The SwellSeal® MS Bentonite System must:

  • be used adequately confined and protected against damage during construction and in service; and,
  • not be used where ground water conductivity exceeds 2,500 µS/cm-1 except on advice from SwellSeal Waterproofing New Zealand Limited (Refer Paragraph 11.1).

All installations incorporating the SwellSeal® MS Bentonite System must be the subject of specific design.
