Revenues And Gross Profit [Abstract] |
Total Revenues and Gross Profit (Loss) by Product Line | The following tables, which are reconciled to consolidated amounts and reflect continuing operations only, provide revenues and gross profit (loss) by line of business: Building Materials (further divided by product line) and Specialties. Effective September 30, 2025, the Company combined the cement and ready mixed concrete and the asphalt and paving services product lines (hereinafter, other building materials). The change was driven by the reduced significance of each of these product lines relative to consolidated revenues from continuing operations and consolidated income from continuing operating results as a result of the pending divestiture of the Company's Midlothian cement plant, related cement terminals and Texas ready mixed concrete plants (see Note 2) and associated reclassification of these revenues and income to discontinued operations for all periods presented. Interproduct revenues represent sales from the aggregates product line to the other building materials product line.
