Depending on the site conditions, Bentomat is available in different configurations to best suit your needs. When high internal shear strength is necessary, Bentomat offers maximum performance. This product is available in a woven/nonwoven configuration as well as a double nonwoven version. The double nonwoven edition of the product provides the highest interface friction values when necessary. Bentomat meets hydraulic performance requirements with a permability of 5 x 10-9 centimeters per second, approximately 20 times lower than a typical GCL.
