About Pea Gravel
What is Pea Gravel?
Pea gravel is small, rounded rock approximately the size of a pea (1/8″ to 3/8″ diameter) with a naturally smoothed and weathered surface.
Common Applications
Perfect for pathways, patios, play areas, drainage, and ornamental landscaping because it is smooth to the touch and in appearance completely natural.
Weight Considerations
Pea gravel typically weighs about 100 pounds per cubic foot (1,600 kg/m³), which is heavier than the average landscaping material.
Drainage Advantages
Ideal for drainage construction since the spherical stones allow water to flow freely and do not cause soil erosion.
