Bentonite is becoming increasingly popular in South Africa in its application as an impervious liner either pure or mixed with soil. The local deposits of bentonite are of a quality equal to well-known international products. This paper summarizes the results of a laboratory investigation of selected engineering properties of the South African bentonites, including swell and permeability, and provides a deeper understanding of the chemical and geotechnical properties of bentonite.
