Including the necessary layer of base rock and related installation costs, pea gravel usually costs about $5 per square foot on average, as of 2015. The cost of pea gravel depends on a number of factors, including labor costs, the cost of related equipment, delivery fees and equipment allowance.
Pea gravel has a smooth texture and is often found near bodies of water. Its smooth texture, inexpensive cost and 1/8- to 3/8-inch size make it very appealing for walkways, garden paths, driveways and playgrounds. Because of pea gravel's tendency to travel and shift, homeowners typically bookend pea gravel surfaces with an edging material such as brick, stones, black metal or a bender board.
