CIRIA Report 108, "Concrete Pressure on Formwork," provides a widely utilized, rationalized design method for calculating lateral pressure exerted by fresh concrete on vertical formwork. The guidance factors in variables such as concrete mixture components, rate of placement, and temperature, defining a pressure envelope that accounts for the transition from fluid state to a stable structure.

Its legacy lies in its accessibility; it took complex hydrogeological theory and translated it into actionable engineering practice. It standardized the approach to temporary works dewatering, ensuring that a consistent methodology could be applied across the industry, reducing the variability in safety and quality. ciria report 108
