    Once EZ-SEAL® bentonite is added to the mixing water, the slurry will have an “oatmeal consistency” containing un-yielded and partially hydrated bentonite granules. It is recommended the product be blended only long enough to gain suspension of the EZ-SEAL® material. Immediately tremie the grout into place to allow the bentonite granules to hydrate and swell in situ. Do not over mix and do not use a centrifugal pump.

    It is recommended that Soda Ash (sodium carbonate) be added to the make-up water prior to the addition of EZ-SEAL® granular bentonite for reduction of excess calcium and pH adjustment.
