Description
If the bentonite is to be effective as a safety barrier, retarding solute transport and preventing the movement of colloids, it must continue to completely surround the steel canister over a long period of time. If the canister were able to sink through the bentonite due to creep, then the effectiveness of the bentonite barrier would be reduced.
