so coastal work is easier once that passes.

What is the difference between topsoil and fill dirt?

Fill dirt is bulk fill, backfill and grade raising, and it goes under a gravel course or a slab. Screened loam, which is the Maine trade name for topsoil, is the finish grade for lawns and seeding. Garden soil is a separate blend for raised beds and planting beds where plain loam alone is too lean.

What is Type A gravel and what is it used for in York County?

Type A gravel is the Maine base course. It goes under driveways, parking pads, camp roads and shed bases. In Maine, base aggregate is specified by those type letters, and pits and yards sell it under the same letters.

Type A gravel is the Maine base course, and it is where most drives and pads begin.

Under that base, the ground here is marine silt and clay of the Presumpscot Formation through the lowlands. Clay takes water slowly, so an under-built base shows it fast.

Materials delivered in York County

Order by the job you are building. A driveway, a patio and a drain each want a different material, and in Maine the yards name them by letter or by inch size.

Type A gravel is the base course here.

Type A and Type B are base gradations, and Type D is the common gravel subbase gradation.

Town street standards call the same materials out by those letters, and pits and yards sell them under them.

Bank run gravel comes out of the pit as it lies, unprocessed, so it fills and raises grade rather than finishing a drive. Top it with a crushed gravel course when you want a driving surface.

For drainage, 3/4 inch crushed stone runs trenches and drywells. Riprap armours shore and stream banks and culvert outlets, and it sells in ranges such as 6 inch and 12 to 24 inch.

On the finish side, stone dust beds pavers and flagstone, pea stone covers walkways and dog runs, and screened loam or garden soil takes the lawn and beds. Bark mulch dresses borders, and river rock, also called round stone, suits dry stream beds and drip edges.

Ground conditions across York County

Across the Southern coast and Presumpscot clay lowland, marine silt and clay sits through the lowlands, with sand and gravel outwash on the higher terraces. Stony till and granite ledge show on the hills, and salt marsh and beach sand run along the shore.

That clay takes water very slowly. Yards and drives sit wet through mud season, and low ground near tidal water backs up in coastal storms and high tides.

Where ground stays soft, a drainage layer of washed stone before the base course keeps the base from pumping. On the coast, storm surge and wave action work on the beaches and tidal shore.

Rivers and tidal creeks scour their banks after heavy rain, and marine clay banks slump where they are cut or undermined. Riprap and large river rock are the usual answers at the water line.

This is the longest working season in the state. Base, driveway and paver work runs from the end of mud season into late fall, and winter storms bring the highest flood risk to low coastal lots.

The ocean keeps winter lows milder than inland Maine, but the ground still freezes hard and thaws repeatedly. Gravel drives and walks heave every spring as the frost comes out.

Choosing the right material

Start with the ground. Type A gravel is the Maine base course, but clay ground that holds water wants a washed drainage layer under it.

For a driveway, bank run gravel fills and raises grade, Type A gravel builds the base, and driveway gravel finishes the surface. A patio wants stone dust for the setting bed, with pea stone or walkway gravel on the paths around it.

For a drain, 3/4 inch crushed stone and drain rock move water, and 3/8 inch stone fits narrow trenches where the coarser size is too big. #57 and #67 stone give a clean base under slabs, and #8 and #89 crushed stone fill paver joints.

Soil and fill split the same way. Fill dirt is bulk fill and backfill, screened loam is the lawn and finish grade, and garden soil is for raised beds and planting beds.

Mason sand and washed sand handle mortar, concrete and bedding.
