Graniterock’s EPD footprint across concrete, asphalt, aggregates

5 min read
Published: December 19, 2025

Graniterock is a California mainstay in heavy building materials. Specifiers increasingly want proof, not promises, which means product‑specific EPDs that keep bids competitive and carbon math clean. Here is how their portfolio maps to declarations today, and where topping up coverage would unlock more specs tomorrow.

Company snapshot

Graniterock supplies ready‑mix concrete, hot‑mix asphalt, and construction aggregates across Northern and Central California. They also market recycled materials and specialty mixes for paving, flatwork, and structural work. Think of them as the one‑stop yard where a GC can load up a whole job’s hardscape.

Product range and rough scale

Across plants, Graniterock offers several product families and hundreds of individual SKUs. Ready‑mix alone spans everything from lean CDF to high‑strength structural designs. Asphalt covers common Caltrans mixes for roadway and parking applications. Aggregates run the gamut from base rock to manufactured sand.

Concrete EPD coverage: strong and deep

Graniterock maintains a large library of mix‑specific concrete EPDs across multiple plants. Listings appear under the ASTM International program and reflect current PCRs used for concrete. The volume is measured in the hundreds, which gives project teams broad freedom to match submittals to mix designs without re‑work (ASTM International EPD Program, 2025).

Analogy time. If a PCR is Monopoly’s rulebook, these plant‑level EPDs are the individual property cards. Easy to pull, easy to play, and they speed up approvals when schedules are tight.

Asphalt EPD coverage: present, with room to grow

Graniterock also publishes asphalt mixture EPDs. These are visible on the National Asphalt Pavement Association’s Emerald Eco‑Label directory and show validity horizons consistent with current Caltrans work. The set is modest compared with concrete, so expanding to more mix classes and plants would help win tightly specified roadway work (NAPA Emerald Eco‑Label, 2025).

Aggregates: the notable gap

We could not verify current public EPDs for core aggregate products like base rock or sand. That is understandable given historical priorities, yet it is increasingly a blind spot when owners request whole‑package transparency. When aggregates lack declarations, teams often must model with conservative defaults, which nudges buyers toward suppliers that bring full paperwork.

Why the gap matters commercially

On projects chasing emerging LEED v5 goals and owner carbon targets, a product without a product‑specific EPD can carry a penalty in the carbon accounting. That makes substitutions more likely and slows approval. The price of one EPD is frequently earned back with a single mid‑sized win, and the avoided churn alone is worth it when crews are mobilized. It sounds obvious, but it is definitly where bids are won or lost.

Likely competitive set

Graniterock often lines up against CalPortland, CEMEX, Central Concrete in ready‑mix, Vulcan Materials and Teichert in aggregates, and regional asphalt producers serving the same Caltrans districts. Many of these peers maintain broad concrete EPD libraries and a growing set of asphalt EPDs. Some are starting to publish aggregate EPDs, which can tilt preference on campus, healthcare, and municipal work where low‑carbon specs are spreading.

A practical playbook for the next 90 days

  • Prioritize aggregate EPDs for top‑volume base rock and sand at high‑throughput quarries, then add recycled aggregate variants. Start with the plant that feeds the most Caltrans or municipal bids.
  • Round out asphalt EPDs so each primary plant has declarations for its standard Caltrans mixes and at least one warm‑mix option.
  • Keep concrete fresh by renewing mixes within six to twelve months of expiry and ensuring high‑leverage structural and pump mixes are covered at every active plant.

Publishing choices that keep you flexible

Program operator choice should fit the product and audience. ASTM International, NRMCA, and NAPA are all common for these categories in the US. The best partner makes data collection painless, aligns the PCR choice with competitors, and publishes where specifiers actually look. That white‑glove rigor is what shortens timelines and reduces back‑and‑forth on submittals.

The takeaway for specability

Graniterock’s concrete EPD bench is a strength, asphalt coverage exists, and aggregates are the clear opportunity. Closing that last gap turns a good submittal package into a complete one, which is what wins work when owners want low‑carbon materials without extra homework.

Frequently Asked Questions

How many individual Graniterock concrete mixes appear to have EPDs today?

Hundreds across multiple plants, based on program listings rather than exact counts (ASTM International EPD Program, 2025).

Do Graniterock asphalt mixes have published EPDs?

Yes, several mixes appear on the NAPA Emerald Eco‑Label directory and show current validity windows suitable for public‑works bids (NAPA Emerald Eco‑Label, 2025).

Are there public EPDs for Graniterock aggregates like base rock or sand?

We could not verify current, public aggregate EPDs. This is a high‑value place to start because many owners now request full‑package declarations for major material lots.
