Soil Conditioning & Fluidizing Additive
SUPER MUD-WC
SUPER MUD-WC is a soil fluidizing additive for EPB and shield TBM operations, designed to enhance the plastic flow of excavated soil while providing effective water control under groundwater pressure. Especially in cohesive soils such as clay, it helps prevent face clogging and improves conditioning performance at the tunnel face.
Product Features
-
1
Easy Water Content Control with Low Dosage
Unlike conventional bentonite systems requiring large volumes, SUPER MUD-WC allows easy water content control with a small dosage, simplifying on-site application.
-
2
Enhanced Face Stability
Forms a plastic and stable soil structure, minimizing dewatering and free water separation while maintaining uniform face conditions and preventing face collapse.
-
3
Reduced Friction & Cutter Torque
Improves soil flowability and prevents chamber clogging, reducing friction, cutter torque, and mechanical load on the TBM.
-
4
Thixotropic Stability for Muck Handling
Suppresses soil sedimentation and prevents blockage in pipelines and muck conveyance systems, ensuring stable transport.
-
5
Environmentally Friendly, Biodegradable Polymer
Minimizes environmental impact during spoil treatment.
