Crushed marble chips cost $130 per cubic yard, $93 per ton, or $4.81 per cubic foot. White marble gravel is expensive, but it increases property value and is very attractive when used for gravel driveways or landscaping. Marble stays cool during the summer, although it does produce a glare. Crushed Shells Crushed shells cost $2 per square foot, $40 per cubic yard, or $50 per ton on average. Prices depend on the type of shells and location. Crushed clamshells are the cheapest in Florida, Georgia, and Alabama, where it's $10 per ton, $14 per yard, or $0.53 per cubic foot for 1" size washed White Seashells. Crushed oyster shells are off-white and gray, clamshells have lighter shades of yellow-white and pale-cream, and scallop shells have light-brown tones. Over time, all shells will become bleached-white. Paving with seashells is better for the surrounding soil, deters weeds and pests, and it's eco-friendly. Shells make excellent pathways but aren't pleasant to exposed feet. Shale Gravel Cost Shale gravel costs $28 to $85 per cubic yard, $20 to $60 per ton, or $1 to $3 per cubic foot depending on the size of the rocks. Cheaper shale is the natural, untreated rock. The more-expensive shale gravel is expanded shale, kiln-heated to make it porous for better drainage. Expanded shale is best for clay-based soils, especially in areas prone to flash flooding. Crushed shale comes in neutral grey colors and occasionally reddish-brown or charcoal shades. Its mostly fossilized clay, which is strong but not quite as durable as granite or limestone. Blue Stone Gravel Crushed bluestone gravel rock costs $52 per ton or $74 per yard when picked up from a local quarry. Prices can double when you include delivery charges. Larger sizes of decorative-quality bluestone gravel cost up to $155 per cubic yard or $109 per ton when you purchase at least 5/8 of a cubic yard from a quarry. Often referred to as "Piedra Azul Triturada," this type of limestone or sandstone comes in attractive shades of dark-blue to blue-gray. Blue stone also looks beautiful for the bottom layer of garden ponds, and its composition provides benefits for your soil. Return to Top Gravel Installation Cost Estimator Below are average cost estimates for gravel installation. Paving contractors typically quote a total price based on the project, instead of per yard or hour prices. How Much Does Spreading Gravel Cost? Spreading gravel costs $10 to $25 per cubic yard or $46 per hour depending on the job size, rock type, and crew efficiency. Large jobs with a 3-person crew and a tractor spread 12 cubic yards per hour. Smaller landscape projects spread 2 to 4 yards by hand for $22 per cubic yard. Find landscapers near you to help. View pros Cost To Install Landscaping Gravel Installing colored gravel or landscaping rock costs $50 to $90 per ton or $1 to $4 per square foot. A complete landscaping installation costs $3,000 to $16,000 depending on your yard size and choice of materials. Use gravel mulch for xeriscaping to create long-lasting pathways around your plants and trees. In damp climates, gravel also prevents fungi growth in your soil since it doesnt trap in moisture like bark mulch. Installing gravel as mulch in your garden is an easy DIY project. Dig out about 2" of soil, lay down a piece of geotextile fabric, then spread the gravel on top of the fabric. Be sure to keep a couple of inches of space between your gravel mulch and the roots of your larger plants. Avoid using gravel as mulch around plants that thrive in highly acidic soil. The high mineral content of the rocks will make your soil more alkaline over time. Gravel Driveway Installing a gravel driveway costs $1 to $3 per square foot depending on the type of gravel and installation quality. A 12'x25' single-car gravel driveway costs $300 to $900 to install 4" to 8" deep, and a double-car runs $600 to $1,800. Adding a 12' wide road a quarter-mile long costs $15,000 to $60,000. When extending your existing driveway, material costs for sand, gravel, paver stones, and edging are $750 to $800 for building an addition of 5' x 20'. Start with a layer of sand about 4" thick, with 2" of pea gravel on top. Next, lay out large paving stones and fill in the gaps between the stones with the remaining pea gravel and tamp it down to make it level. Residential Gravel Road Installing a 12' residential gravel road costs $5 to $10 per linear foot depending on the size and depth, local weather conditions, and permit costs. For large rural properties, a gravel road costs $21,000 to $65,000 per mile to install. Gravel Walkways & Paths Gravel walkways or paths 4" deep cost $10 per linear feet with pea gravel, a crusher-run gravel base layer, landscape fabric beneath to block weeds, and edging. These estimates assume an average path width of 3 to 4 feet. DIY materials to create your own gravel path cost $100 to $1,000 and can be installed in an afternoon. First, install a durable landscape edging. Either coarse sand, finely crushed limestone, granite, or crusher run all work well as a 2-inch base foundation. Water the finer crushed stones of your base layer and use a tamper tool to compact it down flat. Then, spread out the top layer of rocks at 2" thick to complete the path. Set large paving stones in the gravel to create an eye-catching pattern and further stabilize river rock. Smaller stones work best since they compact together to form a level surface more easily. You may not want a gravel walkway if: You'll have to shovel it often in snowy weather. You'll likely end up shoveling away some of the stones as well as the snow. Anyone in your household will be using a cane or walker. A walking aid can sink slightly in the gravel and may cause a fall. You prefer to walk barefoot outside. Gravel Patio Building a 10'x20' gravel patio with costs $200 to $500 for the wooden patio border wall with rebar, geotextile fabric below, and the gravel. Installing a gravel patio is an easy DIY project and cheaper than poured-concrete or brick patios. A backyard patio thats only for people needs a gravel layer 4" thick. Crushed limestone rocks remain stable, so they dont need an additional base layer of crushed stone to keep them level. Smooth rocks like river rock shift slightly under your feet, so youd need to spread out a 2" layer of base rock first. Then spread out a 2" layer of your river rock on top. Gravel Play Areas You can build a pea gravel play area for kids for $100 to $200. A gravel activity box is an excellent alternative to a sandbox that's less messy and inexpensive since it only needs around one cubic yard of loose pea gravel. For toddlers and young children, 4" of gravel is sufficient for digging and playing. If you want to use smooth pea gravel to cover areas around slides or swing sets, then it will cost more because a 9" thick layer of gravel is needed to cushion any hard falls. Add a wooden frame or retaining wall around all gravel areas to keep the gravel from spreading all over your backyard. Gravel Garage Floor Gravel for a 20'x20' garage floor costs $200 to $800, or $0.50 to $2.00 per square foot. Total costs to install range from $400 to $2,000 depending on labor and the type of drainage system installed. A standard concrete slab costs $3,000 to $6,000 depending on the type of sub-soil and the gravel base used. Gravel For Crawl Space A common mistake is trying to use gravel as a replacement for a moisture barrier on a crawl space floor. The gravel helps the water move into your crawl space faster, rather than keeping moisture out. Gravel can cause water damage to your footers and foundation. Instead, keep gravel in your drainage trenches only. To fill in crawl space trenches for a drainage system along the inner perimeter of a 3000 SF foundation with drain rock, youll need about 20 cubic feet of gravel that costs $20. Another option is installing a vapor barrier of 6 mil plastic for $600 to decrease moisture if your crawl space isnt prone to flooding or collecting water. Then covering the entire crawl space with gravel costs $0.50 to $2.00 per square foot. Crushed Stone & Gravel Sizes Crushed stone and gravel comes in a variety of sizes ranging from dust screenings, all the way up to 10 inches in diameter. Most gravel is sold by the bag, cubic yard, or ton. Crushed Stone Size Chart Sizes Dust Screenings " " " " 1" 2" 3.5" 4" 10" Return to Top Frequently Asked Questions Where To Buy Gravel? Gravel is available to buy from home improvement stores such as Home Depot, rock quarries, landscaping centers, crushed stone suppliers, online, or a local landscaper. Rock quarries sell the cheapest gravel order at least 10 yards for free delivery, and at least 20 tons for the cheapest rates. When buying gravel in bulk, ask about delivery and spreading costs. The gravel may be dumped in one pile or roughly spread along a planned driveway, depending on the terms negotiated. Find landscaping professionals near you. View pros How Much Gravel Do I Need? A 4' x 20' walkway or flower bed needs 3 cubic yards of gravel, a 10' x 20' patio requires 7.4 yards, a 12' x 25' 1-car driveway needs 11.1 cubic yards, a 24' x 24' 2-car driveway needs 21.3 yards, and 29.6 yards for a 12' x 100' gravel road.

The overall depth required depends on the soil's condition. Calculate the total volume of gravel youll need based on the size of your project. Multiply the length (in feet), times the width, times the depth, to calculate cubic feet. Then, divide that number by 27 to calculate cubic yards. There are approximately 1.4 tons of stone per cubic yard. Length Width Depth = Cubic Feet Cubic Feet 27 = Cubic Yards Cubic Yards 1.4 = Tons How Much Does A Ton Of Gravel Cover? When laying the recommended gravel-layer depth of 4", then a ton of pea gravel covers an area of 40 to 50 square feet. Spreading out 1-ton of gravel at 2" deep covers 80 to 100 square feet, while 6" deep covers 25 to 35 square feet or less if you use larger stones. The amount of area you can cover with gravel depends on the depth of your project and the gravel size. 1-Ton of Gravel Coverage Depth Square Feet Covered 2" 80 100 4" 40 50 6" 25 35 12" 12 18 How Much Does A Bag Of Gravel Cost? A plain bag of pea gravel or crushed stone costs $2 to $6 per bag and covers 2 cubic feet or less depending on the type. Decorative or colored gravel costs $6 to $8 per bag. Bags of gravel are sold at most home improvement stores such as Home Depot or Lowe's. Bag of Gravel Cost Type Cost Per Bag Plain Pea Gravel $2 $6 Decorative or Colored Gravel $6 $8 How Many Tons of Gravel In A Dump Truck? A 10-wheel dump truck carries 12 to 20 tons of gravel or around 8 to 10 yards depending on the rock size and type. Return to Top DIY vs. Hiring a Pro Smaller landscape and walkway gravel projects can be done DIY for just the cost of the materials and a day of work. Consider hiring a professional for large or complex jobs such as a gravel driveway, which requires multiple layers of gravel and a drainage system. Another option is to purchase the materials yourself, then hire a landscaper for $45 per hour to install.

Water the finer crushed stones of your base layer and use a tamper tool to compact it down flat. Then, spread out the top layer of rocks at 2" thick to complete the path. Set large paving stones in the gravel to create an eye-catching pattern and further stabilize river rock. Smaller stones work best since they compact together to form a level surface more easily.

Gravel Play Areas You can build a pea gravel play area for kids for $100 to $200. A gravel activity box is an excellent alternative to a sandbox that's less messy and inexpensive since it only needs around one cubic yard of loose pea gravel. For toddlers and young children, 4" of gravel is sufficient for digging and playing.

Total costs to install range from $400 to $2,000 depending on labor and the type of drainage system installed. A standard concrete slab costs $3,000 to $6,000 depending on the type of sub-soil and the gravel base used. Gravel For Crawl Space A common mistake is trying to use gravel as a replacement for a moisture barrier on a crawl space floor. The gravel helps the water move into your crawl space faster, rather than keeping moisture out. Gravel can cause water damage to your footers and foundation. Instead, keep gravel in your drainage trenches only. To fill in crawl space trenches for a drainage system along the inner perimeter of a 3000 SF foundation with drain rock, youll need about 20 cubic feet of gravel that costs $20. Another option is installing a vapor barrier of 6 mil plastic for $600 to decrease moisture if your crawl space isnt prone to flooding or collecting water. Then covering the entire crawl space with gravel costs $0.50 to $2.00 per square foot.
