NEW PRODUCT LINE — ENGINEERED FOR MODERN EPB TUNNELING OPERATIONS

Designed for tunnel boring machine (TBM) operations operating in low to moderate moisture conditions, the MF GeoDry™ helps tunneling contractors improve excavated material handling, reduce muck hauling challenges, and stabilize EPB spoil directly at the discharge point.

Unlike traditional solidification methods such as lime, cement, sawdust, or generic SAPs, the MF GeoDry™ family represents MetaFLO’s Third Wave of Solidification: engineered solutions tailored specifically for modern underground infrastructure projects, municipal tunneling operations, and North American TBM excavation environments.

Clay contents or higher

The GeoDry™ family was developed to support:

EPB muck conditioning

Tunnel spoil stabilization

Free-water reduction

Improved excavated material handling

Muck hauling optimization

Reduced spoil disposal costs

Improved landfill disposal efficiency

Stockpiling efficiency

Improved handling characteristics

With rapid reaction times and low dosage requirements, MF GeoDry™ products help transform semi-fluid tunnel spoil into non-flowable and, in many cases, stackable muck suitable for hauling, temporary storage, and more economical disposal operations.

Typical application rates generally range from approximately 0.1% to 1%, depending on geology, clay content, moisture conditions, and desired handling characteristics.

Built for real North American tunneling conditions

The MF GeoDry™ family was engineered specifically for the operational realities of North American tunneling contractors working in:

Subway tunneling

Sewer tunneling

Utility tunnel excavation

Water infrastructure projects

Wastewater infrastructure

Transportation tunnel construction

Municipal underground infrastructure

Civil underground construction

Technical requirements and project-specific operational conditions may influence achievable performance results. Consult MetaFLO’s technical team for project-specific evaluation and validation requirements.

Engineering & Operational Considerations

Performance ranges and operational recommendations presented throughout this page are intended to support simplified product selection for typical EPB tunneling environments.

Project-specific geology, mineralogy, moisture conditions, clay composition, operational objectives, and combined limiting factors may influence final product performance and achievable spoil handling characteristics.

In more challenging tunneling environments — including combinations of high moisture content, low clay percentage, elevated calcium content, or projects requiring stackable spoil performance — additional technical evaluation, mineralogical review, or bench-scale validation testing may be recommended by the MetaFLO technical team.

Performance validation requirements may vary depending on project conditions and desired operational outcomes.

Contact MetaFLO Technologies to discuss project-specific technical validation and conditioning recommendations.
