Bentonite Sodium Civil Engineering Grade
Sodium bentonite is a civil engineering grade mined and processed in Queensland Australia and available from Permathene Australia. It contains a high percentage of the active mineral montmorillonite, which has a unique structure and chemistry.
Sodium bentonite is manufactured to rigorous standards to ensure consistency. It is manufactured to ISO9001:2008.
Applications include: root barrier as a growth inhibitor, drilling fluids, grouting for tunneling applications, low permeability slurry mixes, ground stabilization, dam sealing and waste containment.
