Specialised Solutions for Slurry Construction
Diaphragm wall and bored pile construction relies on bentonite or polymer slurry to maintain trench stability during excavation. As construction progresses, slurry becomes contaminated with excavated soil and requires treatment to maintain properties and enable reuse. Our slurry treatment systems deliver efficient solids separation and fluid recovery, reducing material costs and environmental impact. Desanding, hydrocyclones and centrifuges restore bentonite or polymer slurry to working specification, cutting fresh-fluid purchases and spoil volumes. Reynolds & Bauhm size each plant to the rig output so excavation continues without interruption.
Traditional sodium or calcium bentonite slurries used in diaphragm wall construction require treatment to remove accumulated solids and maintain viscosity and filtration properties.
Synthetic polymer-based slurries offer enhanced performance in certain ground conditions and require specialised treatment to maintain polymer effectiveness.
Our treatment systems recover up to 90% of slurry for reuse, dramatically reducing material consumption and disposal requirements on construction projects.
Treated water meets discharge requirements while dewatered solids are suitable for disposal or beneficial reuse, minimising environmental footprint.
