CIRIA launches new guidance for Grouted Anchors and Soil Nails

CIRIA is pleased to announce the launch of new guidance Grouted anchors and soil nails: inspection, condition assessment and remediation (C794).

Within construction there is huge amount of information concerning the design and construction of grouted anchors and soil nails, but there is lack of guidance on their inspection, condition assessment or remediation.

This must have CIRIA guide addresses intrusive inspections beneath the anchor head, typically the critical section in respect of corrosion, outlines specialist techniques such as destructive de-stress and describes options for remediation and repair, including techniques for removal of corroded sections of tendon at the anchor head, re-coupling and reinstatement of the anchor.

As well as inspection, condition assessment and remediation of soil nails, soil nail testing techniques are addressed, along with options for remediation and repair. This guide seeks to address these aspects, provide further information on monitoring and monitoring intervals.

Devon Mothersille Managing Director, Single Bore Multiple Anchor Ltd & Geoserve Global Ltd and co-author of CIRIA guide C794 stated “asset owners often consider monitoring of anchors as onerous, but it need not be so, as it can be relatively inexpensive, may be combined with inspections in some cases, and can be highly effective in achieving extended service lives. Grouted anchors that are designed, executed and tested in accordance with the current anchor standards are known to perform satisfactorily. C794 provides an overview for asset owners, together with more specialist information for those involved with the inspection, condition assessment and remediation of grouted anchors, anchored structures and soil-nailed structures.”

John O’Donovan, GDG Principal Engineer and co-author of CIRIA guide C794 commented “asset owners will be aware of their structures and the consequences of underperformance. We hope that C794 will assist their decision making process when planning inspection, monitoring and remediation programmes. In our industry today, there is a plethora of information concerning the design and construction of grouted anchors and soil nails, but very little, if any, guidance on their inspection, condition assessment or remediation.”

CIRIA is pleased to announce the launch of new guidance Grouted anchors and soil nails: inspection, condition assessment and remediation (C794).

A launch webinar will be hosted on 18 November.
