METHOD OF BENTONITE APPLICATION

摘要

METHOD OF BENTONITE APPLICATION A method of sealing a sub-surface wall with a homogeneous gel of bentonite in water. The gel is prepared by placing an aqueous suspension of less than six percent by weight of bentonite in a vessel, recirculating the suspension and adding bentonite to a final concentration of between six and twenty percent by weight. The gel so produced is applied to the wall surface by spraying, forming a stable, nonflowing gel coating thereon.
