Schnabel Foundation Company

What Schnabel Foundation Company does

Schnabel Foundation Company is a privately held, design-build geostructural contractor founded in 1959 by Harry V. Schnabel Jr. and headquartered in Sterling, Virginia. The firm specializes in earth retention systems, deep foundations, and specialty ground-improvement solutions for complex U.S. infrastructure and building projects. Its service portfolio spans drilled shafts, secant piles, tiebacks, soil nailing, jet grouting, soil mixing, shotcrete, micropiles, aggregate piers, landslide stabilization, permanent retaining walls, and underpinning — delivered through eight or more design-build regional offices covering the Mid-Atlantic, Northeast, Midwest, Rocky Mountain, Southeast, Southwest, and West regions.

The company's technical differentiation rests on a portfolio of proprietary methods, most notably the patented Soil Mix Pier Underpinning (SMPU) system and a patent-pending Micropile/Pile Cap Underpinning System, supported by an in-house R&D and Equipment Division that fabricates custom tooling and operates a high-capacity specialized fleet including Bauer BG-33 and BG-28 rotary drill rigs. Customers include general contractors, construction managers, public agencies, and project owners across transportation, healthcare, advanced technology (data centers), commercial buildings, lodging and entertainment, tunnel shafts, wastewater treatment, waterfronts/dams/levees, non-commercial/historic, and industrial and power end markets; named engagements span St. Jude Children's Research Hospital, Piedmont Henry Hospital, Amazon Data Services, QTS Data Centers, Cleveland Guardians, ODOT, the University of Virginia, the National Park Service, and El Paso Water.

Schnabel generates revenue through project-based design-build contracts with no public pricing tiers; GTM is sales-led enterprise field sales with direct preconstruction engagement, supported by a project portfolio, case studies, safety/industry awards, and regional offices. The company is family-controlled — Hank W. Schnabel, the founder's son, retired in February 2025 after 36 years while remaining a major stockholder — with no disclosed external institutional investors, no parent company, and no M&A activity in the source data. Operational scale is evidenced by 6,000+ completed projects in 750+ U.S. cities and five consecutive ADSC Safety Awards (2021–2025).

Core offering

Schnabel is a design-build geostructural contractor that designs and constructs earth retention systems and specialty foundations for critical infrastructure projects. Its offerings span drilled shafts, secant piles, tiebacks, soil nailing, jet grouting, soil mixing, micropiles, underpinning, and landslide stabilization, delivered as integrated design-build solutions to general contractors, construction managers, and project owners across transportation, healthcare, data center, commercial, water, and historic preservation markets.

Product overview

Schnabel Foundation Company is a geostructural design and construction firm offering a comprehensive portfolio of geotechnical services for critical infrastructure projects nationwide. The company operates as a unified service provider rather than a software platform, delivering specialized construction solutions including drilled shafts, secant piles, tiebacks, soil nailing, jet grouting, soil mixing, landslide stabilization, and underpinning. Their proprietary Soil Mix Pier Underpinning (SMPU) system represents their patented technological differentiation, while specialized drilling equipment including Bauer BG-33 and BG-28 rigs support large-diameter foundation installation. Services span multiple markets including transportation, healthcare, commercial buildings, wastewater treatment, waterfronts/dams, and tunnel shafts, with projects completed in over 750 cities across the United States.

Products and services

• Drilled Shafts Large-diameter drilled shaft foundations providing deep structural support for buildings, bridges, and industrial structures.
• Aggregate Piers Ground improvement technique using compacted aggregate columns to enhance soil bearing capacity and reduce settlement.
• Excavation Support Temporary and permanent earth retention systems to support excavations for underground construction, foundations, and utilities.
• Jet Grouting Ground improvement method injecting high-pressure grout to create soil-cement columns for stabilization and groundwater cutoff.
• Landslide Stabilization Geotechnical solutions including tieback walls and soil nailing to stabilize slopes and prevent landslide movement.
• Micropiles Small-diameter drilled piles used for underpinning existing structures and providing load transfer to competent strata.
• Permanent Retaining Walls Long-lasting earth retention structures using soldier beams, tiebacks, and shotcrete for permanent slope support.
• Secant Piles Overlapping drilled shaft walls providing excavation support and groundwater cutoff for deep foundations and tunnels.
• Shotcrete Concrete application via pneumatic projection for slope facing, wall construction, and structural reinforcement.
• Soil Mixing
• Soil Nailing Reinforcement technique installing closely spaced steel bars (nails) into slopes or walls to provide passive lateral support.
• Tiebacks Anchored steel tendons drilled into competent soil or rock to provide lateral restraint for retaining structures.
• Underpinning Foundation strengthening techniques to support existing structures during adjacent excavation or construction.
• Soil Mix Pier Underpinning (SMPU) Patented underpinning technique creating soil-cement columns beneath existing foundations to reduce manual excavation requirements during underpinning operations.

Direct peers

• Hayward Baker (Keller Group): One of the largest North American geotechnical construction contractors; offers virtually identical services — earth retention, ground improvement, underpinning, and deep foundations — serving the same general contractor and owner base across the US.
• Berkel & Company Contractors: Specialty deep foundation and ground improvement contractor offering drilled shafts, micropiles, auger cast piles, and underpinning — directly overlapping Schnabel's core service portfolio and project types.
• Bauer Foundation Corp. US arm of German-based Bauer Group, supplying drilled shafts, diaphragm walls, and deep foundation services using Bauer drilling rigs (the same equipment platform Schnabel operates).
• Nicholson Construction Company: Specialty geotechnical contractor providing earth retention, micropiles, soil mixing, and ground improvement — overlap with Schnabel's drilled shafts, soil mixing, and tieback work for infrastructure and building projects.
• Subsurface Constructors: Mid-Atlantic specialty foundation contractor focused on drilled shafts, secant piles, and earth retention, with direct overlap on the geographic and service footprint where Schnabel operates.
• Moretrench Industrial: US specialty foundation contractor delivering dewatering, ground freezing, earth retention, and underpinning services; competes for the same complex geotechnical scopes on infrastructure and building projects.
• Helical Drilling Services: Northeast US specialty geotechnical contractor offering helical piles, drilled micropiles, and underpinning; competes on similar underpinning and shoring scopes in a shared geography.

Broad incumbents

• Trevi Group: Global specialty geotechnical and foundation contractor with a broad portfolio across foundations, ground improvement, and underground works; larger and more diversified than Schnabel, providing overlapping capabilities.
• Soletanche Bachy: One of the largest international geotechnical contractors offering deep foundations, ground improvement, and retaining structures; overlaps with Schnabel at the high end of complex earth retention and tunneling projects.

Emerging players

• Strata Geosystems: Innovation-led geosynthetics and soil reinforcement company whose products (soil nails, geogrids) intersect with Schnabel's slope stabilization and soil nailing work, representing an emerging technology alternative.
