Prices for concrete trench drains vary by size, depth, materials, and site conditions. This article breaks down the cost, including typical total price, per-foot estimates, and the main drivers of price in the United States. The keyword appears here to match search intent for cost and price inquiries about concrete trench drains.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Trench Drain Unit (2 ft section) | $40 | $70 | $110 | Concrete stub, grate not included |
| Grate Cover (stainless or polymer) | $20 | $45 | $90 | Per linear foot varies by material |
| Labor for 6–8 ft install | $500 | $1,000 | $1,800 | Excavation, placement, compaction |
| Permits/Inspections | $0 | $150 | $600 | Depends on city |
| Delivery/Haul-Off | $50 | $150 | $400 | Material drop-off and waste |
Assumptions: Midwest labor rates, standard 4-inch thick concrete, normal access, suburban site.
What Buyers Usually Pay for Concrete Trench Drain Installations
Typical total price ranges reflect project scope, length, and cover type. For a 6–12 foot run with a standard 4-inch thick concrete trench and a basic grate, homeowners can expect roughly $1,200-$2,800 installed, depending on region and access. Larger, deeper, or custom-molded units can push costs to $3,500-$6,000 for longer runs or complex drainage patterns. Per-linear-foot pricing generally falls in the $35-$90 per foot band, with higher end tied to heavier materials or decorative finishes.
Assumptions: single-story residence, standard soil, accessible work site, no additional drainage components beyond the trench and grate.
Cost by project size
Small projects (2–6 feet) typically land in the $600-$1,600 range installed. Medium runs (6–20 feet) often run $1,200-$3,000. Large or complex setups (20+ feet, sharp turns, or multiple inlets) commonly cost $3,000-$6,000 or more.
Major Cost Components in a Concrete Trench Drain Quote
Materials and labor dominate the quote, with permits and delivery as smaller but necessary parts. Below is a compact view of the usual components.
| Components | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials (concrete, forms, trench sections) | $40 | $60 | $120 | Includes formwork and sealant |
| Labor | $400 | $800 | $1,500 | Crew on-site for excavation, alignment, pour |
| Grate/Covers | $20/ft | $40/ft | $90/ft | Metal or polymer options |
| Permits | $0 | $150 | $600 | Local permit and inspection fees |
| Delivery/Disposal | $50 | $150 | $400 | Material drop-off and waste remove |
Assumptions: standard urban setting, no special backfill, no trench sealant beyond basic curing.
Key Variables That Drive Concrete Trench Drain Pricing
Depth, length, and cover choice are the top price levers. The deeper the trench or the longer the run, the more concrete, formwork, and labor are required. Regional wage differences add a wide spread to the final quote. A 4-inch-deep, 6-foot run with a basic grate is noticeably cheaper than a 12-inch-deep, 25-foot installation with a heavy-duty grate and decorative finish.
Assumptions: standard soil, no rock excavation, normal access, typical urban installation.
Regional Differences in Concrete Trench Drain Costs
Coasts and metropolitan zones generally show higher pricing due to labor and permitting. In the Northeast and West Coast, expect averages around $1,800-$4,000 for 15–25 feet with mid-range grates. In the Midwest and Southern states, the same scope often falls in $1,200-$2,800. Per-foot pricing typically ranges from $35-$90, depending on cover material and local codes.
Assumptions: urban region within standard climate with typical soil profile and access.
Labor Time and Crew Size for Trench Drain Projects
Labor hours scale with length, depth, and site complexity. A 6–12 foot run may require 8–16 hours of tradespeople time for excavation, formwork, pour, cure, and grating. Larger projects with multiple inlets or tight spaces can push labor to 40 hours or more. When scheduling, early coordination reduces overtime and costly delays.
Assumptions: one concrete crew, standard weather window, no significant site obstacles.
Options to Cut Costs Without Compromising Function
Control scope and materials to save money without sacrificing drainage performance. Consider using standard gray concrete instead of decorative finishes, limiting the number of inlet/outlet hookups, and choosing a simpler grate design. If a full trench is unnecessary, a shorter run with end caps and a single slope drainage line may meet needs at a lower price point. Bundling with adjacent flatwork or site improvements can yield modest discounts.
Assumptions: basic drainage requirement, standard forms and curing, no emergency timelines.
Per-Unit Pricing Scenarios: Per Linear Foot and Per Trap Installations
Pricing is often shown per foot or per inlet for clarity. Per linear foot installed, expect roughly $35-$90 for the trench and concrete, plus $20-$60 per foot for grate material. If a trench includes multiple inlet traps or cleanouts, per-trap charges often run $150-$450 depending on accessibility and hardware. A typical 10-foot run with one inlet might total around $1,000-$2,000, including grate and labor, while a 20-foot run with two inlets could be $2,000-$4,000.
Assumptions: standard 4-inch thick concrete, typical gray finish, mid-range grate.
Material Choices and Their Impact on Price
Material grade and cover type materially shift the price spectrum. Concrete grade and form quality affect base cost by roughly 10%-25%. Stainless steel or heavy-duty aluminum grates add $15-$40 per linear foot versus basic polymer or ductile iron options. Decorative finishes or custom molds can push costs up by 20%-40% in select markets. For most projects, a plain gray concrete trench with a standard grate provides solid function at the lower end of the price range.
Assumptions: mid-range grate, standard concrete mix, no specialty curing methods.
