I have a project wherein some 25,000 sq ft of existing shotcrete is to undergo varying degrees replacement, repair and restoration. It is on slopes varying from 1:1 to 1:10 or so. It is approximately 40 years old in most cases. It is in a fairly arid climate (Southern New Mexico) with little rainfall and typically low humidity. The subgrade is non-plastic gravelly sandy material. It was reinforced with wire mesh (looks like 6x6x10x10). I’m interested in any techniques and/or materials that might be applicable
