- A specially selected soda exchanged bentonite for Slurry Cut-Off Wall applications, used in conjunction with OPC / GGBS or PFA formulations to produce a solid impermeable barrier wall. Equally suited to demanding Diaphragm wall applications.
- KM SW disperses rapidly in water to form a mud with good viscosity and gel strength that is very stable and which can be used within 2 mins of mixing although rheology improves further if left to hydrate longer.
- If quick mixing with no pre-hydration of the bentonite, it is recommended to mix the bentonite in water first and shear for at least 2 minutes before adding the GGBS and then the OPC.
- Bleed on finished set slurry always <2% and typically <1% after 24 hrs.
