Bulk Aggregates for Patios in Liberty, ME

Maine Rock Supply sells gravel and aggregate delivery in Liberty, ME to two kinds of buyers: contractors who know the spec names and homeowners who just want the patio to sit flat. Type A gravel is the base that carries both, and the bedding layers under pavers and flatwork are where the details show.

Around here the ground under a patio is often thin stony till over ledge, so what happens between the subgrade and the pavers matters more than on deep soil.

Ground and Conditions in Liberty

On the Midcoast peninsulas and Penobscot Bay, thin stony till sits over granite and metamorphic ledge on the ridges. Water has nowhere to go when the ledge is close to the surface, so it stays where it lands.

Pockets of outwash sand and gravel sit between those ridges, and marine clay and silt fill the low ground in the valleys.

A thin base shows its failure quickly on that ground: the surface pumps, dips at the joints, and pavers rock as the freeze and thaw cycles work through the winter and the spring frost heaves move in.

The fix is a base that spreads load instead of punching into soft clay, and a bedding layer fine enough to keep the surface true.

Work runs from the end of mud season into late fall. Ground that holds water at the surface through snowmelt and mud season is the reason timing matters as much as material choice.

Frost depth is commonly about 4 feet along the shore and deeper on the inland ridges, but the local building official sets footing depth, so check with them before pouring or setting anything structural.

Materials for Liberty Projects

Bedding under pavers and flatwork is where a patio either stays flat or starts to move. Stone dust, also called screenings or crusher dust, is the New England default setting bed under walkway stone and patio pavers.

It locks up tight under a plate and gives a flat surface to lay on.

Under the bedding, Type A gravel is the Maine base course.

It goes under driveways, parking pads, camp roads and shed bases as the compacted structural layer.

Where the ground is soft or wet, 1 1/2 inch crushed stone, also called #4 crushed stone, stabilizes the subgrade before a gravel course goes on. It is a heavy drainage stone for wet subgrade and soft spots.

For drainage trenches and drywells around a patio, 3/4 inch crushed stone, also called 3/4 stone or 3/4 inch washed stone, sheds water rather than holding it. It is what keeps the water moving away from the base.

For the joints between pavers, #8 crushed stone and #89 crushed stone fill the gaps. Both are fine clean stone, and both are spec designations rather than yard names.

Pea stone, also called 3/8 inch pea stone or Natural Pea Gravel, lines walkways and dog runs and beds pipe.
