MF GeoDry™ - Cost-Optimized EPB-TBM Muck Solidification and Free-Water Control

MF GeoDry™ is a family of engineered dry reagents developed specifically for EPB-TBM tunneling operations requiring spoils solidification, free-water reduction, and improved spoils handling performance.

MF GeoDry™ helps reduce free-water release, reduce flowable spoils behavior, improve spoils stackability, and improve spoils handling during hauling and temporary storage operations.

MF GeoDry™ 001 is designed for tunneling spoils with relatively stable moisture conditions and lower levels of free water, where consistent material conditioning and basic solidification performance are required.

MF GeoDry™ 002 was developed for more demanding and variable tunneling conditions, including spoils with higher moisture fluctuations, elevated free-water content, and more difficult handling characteristics. It provides enhanced free-water absorption and broader operational flexibility under changing field conditions.

Unlike traditional lime or cement-based spoils solidification additives, MF GeoDry™ was specifically engineered for EPB-TBM spoils solidification applications requiring improved handling efficiency and cost-optimized performance. MF GeoDry™ typically achieves effective solidification at significantly lower dosage rates and with faster reaction times, helping reduce material consumption, simplify logistics, and accelerate spoils handling operations.

MF GeoDry™ products were specifically engineered for EPB-TBM spoils solidification applications, taking into account the unique rheological behavior and variable moisture characteristics commonly associated with tunneling spoils and conditioned excavated materials. The products are typically evaluated for spoils streams presenting flowable behavior, free-water release during hauling or stockpiling, and spoils handling challenges associated with wet spoils conditions.

Typical dosage rates vary depending on moisture content, spoils behavior, clay fraction, and operational objectives.

• GeoDry 001 Typical dosage rates between 0.15–0.35%
• GeoDry 002 Typical dosage rates between 0.1–0.30%
