What CarbonBuilt does
CarbonBuilt is a U.S. climate-tech company that develops and commercializes ultra-low-carbon concrete technology for the building-materials industry. Founded in 2020 as a spinout of UCLA's Institute for Carbon Management (where the underlying research began in 2012 under Dr. Gaurav Sant), the company is headquartered in Los Angeles with a fully-owned manufacturing facility in Danielson, Connecticut acquired from Jolley Concrete and Block in February 2025. CarbonBuilt won the NRG Cosia Carbon XPRIZE in 2021 and became the first company in the world to begin commercial production of ultra-low-carbon masonry in 2023.
The company's core product is Reversa®, a proprietary concrete binder composed primarily of upcycled industrial byproducts that replaces up to 50% of traditional cement in concrete masonry and hardscapes. During the curing process the binder reacts with CO2 to enable permanent carbon sequestration, and the company states the technology can achieve up to 70% carbon-footprint reduction versus conventional production while maintaining price parity and meeting ASTM performance standards (C-90, C-129, C-1372). Product lines include loadbearing and non-loadbearing concrete masonry units (CMU), architectural masonry (ground/split/smooth face), segmental retaining wall systems (Versa-Lok Standard and Square Foot), and resale products such as Ideal Pavers, Glen-Gery Brick, and QUIKRETE concrete mix.
CarbonBuilt operates a dual revenue model: (1) direct hardware sales of finished concrete masonry and hardscapes manufactured at its Danielson, CT plant, sold at price parity to conventional concrete via direct sales and channel partners (including Alley-Cassetty) to building owners, architects, general contractors, masons, and distributors across the Northeast and Southeast U.S.; and (2) licensing and technology-deployment of the Reversa® binder to third-party concrete masonry plants (e.g., Blair Block in Alabama, ACME Brick & Block), generating licensing/royalty revenue. Pricing is unit-based with pay-as-you-go billing, with the company explicitly marketing on the "Same Price. Same Performance. Less Carbon." positioning.

Revenue model
- Ultra-Low Carbon Concrete Product Sales: CarbonBuilt generates revenue by manufacturing and selling ultra-low carbon concrete masonry products (Concrete Masonry Units, Architectural Masonry, Segmental Retaining Walls) and hardscapes produced at its fully-owned facility in Danielson, CT. Products are sold at price parity to conventional concrete products, with the company's normal weight masonry carrying the lowest carbon footprint in the U.S. per EC3. The company also sells Resale Products including Ideal Pavers, Glen-Gery Brick, QUIKRETE® concrete mix, and masonry accessories.
- Reversa® Binder Licensing/Technology Deployment: CarbonBuilt deploys its proprietary Reversa® binder technology at partner manufacturing plants, generating revenue through technology licensing and binder supply arrangements. First commercial contract signed with Blair Block in Alabama in 2022.

CarbonBuilt product offering
Product offeringCore offering
CarbonBuilt manufactures and sells ultra-low carbon concrete masonry and hardscapes (CMU, architectural masonry, segmental retaining walls) produced with its proprietary Reversa® binder that replaces up to 50% of traditional cement with upcycled industrial byproducts and sequesters CO2 during curing, achieving up to 70% carbon reduction at price parity with conventional concrete. The company also deploys the Reversa® binder via licensing and supply agreements at partner concrete plants, in addition to reselling complementary building materials such as pavers, brick and concrete mix.
Product overview
CarbonBuilt is an ultra-low carbon concrete technology company that produces deeply decarbonized concrete masonry and hardscapes. The company's core offering is the Reversa® proprietary binder technology, which replaces up to 50% of traditional cement with upcycled industrial materials and achieves up to 70% carbon footprint reduction. CarbonBuilt operates manufacturing facilities (including the acquired Jolley Concrete plant in Danielson, CT) producing concrete masonry units, architectural masonry, segmental retaining walls, and related products — all using the Reversa® binder while maintaining price parity and performance equivalent to conventional concrete. The company also resells complementary building materials including pavers, brick, and concrete mix products.

CarbonBuilt partnerships and signals
Strategic signalPartnerships
Three partnerships are on record, tiered supporting, core and foundational.
- Sterling Concrete Corp.supportingSterling Concrete Corp., a ready-mix concrete supplier based in Massachusetts, acquired the ready-mix operation from CarbonBuilt as part of the Jolley Concrete acquisition transaction. This was a divestiture of the ready-mix portion of the Jolley Concrete business.
- Alley-CassettycoreAlley-Cassetty is a distribution partner for CarbonBuilt products, listed as a partner on the CarbonBuilt website. The partnership enables broader distribution of CarbonBuilt's ultra-low carbon concrete products in the market.
- UCLA Institute for Carbon ManagementfoundationalCarbonBuilt originated from foundational research at UCLA's Institute for Carbon Management led by Dr. Gaurav Sant in 2012. The company was spun out from UCLA to scale the technology developed at the institute.

CarbonBuilt competitors and assessment
Company assessmentBroad incumbents
- CRH plc: CRH is a major building materials producer operating across cement, aggregates, and concrete products in North America — including the Oldcastle APG division where CarbonBuilt's CCO previously served as President.
- Cemex: Cemex is a global cement and ready-mix concrete leader with a Vertua low-carbon product line. Its scale and distribution could quickly overwhelm CarbonBuilt's regional Northeast presence if it localizes competing products.
- Holcim: Holcim is one of the world's largest cement and aggregates producers with a growing low-carbon concrete product line (e.g., ECOPact). As a broad incumbent with global scale, Holcim represents both a major competitor and potential channel/licensing partner for CarbonBuilt's technology.
- Vulcan Materials: Vulcan Materials is the largest U.S. producer of construction aggregates and a major concrete products manufacturer, with growing interest in lower-carbon concrete offerings serving the same customers CarbonBuilt targets.
Direct peers
- Partanna: Partanna produces carbon-negative concrete using industrial byproducts and a proprietary binder. CarbonBuilt's CMO Brian Bush previously held a senior manufacturing role at Partanna, indicating the two companies operate in the same low-carbon concrete technology space.
- Brimstone: Brimstone (formerly CarbonCure Cement) manufactures carbon-negative Portland cement from calcium silicate produced using carbon-free processes — directly competing with CarbonBuilt's approach of replacing traditional cement with low-carbon binders.
- Solidia Technologies: Solidia uses a CO₂-cured concrete process that sequesters carbon during the curing phase — mechanistically similar to CarbonBuilt's Reversa® binder approach. Both companies commercialize CO₂-cured concrete masonry and building products.
- CarbonCure Technologies: CarbonCure injects captured CO₂ into ready-mix concrete during mixing, directly competing with CarbonBuilt's approach of reducing cement content and infusing CO₂ during curing. Both target the same low-carbon concrete value proposition for developers and concrete producers.
Emerging players
- Carbon Upcycling Technologies: Carbon Upcycling produces CO₂-upcycled supplementary cementitious materials (SCMs) and concrete additives. Their technology overlaps with CarbonBuilt's use of industrial byproducts and CO₂ to displace traditional cement content.
- Sublime Systems: Sublime Systems is an MIT-spinout developing low-carbon cement using electrochemical processes. While focused on cement rather than finished masonry, Sublime addresses the same cement-industry decarbonization thesis that CarbonBuilt attacks through binder replacement.
