PANTAROCK 140

Liquid polymer for soil improvement in TBM applications

Item No. 0654

FIELDS OF APPLICATION

PANTAROCK 140 is a highly effective polymer specially designed to improve the performance in challenging ground conditions, e.g. in soils with high clay content and high fine content.

Furthermore it can be applied to alter the characteristics of bentonite slurries for slurry TMB applications.

PANTAROCK 140 has exceptional lubricating properties. It reduces the adhesion to the excavation tools during the excavation of soils exhibiting a sticky behaviour.

The highly efficient product is suitable for the following applications:

• Slurry TBMs
• EPB
• High clay content ground
• Modification of bentonite slurries

WORKING PRINCIPLE

PANTAROCK 140 is a high-quality liquid polymer providing the following effects:

In TBM applications

PANTAROCK 140 generates a plastic soil which can be easily excavated and transported.

In bentonite slurries

PANTAROCK 140 provides sufficient and entire wetting of bentonite particles even at low energy intakes. The admixture has slight retarding effects which prolongs the workability time and facilitates the pump ability.

DOSAGE | APPLICATION QUANTITY

PANTAROCK 140, used pure or in solution at concentration between 1 - 4% with the injected water.
