The need for a UK-focused reference for grouting in dams and their adjoining structures is to be addressed with the publication new guidance by Ciria later this month.
The C774 Grouting for reservoir dams - a guide to good practice provides comprehensive, good practice guidance covering grouting in UK dams including investigation, design, grouting materials and processes, drilling and grouting plant, quality control and verification.
Development of the new guidance was led by Atkins and the key authors were Dams and Reservoirs managing director Andy Hughes, Atkins technical manager Tony Bruggemann, independent consultant Clif Kettle and Soletanche Bachy deputy laboratory manager Christophe Justino.
The guidance can be used to investigate and evaluate the need for grouting on both new and existing dams and covers defects that can be remediated through grouting, as well as grouting design, injection methods, mix design and equipment. The guidance also looks at quality control and environmental issues and contracts used for this type of work.
Case studies are a key feature of the new document, which is aimed at reservoir owners and reservoir safety engineers concerned with the design of new dams and inspection and remediation of existing structures.
According to Ciria, the guidance is also expected to be of value to new engineers entering the profession and looking to learn about grouting practices, as well as anyone undertaking procurement, environmental protection or contractual matters relating to dam grouting work.
