What is the typical moisture content of the bentonite in Bentomat GCLs?

The moisture content of raw bentonite, before it is incorporated into the GCL, is less than 12%. During manufacturing of the GCL, water is added to the bentonite to assist GCL needle-punching. The resulting bentonite moisture content in Bentomat leaving our manufacturing facilities is between 25 and 40%, with typical values of about 30%. These values are well below that of fully hydrated bentonite, and will have no negative effect on performance. In fact, bentonite with 25 to 40% moisture has the appearance, consistency, and strength of a granular soil.
