Grouted anchors and soil nails (C794)

Join us for this webinar launching CIRIA’s new good practice guide ‘Grouted anchors and soil nails: inspection, condition assessment and remediation (C794)’.

Registration has now closed.


There is a wealth of information on the design and construction of grouted anchors, but little or no guidance on their inspection, condition assessment or remediation. In response to industry demand, CIRIA has produced this guidance which covers intrusive inspections beneath the anchor head which is susceptible to corrosion; outlines specialist techniques such as destructive destress; and outlines options for remediation and repair.

Soil nails and soil-nailed structures are also covered in detail in the guide. The approach for inspection, condition assessment and remediation of soil nails, is based on a collective approach, where the soil nails are addressed as part of the soil nailed structure, along with the facing and the drainage.
