The sodium bentonite should be rotary hoed into the soil at a depth of 10-15 cm to achieve as accurate a mixture as possible. Merely having the sodium bentonite incorporated at an overall average rate will lead to less than expected performance - the relatively undertreated areas will be weak spots that will allow high percolation rates.

Bentonite can also be used to repair existing dams, but it is important to identify where the leak occurs. Repair methods include the application of granular Bentonite on top of the water surface, the manual addition of a soil/Bentonite mix to erosion holes, or the construction of cut off trenches. Bentonite can also be used with cement to ...


Bentonite panel system: note nailing and poor seams Comments: Bentonite panels are difficult to install correctly, often the Bentonite is segregated within the panel leaving undetected voids that allow leakage. The attachment to the concrete requires nailing, which must be surfaced sealed. The surface sealing is often poorly done allowing leakage.


Properties of Flowable Fill Concrete. It has high lump (nearly 9 inch) but the strength is low, commonly 100 PSI (0.7 Mpa) in 28 days. It has low cementitious mix, does not hydrate and it settles and dewaters. The less water does not equate to faster hardening and too little water will not allow proper settlement.
