Homeowners and contractors commonly pay for epoxy injection crack repair to stop water leaks and stabilize foundations or concrete slabs. Typical costs hinge on crack width, length, location, concrete age, and access. This guide presents cost ranges and pricing drivers for U.S. projects, with practical budgeting guidance.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Repair scope | $300 | $1,200 | $4,000 | Few small cracks vs. extensive cracking |
| Epoxy kit or resin | $25 | $75 | $250 | Per crack or per foot basis |
| Labor & crew | $350 | $1,000 | $3,000 | Includes surface prep and sealing |
| Time to install | 2–4 hours | 6–12 hours | 1–2 days | Depends on crack network |
| Permits & codes | $0 | $150 | $1,000 | If required by jurisdiction |
| Delivery/ disposal | $20 | $100 | $400 | Disposal of waste and packaging |
| Warranty & contingencies | $0 | $100 | $500 | Manufacturer or contractor warranty |
Assumptions: region, crack length, access, and cure time.
Overview Of Costs
Epoxy injection cost ranges generally run from a few hundred to several thousand dollars per project. For small cracks in a garage slab, budgets might stay in the low hundreds, while large or multi-crack networks in basements or foundations can approach the mid to high thousands. The price per linear foot typically spans $5-$25, with higher rates for deeper injections, multiple passes, or extended crack lengths.
Cost Breakdown
Table below shows how costs accumulate across common epoxy injection projects.
| Materials | Labor | Equipment | Permits | Delivery/Disposal | Warranty | Contingency | Taxes |
|---|---|---|---|---|---|---|---|
| $25-$250 per crack or $2-$6 per linear ft | $100-$800 per crack | $50-$400 | $0-$150 | $20-$100 | $0-$200 | $0-$200 | Varies by state |
Typical projects blend epoxy resin costs with labor for surface prep and sealant application.
What Drives Price
Key factors include crack dimensions, substrate condition, and access complexity. Wider or longer cracks require more resin and longer cure times. Deeper penetration or multiple passes to fully fill the crack increases both material and labor costs. Concrete type, moisture exposure, and required surface restoration add further variations, as do local wage levels and demand cycles.
Ways To Save
Consider pre-qualification and planning to reduce surprises. Consolidate multiple cracks into a single treatment plan if feasible and time windows align. Opting for standard resin grades instead of specialty formulations can trim material costs. Scheduling during off-peak seasons or obtaining multiple bids may yield measurable discounts, especially for larger jobs.
Regional Price Differences
Prices vary by market; three representative regions illustrate typical deltas. In the Northeast, higher material and labor costs raise price by roughly 10-20% vs. national averages. The Midwest often lands near the national average, with small regional swings. The South and Southwest can be 5-15% lower due to lower labor rates and material sourcing. Local demand, climate-related concrete conditions, and permit practices can shift economics by ±10% in either direction.
Labor, Hours & Rates
Labor is a major component of total cost. Journeyman rates may range from $50-$120 per hour depending on region and skill, with crews typically working 2–12 hours per site depending on crack network. The total labor figure often dominates when cracks require extensive routing, cleaning, and multiple resin injections.
Additional & Hidden Costs
Some projects incur extras beyond the base repair. Surface grinding or patching after injection, moisture barriers, or re-sealing adjacent concrete can add $100-$1,000. If structural repair is implied or crack movement recurs, more invasive measures or follow-ups may be necessary. Expect occasional overtime charges for tight schedules or remote locations.
Real-World Pricing Examples
Three scenario cards illustrate typical outcomes.
Basic Scenario
Crack length: 10 ft, 1/16″ width, accessible in a single area. Labor hours: 2–4. Per-unit: epoxy $5-$8/ft. Total estimate: $300-$700. Assumptions: standard concrete, no moisture mitigation.
Mid-Range Scenario
Crack network: several cracks totaling 40 ft, minor surface prep. Labor: 6–10 hours. Materials: epoxy $6-$12/ft; delivery $50. Total estimate: $1,000-$2,200. Assumptions: typical basement slab, mild moisture present.
Premium Scenario
Extensive crack map totaling 120 ft, multiple passes and moisture concerns, requires sealant topping. Labor: 12–20 hours. Materials: epoxy $8-$15/ft; permits and disposal: $150-$400. Total estimate: $3,000-$6,000. Assumptions: hard concrete with water intrusion and cure time constraints.
Pricing FAQ
Q: Do epoxy injections require special permits? A: In many jurisdictions, a permit is not required for minor crack repairs, but some local codes or moisture mitigation projects may necessitate documentation. Costs in the permit line are typically modest but can increase the total if included.
Q: How long does an epoxy injection take? A: Typical injections take from a few hours up to a full day, depending on crack length, access, and cure requirements.
Q: Is epoxy injection permanent? A: Epoxy injections stabilize cracks and reduce water intrusion, but ongoing movement or new cracks can occur. Ongoing maintenance or monitoring may be prudent in some foundations.
