Concrete contractors run on Portland cement, steel rebar, and ready-mix — three independent commodity markets inside every pour. Your supplier invoices against all three simultaneously. The Overcharge Ledger makes sure what hits your tickets is what you actually agreed to pay.
IBISWorld reports $110.5 billion in U.S. concrete contractor industry revenue in 2026, with 93,960 businesses and a 4.3% CAGR over the past five years. Federal infrastructure programs — the Infrastructure Investment and Jobs Act, the Inflation Reduction Act, and the CHIPS Act — have pushed structural concrete demand into highways, bridges, data centers, semiconductor fabs, and logistics facilities for the entire current cycle.
Every cubic yard of concrete placed carries a cement cost, an aggregate cost, and a rebar cost. All three are independent commodity markets, all three have been active, and your ready-mix supplier and rebar distributor price against all three simultaneously. What you were quoted and what you were invoiced across those three inputs is exactly what the Ledger reads.
Poured concrete foundations, footings, and basement walls for residential and commercial structures. Cement, aggregate, and rebar orders priced at permit and placed over weeks. By the time the pour happens, ready-mix pricing may have moved from the original quote.
Slabs, driveways, sidewalks, parking lots, and warehouse floors. High yardage orders against square-foot quotes. Ready-mix is priced per yard at delivery — a per-yard increase invisible on any single ticket becomes significant across a large slab job.
Tilt-up panels, parking structures, bridge decks, and industrial foundations. Multi-month projects with large rebar and cement volumes. Price movement between bid and final pour on a six-month job creates real exposure that no single delivery ticket captures.
Highway work, bridge rehabilitation, retaining walls, and public works. Bid environments where material prices are locked at award but suppliers invoice at delivery. Rebar and cement are both active commodity markets — the gap between bid-day pricing and invoice-day pricing is the Ledger's territory.
Pool shells, tunnel linings, slope stabilization, and custom structural work. Specialty mix designs with cement content specifications. A mix substitution — lower cement content, different admixture — billed at the specified mix price is a specification overcharge and a cost-of-materials discrepancy simultaneously.
Portland cement is an energy-intensive manufactured product — its price tracks energy costs, kiln capacity, and import competition. Rebar is a steel product — it tracks scrap metal markets, mill capacity, and trade policy. Aggregate is a logistics product — its cost reflects fuel and haul distance more than raw material. All three move independently. All three appear on your supplier invoices. None of them move in sync with your original quotes.
The BLS PPI for Hydraulic Cement (PCU3273103273100) reached 342.867 in February 2026 — more than 3.4 times the 1989 baseline. The PPI for concrete reinforcing bars (WPU1074051) jumped 6.9% from October 2025 to February 2026 alone — from 318.720 to 340.668.
That rebar move over four months is the kind of number your distributor uses to justify invoice prices that outrun your original bid. The Ledger holds your quotes and your invoices simultaneously — and maps every line item against what you actually agreed to pay. We record it. We measure it. We verify it. We do not provide financial advice.
On a large infrastructure or commercial concrete job, the gap between bid-day commodity prices and invoice-day commodity prices can be substantial — and legitimate cost increases give suppliers cover to move prices beyond what the market actually moved. The Ledger documents which increases track the commodity indexes and which exceed them. That distinction is the proof package.
Cement, rebar, and aggregate each move on their own schedule. That gives suppliers three independent justifications to raise prices — and three independent places to hide margin expansion inside legitimate cost movement.
Ready-mix quoted per yard at project start. Pours happen across weeks or months. Each delivery ticket carries a slightly higher per-yard price — no change order, no notice. Multiplied across a multi-thousand-yard job, the aggregate overcharge is significant.
Rebar specified by grade and diameter on the approved submittal. A lower grade or different size delivered and billed at the specified grade price. The invoice description reads "#5 rebar" — only the mill cert reveals the substitution, and the Ledger compares both.
Concrete specified at 4,000 PSI with a defined cement content. A 3,500 PSI mix or reduced cement content delivered — lower cost to the plant, same invoice price to you. On large structural pours, the cement content difference across hundreds of yards is a material cost discrepancy.
Ready-mix ordered and invoiced by the yard. Actual delivered volume less than billed — truck calibration, plant batching variance, or deliberate short-loading. Across a large project with many loads, a quarter-yard short per truck compounds into real money before the job closes.
Concrete plants added fuel surcharges during peak diesel price periods. Diesel normalizes. Surcharge remains on every delivery ticket as a standard line item — now structurally embedded in the per-yard price rather than tied to any actual fuel cost condition.
Accelerators, retarders, fiber reinforcement, and water reducers added at the plant and billed without an agreed price. On a complex structural pour with multiple admixture additions, unquoted add-on spend accumulates across every load with no individual ticket large enough to flag.
The Ledger produces a complete proof package for your concrete supplier relationships. Every discrepancy documented back to its source — delivery ticket, batch plant printout, rebar mill cert, admixture add-on. Quote. Invoice. Line item. Dollar amount.
Three commodity markets, one job, months of deliveries. The Ledger holds all of it simultaneously — the only way to see what no individual invoice ever shows.
Every overcharge sourced and documented. Hand it to your ready-mix plant, your rebar distributor, or your attorney — every number comes from their own tickets and your own quotes.
Every instance where what was delivered differed from what was specified — by PSI rating, cement content, rebar grade, or bar size. Documented and priced against the agreed specification.
Every admixture, every add-on, every surcharge billed without an agreed price — exported as a spreadsheet. Send it to your supplier. They now have to respond with formal pricing.
Your invoice price history mapped against BLS PPI for hydraulic cement and concrete reinforcing bar. See where your supplier's increases track the market — and where they don't.
Full methodology documentation structured for your attorney if the engagement requires legal proceedings — how every match was made, how every discrepancy was flagged.
