About the topic:
Concrete is the most versatile building material in the construction industry. There are many types of concrete technologies that continually increase the versatility of this widely used building material. One process that has been around for over 100 years is a method of placing concrete called “Shotcrete”. Shotcrete is a term used to describe pneumatically spraying concrete.
In BC, shotcrete has commonly been used in shoring walls and soil stabilization but there is a growing trend to use shotcrete in structural applications and building facades and foundations. Although the end result is very similar (and in many cases superior) to that of cast in place concrete, there are many different considerations to take into account when waterproofing a shotcrete wall versus a cast in place wall. Not all cast in place waterproofing systems and details are as effective in shotcrete applications as they are in cast in place (especially if the shotcrete methodology is not understood by the specifier). Alterations to details should be made in some cases to ensure the differences between shotcrete and cast in place are taken into account.
This presentation will cover a basic introduction to the shotcrete process including benefits of shotcrete, procedures, how it is different, things to note when specifying details for it and some local projects. The presentation will also cover Kryton details for shotcrete and in what ways they differ from the cast in place details as well as the benefits of using Kryton’s KIM with shotcrete over membrane systems.
