Pea Gravel
Small, rounded stones that create attractive, walkable surfaces for pathways, patios, and play areas.
What is Pea Gravel?
Pea gravel consists of small, rounded stones ranging from about 1/8 inch to 3/8 inch in diameter - roughly the size of peas, hence the name. These smooth, naturally rounded stones create a surface that's both attractive and comfortable to walk on.
The rounded shape of pea gravel allows the stones to shift and move slightly underfoot, creating a cushioned walking surface that's easier on joints than concrete or asphalt. This same characteristic provides excellent drainage, as water easily percolates through the gaps between stones.
In Northumberland County, pea gravel is a popular choice for informal pathways, patio seating areas, and under play structures. The neutral gray, tan, or brown tones complement most landscape styles and provide a natural, relaxed aesthetic.

Garden Pathways
Creates informal, natural-looking paths through gardens. The crunch underfoot adds sensory appeal to garden walks.
Patio Seating Areas
Define outdoor seating areas with a pea gravel surface. Comfortable underfoot and provides good drainage around furniture.
Playground Surfacing
Safe, impact-absorbing surface under play structures. Meets safety standards for fall zones when installed at proper depth.
Dog Runs
Excellent surface for dog kennels and runs. Drains well, easy to clean, and gentle on paws.
Container Drainage
Add to the bottom of large containers to improve drainage and reduce soil volume needed for large planters.
NOT For Driveways
Pea gravel moves too easily under vehicle tires. Use crusher run or clear stone for driveway applications.
Installation Tips
1. Excavation and Base
Excavate 6-8 inches for pathways. Install a 4-6 inch base of crushed stone or crusher run and compact thoroughly. This provides stability and prevents sinking.
2. Edging is Essential
Pea gravel spreads easily without containment. Install steel, aluminum, brick, or stone edging before adding gravel. This keeps the material in place and defines the space.
3. Landscape Fabric
Place landscape fabric over the compacted base before adding pea gravel. This prevents weeds while allowing drainage. Overlap fabric edges by 6 inches.
4. Proper Depth
Install pea gravel 2-3 inches deep over the fabric. This depth provides a comfortable walking surface while preventing stones from scattering. Deeper installation makes walking difficult.
5. Maintenance
Rake pea gravel periodically to maintain an even surface. Add material annually to replace what migrates or compacts. Remove leaves promptly to prevent decomposition and weed growth.
⚠️ Migration Warning
Pea gravel travels easily. Without proper edging, expect stones to scatter into lawns and adjacent areas. Regular raking and strong edging are essential for maintenance.
