What Drill Tech Drilling and Shoring, Inc. does

Drill Tech Drilling and Shoring, Inc. is a privately held specialty geotechnical construction contractor headquartered in Antioch, California, founded in 1994 by two friends and their spouses as a two-man operation and grown into a nationwide firm with 600+ employees and 10+ offices spanning California to Maryland. The company self-performs six integrated service lines — earth retention systems, ground treatment and ground improvement, deep foundation systems, architectural shotcrete, mining and tunneling excavation support, and railroad-compliant excavation and shoring — supported by in-house engineering capabilities that connect design drafting with field execution across transportation, water, rail, mining, and heavy civil infrastructure projects.

The firm generates revenue project-by-project through competitive bidding on specialty geotechnical scopes, with disclosed individual contract values ranging from the millions up to $53.4M (Ventura 01 Slope Restoration), $53M (Anderson Dam Tunnel), and $30.3M (Oroville Spillways Emergency). Drill Tech serves two primary customer segments: (i) public owners and developers undertaking complex infrastructure projects (Caltrans, California Department of Water Resources, Santa Clara Valley Water District, and similar agencies across 45+ states), and (ii) general contractors seeking a single specialty geotechnical subcontractor able to handle multiple scopes under one contract. Distribution is exclusively direct — competitive bidding to GCs and public agencies, plus joint venture arrangements with prime contractors (e.g., Flatiron-Drill Tech JV) — with no self-serve or marketplace channels. Marketing relies on project portfolio credibility, industry certifications (ACI, AEG, Highwire Gold, ISN), and 15 consecutive years of ENR Top 20 Excavation Contractor ranking rather than digital acquisition. The firm holds 20+ state contractor licenses and has completed 2,500+ projects over 30+ years of operations, operating as a founder-owned, family-culture enterprise with no disclosed institutional investors or parent company.

Revenue model

1. Geotechnical Construction Project Delivery: Drill Tech generates revenue as a specialty geotechnical contractor on a project-by-project basis. Revenue is derived from executing specialized scopes including earth retention, ground treatment, foundations, shotcrete, mining/tunneling, and rail work. Projects are awarded through competitive bidding to owners and general contractors, with contract values ranging from millions to over $50M per project.
2. In-House Engineering Services: Engineering support for drafting plans and designs for safe and reliable builds is integrated into project delivery, bundled within overall project scope rather than sold as a separate engineering services line.

Functional benefit

Products and services

• Earth Retention Systems Engineered earth retention systems designed to stabilize lateral earth pressures, control movement, and drain potential water pressure for both permanent structures and temporary shoring during excavation projects. Delivered to government agencies, general contractors, and private developers on infrastructure, transportation, water, rail, and mining projects.
• Ground Treatment and Ground Improvement Ground treatment services that improve ground strength and stabilize loose soil for seismic stabilization, increased bearing capacity, and mitigation of liquefiable soils. Targeted at sites where bearing capacity, settlement, or seismic considerations affect project outcomes.
• Foundations and Deep Foundation Systems Deep foundation systems designed to transfer structural loads to stronger soil or rock below the surface, accounting for axial loads, lateral loads, uplift force resistance, and settlement control. Used to support weak soil conditions on heavy civil and infrastructure projects.
• Architectural Shotcrete Air-sprayed concrete sculpted and stained to resemble natural rock, used as an aesthetic finished facing for retaining walls in highway construction, landslide repair, roadway widening, bluff erosion repair, and commercial or residential developments.
• Mining and Tunneling Services Excavation and support services for tunnels and shafts, including new tunnel construction, portal construction, mine infrastructure, declines, and rehabilitation of existing tunnels. Delivered for pipeline, water, and mining infrastructure projects.
• Rail Construction Services Railroad-compliant excavation and shoring services using specialized equipment and experience for projects with strict operating constraints and limited work windows near active tracks. Delivered to rail clients and contractors executing rail infrastructure projects.
• In-House Engineering Services Specialized engineering support providing drafting plans and designs for safe and reliable geotechnical construction builds, connecting design and field execution within the integrated project delivery model.
