LIQUID-APPLIED SPOILS SOLIDIFICATION FOR MODERN EPB-TBM OPERATIONS

The MF LiquidTech™ family was developed for projects requiring the operational flexibility of liquid-applied spoils solidification systems. The platform is designed to support improved reagent distribution, rapid homogenization, free-water reduction, and spoils handling improvement under variable EPB tunneling conditions.

The MF LiquidTech™ platform provides an alternative to dry powder application systems for operations preferring liquid reagent integration into existing TBM injection or spoils management processes.

Built for EPB-TBM Liquid Reagent Operations

The MF LiquidTech™ family was developed for EPB-TBM operations requiring liquid-applied spoils solidification under variable tunneling conditions.

The platform is designed to support:

Reduced free-water release

Reduced flowable spoils behavior

Improved reagent distribution through liquid application

Improved spoils handling during hauling and temporary storage

Improved spoils transportability

Operational flexibility for liquid injection systems

Improved spoils management consistency under variable field conditions

Dosage rates and operational performance may vary depending on spoils moisture conditions, clay fraction, spoils behavior, and required spoils handling characteristics.

Engineering & Operational Considerations

Performance ranges presented throughout this page are intended to support simplified product selection for typical EPB-TBM tunneling conditions.

Moisture content, spoils behavior, clay content, and operational requirements may influence final product performance and dosage rates.

MF LiquidTech™ products are intended for spoils solidification and free-water reduction in EPB-TBM operations. Final spoils handling, transportation, and disposal requirements remain dependent on project conditions and local regulations.

The MetaFLO technical team can assist in determining which MF LiquidTech™ platform may be more suitable for specific EPB-TBM muck conditions and operational objectives.
