Thin Spray-on Liners (TSLs) have been used at a variety of South African mines for ground support reasons to a limited extent. The use and application of TSLs are expected to increase once the end-user (the mines) confidence is built on the TSL performance. This would be achieved if there is data available for meaningful comparison between TSL mechanical properties to its nearest counterpart, in this case shotcrete. This paper provides the details of tensile strength testing done on TSLs and shotcrete from sample preparation to test execution and summarizes the test results. The comparison of test results shows that TSLs, in spite of their significantly smaller application thickness, match and in most cases exceed the tensile strength of shotcrete. It is hoped that the comparison made in this paper would provide additional encouragement for the mines to initiate the application of TSLs.
