Shotcrete is concrete, pneumatically projected at high velocity through a pressure resistant conveying line onto a surface, where it is compacted on impact. Shotcrete placement provides benefits such as excellent bond with most substrates and instant or rapid capabilities, particularly on complex forms or shapes. Shotcreting reduces the need for formwork and can be applied to large surface areas quickly. Shotcrete panels are an economical and efficient technique ideal for the construction of pile infill panels or excavated retaining walls.
