Concrete companies in Austin: 265 locations, 73 permitted plants and the city's right-of-way license

This report is for Austin-area homeowners, builders and developers choosing a concrete contractor or supplier, and for B2B sellers whose customers are concrete firms: equipment dealers, admixture and fiber suppliers, testing labs, fleet and dispatch software, insurers and recruiters.

Two public lists worth knowing

Plants: the state's concrete production permits. Ready-mix and concrete product plants in Texas that discharge process wastewater or stormwater need coverage under the Texas Commission on Environmental Quality's general permit TXG110000. TCEQ publishes active authorizations as open data. In the five metro counties, as updated on 29 October 2026:

The operators with the most authorizations are Tex Mix Partners (13), Texas Materials Group (12), Lauren Concrete (11), Alamo Concrete Products (7) and Centex Materials (6). The list includes block and precast plants as well as ready-mix, and a plant with no discharge may not appear.

Crews: the city's right-of-way contractor licenses. The City of Austin requires contractors doing driveway and sidewalk work in the public right-of-way to hold a right-of-way contractor license, backed by a $10,000 bond, insurance, a resolution of authority and an authorized agent form. The license stays valid until the bond or insurance on file expires. The city publishes the active holders: 462 on 30 October 2026, of which 73 have "concrete" in the business name. Excavation and utility contractors hold the same license, so the full list is broader than concrete.

The market in Census data

Figures for the Austin-Round Rock-San Marcos, TX Metro Area (CBSA 12420), combining NAICS 238110 (Poured Concrete Foundation and Structure Contractors) and NAICS 327320 (Ready-Mix Concrete Manufacturing). Source: US Census Bureau, County Business Patterns 2023.

The contractor figure for 250 or more is the 207 total less the published classes. One ready-mix establishment sits in a class the Census Bureau doesn't publish. Six ready-mix locations with 100 to 249 employees is a lot for a metro this size; plants here run big fleets.

Two county employee totals were published but flagged as high-noise (confidentiality noise moved them by 5% or more), so we leave them out. By code, Williamson has 49 contractors and 20 ready-mix establishments; Hays has 33 and 8.

These counts are establishments with paid employees, not companies, and they leave out owner-operators without payroll. A producer with ten plants counts ten times.

Ownership at the top of the market

Two public companies' filings describe big Austin-area assets:

• CRH (NYSE: CRH). On 9 February 2024 it bought Martin Marietta's South Texas cement business for $2.1 billion: the Hunter cement plant in New Braunfels, its terminals and 20 ready-mix plants serving the Austin and San Antonio region (both companies' 10-Ks).
• Eagle Materials (NYSE: EXP, Dallas). It owns 50% of Texas Lehigh Cement, whose plant is in Buda in Hays County, with Heidelberg Materials as its partner, and ran 11 ready-mix plants in central Texas at 31 March 2026 (its 10-K for the year to that date).

No SEC-registered listed concrete company is headquartered in the metro itself.

Hiring a crew: what the city checks

Worked example: putting three flatwork bids on the same basis

Illustrative example. The bids are invented to show the arithmetic.

A Pflugerville homeowner gets three bids for a 600 square foot patio and walk.

Concrete for 600 square feet at 4 inches is 600 × (4 ÷ 12) ÷ 27 = 7.4 cubic yards; at 5 inches it's 9.3, about 25% more material. Once demolition is added to Bid B, the "cheapest" quote is the middle one, and Bid C's premium buys a thicker slab, not just a higher margin.

Selling to Austin concrete firms

Start with the two lists: 23 permitted plant operators and the city's right-of-way licensees. Plants buy drivers, trucks, parts, admixtures and dispatch software; flatwork and foundation crews buy screeds, curb machines, forming and pumps. Fast growth in Williamson and Hays counties means new plants and new crews, so date the list and refresh it each quarter. For list building, see how to build a prospect list. Bebop can find concrete firms matching a description like this and research each account.

Illustrative example. A dealer of used slipform curb machines (hillcountrycurb.example) targets the 73 concrete-named right-of-way licensees. One owner or superintendent at each is 73 contacts; at an 8% reply rate that's about 6 conversations, and two machine sales at $95,000 is $190,000.

Subject: Curb machine for your city work

Hi [first name],

[Company] holds a City of Austin right-of-way license, so I'm guessing curb and sidewalk work is a steady part of your year.

We have two reconditioned slipform curb machines ready to demo in [location], with a 90-day parts warranty.

Want photos and hours on both?
