Production and Quality Assurance


During the process of manufacturing Bentomat, samples are taken at regular intervals.  In our Research & Development center, products undergo comprehensive quality assurance testing including:
  • Permeability/index flux
  • Slope stability determination by direct shear box method
  • Montmorillonite content by x-ray diffraction
  • Cation exchange capacity by methylene blue or wet chemistry
  • Mass per unit area
  • Tensile strength
  • Peel strength
  • Elongation
  • CBR puncture resistance
  • Filtrate loss
  • Free swell
  • Plate water absorption
  • Chemical compatibility

Once all the required tests have been carried out and have met the appropriate criteria, the product is approved for dispatch.


We have production facilities in several countries to better serve our global markets.
