Grouted anchors and soil nails: inspection, condition assessment and remediation (C794D)

Grouted anchors and soil nails: inspection, condition assessment and remediation has been written to address industry needs. 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. This 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.

Lift-off testing is covered in detail, outlining the general procedures as well as specialist techniques. Safety procedures for anchor inspection and lift-off testing are clearly explained, together with practical options for safe working such as anchor head restraint and safety cages.

Soil nails and soil-nailed structures are also covered in detail. 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. Soil nail testing techniques are addressed, as well as options for remediation and repair.
