Aggregate & Gravel Supply in Washington County, Maine

Driveways, Roads, and Heavy Use Projects

Washington County roads and driveways face coastal salt, seasonal frost heave, and areas with poor natural drainage. We supply aggregates and mixes built to resist washout and movement while providing a long-lasting surface.

Driveway Solutions

For most residential driveways in Washington County, start with a compactable base and finish with a wearing course that resists erosion. Our common approach uses crusher run or road base at the subgrade and a surface layer of driveway gravel or 3/4 inch crushed stone where higher load capacity is needed.

• Typical driveway build: compacted fill dirt then road base then driveway gravel or 3/4 inch crushed stone.
• Benefits: improved load distribution, reduced rutting, and better winter durability.
• Projects: rural driveways, cottage access roads, and farm lanes.

Road Base and Crusher Run

Road base and crusher run are common in projects that require structural integrity. Road base provides a graded, engineered layer for private roads. Crusher run compacts tightly for heavy use aprons and garage approaches.

Drainage & Erosion Control

Many coastal lots and low-lying parcels in Washington County experience seasonal runoff and erosion. Proper aggregates can reduce surface flow, protect shorelines, and direct water away from foundations.

French Drains and Subsurface Systems

Drain rock and #57 stone are both excellent for French drains and footing drain systems. Drain rock provides high permeability and resists clogging, which is ideal where sandy loam meets rock outcrops.

• Drain Rock: used for trench drains and perimeter foundation systems.
• #57 Stone: great for bedding pipes and areas with higher flow rates.
• Recommendation: pair drainage aggregates with filter fabric for longevity.

Shoreline and Bank Stabilization

For erosion near tidal zones and streams, river rock and larger angular stone can dissipate wave energy and protect banks. We deliver rock sizes suited for cobble shorelines and smaller beds for decorative stabilization.

Decorative Rock, Hardscape, and Garden Projects

Washington County property owners often seek materials that match the natural coastal palette. Rounded river rock, pea gravel, and decomposed granite offer neutral tones and low maintenance.

Walkways and Patios

Use walkway gravel or pea gravel for paths where drainage and comfort underfoot are priorities. Decomposed granite compacts well for rustic patios and requires less edge restraint in natural settings.

• Walkway Gravel: comfortable underfoot and easy to level.
• Pea Gravel: decorative and smooth, best contained with edging.
• Decomposed Granite: natural look, good for ADA-accessible paths with proper compaction.

Landscaped Beds and Accents

River rock and decomposed granite work well for planting beds, dry stream features, and around native shrub plantings. Pea gravel complements coastal plantings and children’s play areas.

Soils and Sand Products

Topsoil, fill dirt, and various sands support planting, turf establishment, and construction tasks across the county's mixed soils. Whether you need screened topsoil for a new lawn or washed sand for masonry, we have county-ready materials.

Topsoil and Fill

Topsoil is screened for planting beds and is useful for final grading. Fill dirt is suitable for structural fills and leveling prior to paving or building.

• Topsoil: for gardens, lawns, and planting restoration after construction.
• Fill Dirt: for raising grades and backfilling excavations.

Sands: Mason, Washed, and Playground

Mason sand creates strong mortar mixes; washed sand and playground sand meet safety standards for recreation areas. Washed sand prevents organic matter from affecting mixes and keeps pavers stable.

Project Types and Use Cases

Our aggregates support a range of local projects from small residential improvements to larger municipal and commercial work. We tailor material selection to Washington County's coastal climate and soils.

Typical Projects

• Residential driveways and parking pads
• Septic system drain fields and French drains
• Shoreline stabilization and culvert projects
• Garden beds, pathways, and hardscape bases
• Road reconstruction and private access roads

Why Choose the Right Aggregate

Matching aggregate size and composition to the project's demands prevents common local problems like rutting, frost heave, and poor drainage. Aggregates that lock and interlock resist shifting on slopes and coastal exposures.

Gravel Monkey emphasizes dependable local service, reliable schedules, and materials matched to Washington County conditions. We operate with the practical needs of homeowners, contractors, and municipal crews in mind.

• Free delivery across Washington County on most orders
• Multiple material options to match soil and drainage needs
• Bulk delivery by cubic yard—ideal for driveways and larger jobs
• Clean trucks and professional placement to minimize site disruption

Delivery Considerations for Washington County

Many properties have narrow lanes, seasonal limitations, and soft shoulder conditions. We coordinate deliveries around tides, town ordinances near coastal roads, and client access constraints. Our drivers are experienced with rural Maine properties and work to place materials with minimal impact.

Choosing Aggregates for Local Soil and Climate

Washington County's geology includes glacial till, bedrock outcrops, and coastal alluvium. Soils can be acidic and rocky with variable drainage. These conditions require aggregates that assist with runoff management and resist freeze-thaw damage.

Local Soil Notes

• Glacial till and rocky subsoils are common; expect variable bearing capacity.
• Coastal zones include sandy deposits and organic sediments near tidal flats.
• Acidic soils favor plant species adapted to Down East Maine—topsoil helps establish new plantings.

Climate and Seasonal Guidance

Winters bring freeze-thaw cycles and coastal storms. Aggregates that drain well and compact firmly reduce frost heave. For splash zones near the shore, choose larger rock or river rock to reduce material loss during storms.

Sustainability & Recycled Materials

Recycled crushed concrete offers a sustainable option for bases and parking areas. Using reclaimed aggregate reduces quarry demand and is a practical choice for many Washington County projects.

• Crushed concrete: recycled, cost-effective base material
• Reduced transport and quarry impacts by choosing local aggregate blends
• Best for projects where recycled base performance is acceptable

Ordering, Quantities, and Placement Tips

Estimating quantities is easier when you know the project footprint and desired depth. We supply by the cubic yard for bulk aggregates and provide guidance on coverage and compaction.

Estimating Common Quantities

• 1 cubic yard covers roughly 108 square feet at 1 inch depth
• Driveway base often requires 4 to 8 inches of compacted aggregate depending on use
• Walkways typically need 2 to 3 inches of compacted base plus 1 to 2 inches of wearing surface

Placement Tips

Place aggregates on a prepared subgrade, use geotextile fabric where required, and compact in thin lifts. For drainage systems, maintain clearances and use clean drain rock around pipes to prevent clogging.
