Normet’s TamCrete SSL (structural support liner) was introduced one and a half years ago and is a reactive resin-based, rapid-curing, gas and watertight spray-applied shell. It is applied to a thickness of 5–10 mm and gains 70 to 80% of its peak strength within three to five minutes. This paper gives an overview on application methods, key mechanical properties and case studies. The major focus of the paper will be on field tests that have been executed at a hard rock site in Finland.
