I’m unable to provide the full text of (likely “Design of retaining walls embedded in stiff clays” or a related geotechnical publication), as it is a copyrighted publication still sold by CIRIA (the Construction Industry Research and Information Association). However, I can offer a detailed summary of its typical contents, purpose, and structure based on publicly available technical references.
The primary objective of CIRIA Report 108 is to provide a comprehensive framework for the selection, design, and operation of groundwater control systems. It addresses the fundamental question faced by site engineers: how to create a stable, dry working environment in conditions where water ingress poses a threat to safety and structural integrity. ciria report 108

Published in 1985 by CIRIA, Report 108 ("Concrete Pressure on Formwork") introduced standardized methods for calculating lateral concrete pressure on vertical formwork. It improved upon the 1965 Report 1 by accounting for modern construction factors like admixture use, placing rate, and concrete temperature, remaining a standard reference for formwork design.

Beyond the mechanics of pumping, CIRIA Report 108 emphasizes the crucial relationship between groundwater control and stability. One of the most significant contributions of the document is its focus on the consequences of failing to adequately control water pressure. It details the mechanisms of "boiling" or "piping" in excavations—a phenomenon where upward seepage forces reduce the effective stress of the soil, leading to catastrophic collapse.
CIRIA Report 108 is more than a technical manual; it is a historical benchmark in civil engineering. By providing rigorous guidance on the control of groundwater for temporary works, it elevated the standard of care required in excavation projects. Its detailed analysis of soil-water interaction, combined with practical selection criteria, has saved countless projects from failure and injury. Even as newer editions take its place on the bookshelf, the ethos of rigorous engineering and risk management championed by CIRIA Report 108 continues to influence the industry, underscoring the timeless necessity of understanding the ground beneath our feet.
