Plugging Wells With Hydrated Bentonite, Part 2:

Hydrated bentonite, on the other hand, is deformable and hence self sealing in such circumstances. However one of the problems with the process is getting the bentonite to the bottom of the hole before it sets up. Simply pouring bentonite granules into the well tends to result in bentonite swelling and bridging soon after it hits the water column.
