Bentonite is a clay that expands when mixed with water. When wet its volume increases by about 13 times compared to its volume when dry. This quality allows it to tightly fill small and irregular spaces between the casing and the hole wall. When mixed with cement the bentonite-cement-slurry creates a seal that is somewhat plastic so that it can ...
