What BioSqueeze does

BioSqueeze is a biomineralization platform company that deploys low-viscosity fluids which infiltrate pores, fractures, and void spaces before forming structural calcium carbonate (limestone) in place through a controlled metabolic process. Headquartered in Butte, Montana, and operating across 13 U.S. states and 3 Canadian provinces, the company has completed over 400 commercial field deployments since 2019 and holds U.S. Patent 7,833,371 B2 covering its fluid systems and treatment methods. The platform addresses three engineering functions — strengthen (increase bearing capacity and stabilize unconsolidated materials), seal (reduce permeability and eliminate leakage pathways), and heal (repair fractures and reinforce cementitious infrastructure) — and is offered through a tiered product line of MacroSeal (1–10 mm gaps), MicroSeal (1 μm–1 mm gaps), and NanoSeal (sub-micron defects), all launched in January 2025.

The company's commercial foundation is oil and gas well integrity, where operators use BioSqueeze to remediate sustained casing pressure, surface casing vent flow, casing leaks, and well abandonment failures that conventional cement squeezes cannot resolve. BioSqueeze has expanded into Defense & Government (DARPA, U.S. Air Force Phase II programs, AFWERX TACFI, U.S. Army Corps of Engineers), Mining (mine dewatering, tailings stabilization, dust suppression), Civil Infrastructure (roadbeds, embankments, tunnels, bridges), and Environmental (groundwater containment, plume control, saltwater intrusion). The company reports a 90%+ recent field success rate across deployments and a claimed 100% field success rate for the three new products launched in 2025.

BioSqueeze operates a project-based professional services model with quote-based, treatment-specific pricing and 40+ customer Master Service Agreements in place. Revenue flows from oil and gas operators, U.S. government agencies (DoD/DARPA/Air Force), and infrastructure owners. The company has raised $7.4 million in Series A funding led by Valo Ventures (February 2023) and received more than $10 million in Department of Defense development funding. It is led by President & CEO Mark Ranalli alongside founder and VP R&D Randy Hiebert, and has built a regional operating structure including a BioSqueeze Canada subsidiary serving the Western Canadian Sedimentary Basin.

Core offering

BioSqueeze delivers subsurface biomineralization treatment services that use low-viscosity fluids injected into pores, fractures and void spaces, where a controlled metabolic process forms structural limestone (calcium carbonate) in place to seal, strengthen, and heal subsurface systems. The platform is commercialized through three product lines—MacroSeal (1–10 mm gaps), MicroSeal (1 µm–1 mm gaps), and NanoSeal (sub-micron defects)—and is sold as project-based engineering services to oil and gas operators, government agencies, and infrastructure owners under Master Service Agreements.

Product overview

BioSqueeze is a biomineralization platform company offering subsurface engineering solutions through three core product lines: MacroSeal™ (for 1-10 mm gaps), MicroSeal™ (for 1 μm–1 mm gaps), and NanoSeal™ (for sub-micron defects). The platform uses low-viscosity fluids that enter pores, fractures and void spaces, then form structural limestone in place through a controlled metabolic process. The platform serves three engineering functions—Strengthen, Seal, and Heal—across five major markets: Energy (oil and gas wells), Defense (military infrastructure), Mining, Infrastructure, and Environmental applications.

Partnerships

Four partnerships are on record, tiered core and minor.

• U.S. Department of Energy (DOE)coreStrategic or Co-development PartnerBioSqueeze developed its biomineralization technology in partnership with the Department of Energy. This collaboration contributed to achieving over 90% success in sealing wells since 2019. The DOE partnership provided technical validation and development support for the company's core well-integrity remediation platform.
• DARPA (Defense Advanced Research Projects Agency)coreStrategic or Co-development PartnerDARPA invested $3.8 million through its SBIR XL program to advance biomineralization for soil and sand stabilization. The program culminated in a full-scale Camp Lejeune demonstration. DARPA program manager Matthew Pava publicly characterized BioSqueeze's translation of biomineralization into biocement as a success story for deployable infrastructure in difficult-to-reach locations.
• U.S. Air Force (Phase II Programs)coreStrategic or Co-development PartnerThe U.S. Air Force completed two Phase II development programs applying biomineralization to rapid airfield crater repair and subgrade stabilization beneath existing airfield pavement. A subsequent AFWERX TACFI award of approximately $2 million (selected July 2026) is bridging successful prototype development toward operational scaling and procurement transition.
• U.S. Army Corps of Engineers — Engineer Research and Development Center (ERDC)minorStrategic or Co-development PartnerThe U.S. Army Corps of Engineers' ERDC independently evaluated the Camp Lejeune full-scale field demonstration and reported that the technology exceeded expectations. This independent validation supports the transition of the platform toward defense procurement.
