What Rosch Company does

Rosch Company is a privately held specialty construction services firm founded in 1991 by Scott C. Rozier as SCR Contracting Company in the St. Louis area. The company designs, engineers, and installs retaining wall systems and unit paver / hardscape solutions, operating across three regional divisions in the Midwest (Chesterfield, MO), Southwest (Round Rock, San Antonio, and Allen, TX), and West (Denver, CO), with project delivery reported in over 20 U.S. states. Rosch serves commercial developers, residential homeowners and homebuilders, heavy highway and municipal clients, government agencies (federal, state, and local), healthcare providers, educational institutions, and industrial customers such as Amazon.

The company's core technical offering spans modular block walls (using brands including Versa Lok, Keystone, Allan Block, Rockwood, Anchor, and Omega), mortared limestone walls (native to the Southwest), Mechanically Stabilized Earth (MSE) walls capable of structures exceeding 60 feet, and a comprehensive paver / hardscape portfolio (permeable unit paving, clay and concrete unit paving, pedestal paving, natural stone paving, and pool decks). Engineering is performed in-house through ROSCH Engineering (formed in 2012 from the Ettamar Engineering acquisition), delivering design-build drawings, value engineering, soils design, and global stability analysis. The company's stated competitive differentiators are scale (one of the largest retaining wall contractors in the U.S. with over 10 million square feet installed), integrated design-build delivery, nationwide buying power, and a state-of-the-art equipment fleet.

Rosch generates project-based revenue from construction contracts and engineering services, with pricing quote-driven and varying by project scope, materials, and site conditions. Customer acquisition is primarily through direct enterprise sales, competitive bidding on government and heavy-highway work, and industry referrals. The company has historically been acquisitive, including the 2012 Ettamar Engineering transaction and the 2023 acquisition of Retaining Wall Solutions, Inc. Its founder Scott Rozier remains CEO-President, with John Andrzejewski promoted from COO to President in 2024 as part of leadership succession layering. No external private equity or venture capital backing is evident in the available data.

Direct peers

• Unilock: North American manufacturer of concrete pavers and segmental wall systems with a certified contractor installer base. Comparable as a competing hardscape/wall system brand with overlapping commercial and residential specifications.
• EP Henry: Mid-Atlantic hardscape manufacturer offering pavers, walls, and outdoor living products via contractor partners. Comparable as a regional paver/wall brand competing for similar residential and commercial hardscape specification work.
• Redi-Rock International: Manufacturer of large-block retaining wall systems with a network of certified installers. Comparable because Redi-Rock is one of the dominant wall system brands Rosch installs and competes with on commercial gravity-wall projects.
• Versa-Lok (Westblock Systems): Manufacturer of segmental retaining wall systems used in both commercial and residential applications. Comparable because Versa-Lok is one of the named modular block brands Rosch installs at scale across its three regions.
• Allan Block Corporation: Manufacturer of segmental retaining wall systems with a national certified installer network. Comparable as another major modular block OEM competing for the same commercial/residential wall specification market.
• Keystone Retaining Wall Systems: Segmental retaining wall block manufacturer owned by CRH/Oldcastle. Directly comparable as one of the modular block brands (alongside Versa-Lok and Allan Block) that Rosch specifies and that competing installers also use.
• Anchor Wall Systems (CRH): Segmental retaining wall manufacturer, part of the CRH/Oldcastle building products portfolio. Comparable as another block brand Rosch installs and as a sister product line to Keystone within CRH.
• Belgard (CRH/Oldcastle APG): National hardscape/paver manufacturer with a contractor-dealer network. Comparable because Belgard pavers are commonly specified in commercial hardscape bids alongside Rosch's installation services.

Broad incumbents

• Tensar International: Manufacturer of geosynthetics used in MSE wall systems and site stabilization for heavy civil/highway projects. Comparable because Tensar products are specified inside the MSE wall work Rosch performs for DOTs and large developers.

Emerging players

• Techo-Bloc: Manufacturer of premium concrete pavers and segmental walls serving residential and light commercial hardscape markets. Comparable as a competing hardscape brand increasingly specified in higher-end residential and outdoor living projects where Rosch also competes.
