The method in which San Joaquin Gunite applies shotcrete depends on several variables. Economics is probably the most important factor that is taken into consideration before the application even begins. Economics is also a factor throughout the project, but the other important factors are heavily considered, which are: availability of material and equipment, site access and the expertise and preference of the contractor. The difference between a dry and wet application are the point in which the blend comes into contact with water. A dry application is shotcrete pumped out through the nozzle without the blend of water and the wet application pumps out shotcrete that has been blended with water.
