UndergroundQ I’m looking for information as to the thickness design of shotcrete for ditch slope lining purposes. Can you direct me?
Typically, the thickness is a minimum of 3 inches and slope lining in the 6 to 8 inch range is often installed. The reinforcing is also variable with the lightest sections with no reinforcing or a low dosage of polyfibers or light welded wire fabric and the heavier sections with rebar. Basically, a lot of different designs can be used. We are not aware of any widely used standards.
