23811

Analysis

NAICS 23811 is the 2022 NAICS industry for poured concrete foundation and structure contractors, part of 2381 (Foundation, Structure, and Building Exterior Contractors).

It has only one more detailed code, 238110, which covers exactly the same activities; the definition, index entries and statistics are on that page.

Between 2018 and 2023 the number of establishments grew 12% and employment rose 11%. The 2018 count used NAICS 2017, so part of a large move can come from codes being redefined rather than from businesses opening or closing.

County Business Patterns counts 23,350 US establishments in this code in 2023, employing 272,692 people at an average annual payroll of $70,546 per employee (53rd percentile of national industries). 59% of the establishments have fewer than five employees, which is close to the national mix.

By establishments it ranks 2nd of the 8 codes at this level within Foundation, Structure, and Building Exterior Contractors, with 22% of them.
