Fields of application

PANTAROCK 141 is a highly effective anti-clay polymer specially designed to improve the performance of TBM tunnelling in clayey soils. The use of PANTAROCK 141 can lead to the following benefits:
>  Exceptional lubrication properties
>  Reduced clogging and adhesion on the cutter head
>  Easy excavation and transport
>  Increased productivity of TBM
>  Optimised advance rates
>  Reduced abrasiveness at the cutter head, screw conveyor and conveyor which can lead to
>  Decreased wear costs and
>  Lower replacement frequencies
>  Facilitated soil extraction and conveyance
>  Effective pressure control
>  Reduced permeability
>  Easier ‘mucking’

Working principle

The anti-clay polymers of PANTAROCK 141 generate a plastic soil with excellent lubricating properties. The soil can be easily excavated and transported.
