What Inland Northwest Precast, Llc does

Inland Northwest Precast, LLC is a veteran-owned precast concrete manufacturer headquartered at 5204 N Starr Rd, Newman Lake, Washington, founded in 2018 in Spokane under the corporate umbrella of WM Winkler CO., a 106-year-old construction entity. The company operates an NPCA-certified plant producing seven core product lines: custom-engineered designs, drainage structures, electrical and utility vaults, light pole bases, manholes (Ø48"–Ø120"), tanks (septic, water, oil/water separators, grease interceptors), and ancillary products (bollards, grade adjustment risers, thrust blocks). Manufacturing follows a controlled-environment precast process — concrete is cast at the plant and transported for on-site installation — supported by internal QA/QC processes and custom-engineering design capabilities for engineer-specified municipal projects.

The company sells primarily to government and municipal buyers (WSDOT, ITD, City of Spokane, Spokane County, City of Post Falls/Hayden, Spokane International Airport, Mann-Grandstaff VA Medical Center) and to construction contractors across Washington, Idaho, Wyoming, and coastal Washington. Approved-supplier status with multiple state DOTs and municipalities is the primary access mechanism into public infrastructure bids. GTM is sales-led via phone (509-226-5050), email ([email protected]), and a website quote-request form, supported by Google Adsense, Bing Ads, and organic social on Instagram, Facebook, and LinkedIn. Pricing is quote-based with custom sizing available, and approved credit customers receive Net 30 terms. Distribution is supported by an in-house delivery fleet.

Revenue is undisclosed. The company self-describes as the "fastest growing precast company in the northwest." Sister company Pro-Recycle LLC supplies recycled concrete and asphalt aggregate, creating a closed-loop supply chain and an ESG-aligned sustainability narrative. No external institutional funding has been disclosed, and the company operates with 1–10 employees, suggesting a small but specialized regional player leveraging regulatory certifications and deep team expertise (200+ combined years) rather than scale.

Direct peers

• Utility Concrete Products: Midwest precast manufacturer specializing in utility, drainage, and infrastructure concrete products for municipalities and contractors. Comparable on product lineup (manholes, inlets, vaults) and sales-led, DOT/municipal customer focus.
• Jensen Precast: Multi-state precast manufacturer producing manholes, vaults, drainage, utility, and custom concrete products for municipal and infrastructure customers. Direct overlap with INW's product catalog, DOT-grade certifications, and sales-led go-to-market model targeting cities, counties, and DOTs.
• Tindall Corporation: Privately held precast concrete producer serving infrastructure, utility, and structural markets across the U.S. Southeast and Mid-Atlantic. Comparable in operating model (NPCA-style certified plant, custom engineering, DOT/municipal approvals) to INW but at greater geographic scale.
• Concrete Systems Inc. Pacific Northwest-based precast concrete producer serving utilities and municipalities with manholes, vaults, and drainage structures. Comparable operating geography, regulatory approvals, and product mix to INW; similar regional competitor for WSDOT/ITD and municipal bids.
• Wieser Concrete Products: Family-owned precast manufacturer of manholes, vaults, septic/wastewater tanks, and custom precast serving municipalities in the upper Midwest. Closely comparable on product catalog (tanks, manholes, vaults, drainage), customer type, and custom-engineering capability.
• Mack Industries: Family-owned precast concrete manufacturer producing manholes, utility vaults, drainage, and specialty structures for municipalities and contractors across the Midwest and Mid-Atlantic. Comparable plant-based, sales-led model and product mix to INW.

Regional players

• Columbia Precast Products: Pacific Northwest precast producer (Washington/Oregon) offering manholes, catch basins, utility structures, and custom precast. Closest geographic peer to INW, competing for the same WSDOT, city, and county projects in the Inland Northwest and greater PNW market.

Broad incumbents

• Oldcastle Infrastructure: National-scale precast and infrastructure products platform (CRH/Oldcastle) offering manholes, drainage, vaults, and utility structures. Direct catalog overlap with INW; serves as the dominant incumbent benchmark for pricing, certifications, and bid response times on the same municipal RFPs.
• Forterra: Large North American manufacturer of concrete and clay building products, including manholes, drainage structures, and utility/precast concrete. Overlaps with INW on the infrastructure/utility side of the catalog and competes on DOT-approved supplier lists.

Others

• Pro-Recycle LLC: INW's sister company under WM Winkler CO. that converts concrete and asphalt waste into recycled aggregate. Adjacent rather than competitive; included because it supplies INW with potential feedstock and represents the circular-economy positioning of the affiliated group.
