Rip rap typically costs $35-$100 per ton for stone alone, or about $80-$250 per ton installed, with a common project average near $125 per ton. Rock size, delivery distance, shoreline or slope conditions, and equipment access have the biggest effect on the quote.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Rock only | $35 per ton | $65 per ton | $100 per ton | Quarry price; size and stone type vary |
| Delivered rock | $50 per ton | $90 per ton | $150 per ton | Short-haul delivery at the low end |
| Installed rip rap | $80 per ton | $125 per ton | $250 per ton | Includes typical placement labor and equipment |
| Coverage | About 1.5 tons | About 2 tons | About 2.5 tons | Per 10 linear feet for a 2-foot-wide, 1-foot-thick layer |
What Rip Rap Costs Per Ton for Common Rock Sizes
For ordinary erosion-control work, angular quarry stone commonly costs $35-$100 per ton before delivery. Smaller 2-6-inch rock often falls around $35-$65 per ton, while larger 6-12-inch stone may cost $50-$90 per ton. Specialty stone, limited local supply, or very large armor rock can reach $100-$150 per ton.
An installed estimate usually runs $80-$250 per ton when it includes delivery, site preparation, and machine placement. Small jobs may have a higher per-ton price because trucking and equipment mobilization are spread across fewer tons. Assumptions: standard quarry stone, typical U.S. labor rates, and a site reachable by dump truck and excavator. For a standard, accessible project, budgeting about $90-$160 per installed ton is a practical starting point.
How Quarry, Trucking, and Placement Shape the Invoice
Quotes may separate stone, freight, labor, and equipment, or bundle them into one installed rate. Compare what each estimate includes: a low quarry price does not cover hauling, fabric, grading, or placement. Minimum truck charges can also make a small delivery expensive.
| Quote item | Typical range | Pricing basis | What changes it |
|---|---|---|---|
| Quarry stone | $35-$100 | Per ton | Rock size, type, quarry supply |
| Delivery | $10-$50 | Per ton, or minimum load fee | Haul distance and truck access |
| Placement labor | $20-$75 | Per ton | Bank shape, hand work, crew time |
| Equipment and grading | $250-$1,200 | Per project | Excavator size and site preparation |
| Filter fabric | $0.50-$2.50 | Per square foot | Fabric grade and area covered |
Labor may be charged by the hour instead of by ton. A small crew and excavator can cost roughly $100-$250 per hour, depending on region and machine size. Ask whether mobilization, fabric installation, and final grading are included in the labor line.
The installed rate is easiest to compare when the quote lists both tonnage and the included work.
Why Rock Size and Bank Slope Change the Installed Rate
Rock size is selected for the water flow, soil, and slope—not just appearance. A 2-6-inch stone layer may suit light drainage or low-energy runoff, while a streambank exposed to stronger flow may require 6-12-inch or larger armor stone. Larger rock can cost more per ton and may need a heavier excavator or truck.
Thickness and slope determine the tonnage. A 1-foot layer over 100 square feet takes roughly 5-7 tons, depending on stone density and placement. Increasing thickness to 18 inches can raise stone needs by about 50%. Steeper banks, soft ground, roots, and water access constraints can add labor or require a more gradual slope and extra preparation.
Confirm the specified rock diameter and layer thickness before comparing prices; a cheaper quote may simply use less stone.
How Much Rip Rap Covers Per Ton Along a Shoreline
One ton of rip rap generally covers about 15-25 square feet at a 6-12-inch thickness. Coverage varies with rock density, shape, and how tightly it is placed. As a planning example, a 2-foot-wide shoreline strip with a 1-foot-thick layer uses roughly 1.5-2.5 tons per 10 linear feet.
A 100-foot shoreline with those dimensions may therefore need about 15-25 tons. At $80-$250 per installed ton, the basic installed range would be $1,200-$6,250, before unusual access work or extensive grading. Have the contractor measure the bank face rather than relying only on shoreline length.
Order quantities should include a modest allowance for uneven ground, but excess rock can be costly to haul away.
When Delivery Distance and Access Add Charges
Quarry distance affects freight: a nearby source may add $10-$25 per ton, while a longer haul can add $25-$50 or more. Remote sites may face a minimum charge for a truck even when only a few tons are needed. Urban delivery can cost more when trucks face restricted hours, parking limits, or smaller-load requirements.
Equipment access is another major price variable. A dump truck that can unload beside the bank keeps handling simple. If stone must be moved with a compact loader, carried by hand, or placed from a temporary track, labor and equipment can add several hundred dollars to a small job. Wet or unstable ground may also require mats or additional site work.
Ask the supplier to identify the quarry, estimated haul distance, truck size, and any small-load fee.
Three Rip Rap Quotes for Different Shoreline Jobs
These examples use illustrative installed rates; local quotes can differ with quarry supply, labor, and access. They show how quantity and site conditions affect the total more than a per-ton price alone.
- Small drainage swale: 8 tons of 2-6-inch stone at $105 per ton installed, plus $250 for fabric and grading, totals about $1,090. The site has truck access and light preparation.
- Accessible pond edge: 22 tons of 6-12-inch stone at $135 per ton, including delivery and excavator placement, totals about $2,970. The estimate assumes a 100-foot reach and ordinary bank shaping.
- Steep streambank: 40 tons of larger armor stone at $190 per ton, plus $1,200 for difficult access and site preparation, totals about $8,800. The higher price reflects equipment time and more demanding placement.
Check each quote’s measured area, specified stone size, thickness, and included preparation before choosing by total alone.
Ways to Lower a Rip Rap Budget Without Undersizing
Request prices from more than one nearby quarry or contractor, and compare the same stone size, thickness, and delivery quantity. Scheduling a full truckload can reduce the per-ton freight charge when the project genuinely needs that volume. Combining delivery with nearby work may also avoid a separate mobilization fee.
Limit unnecessary excavation, remove loose debris before the crew arrives if safe, and verify whether existing stone can be reused. Choose locally available rock rather than a specialty color or distant source. Avoid reducing thickness or substituting smaller rock unless the drainage or erosion design supports that change; under-sized stone can wash out and require replacement.
The safest savings usually come from reducing hauling and avoidable site work, not from cutting the specified rock size or layer depth.
