Wall-to-wall improvements
A new CIRIA project Dry stone retaining walls: condition appraisal and remedial treatment (RP723) will build on CIRIA's successful asset management themed reports.
Dry stone walls have been used as retaining structures in the UK for many hundreds of years; most of which were erected in the 18th and 19th centuries and still remain in use today There is an estimated 9,000km of dry stone wall providing structural support to the UK road network alone (TRL survey)

Comprehensive publication describes chalk's geological setting, its origins, occurrence, its stratigraphy, weathering and geomorphological situations, the materials and mechanical properties.
Although the majority may be deemed generally in good condition with considerable residual lifetime, an increasing number of collapses has highlighted difficulties in maintaining them.
The inherent flexibility of these walls can often mask impending failure or severe distress.
To ensure that dry stone retaining walls continue to meet acceptable standards of durability, stability and performance set by asset owners and regulatory bodies, there needs to be a standard method of assessment for dry stone retaining walls that can be universally used by the highways authorities.
A new CIRIA project Dry stone retaining walls: condition appraisal and remedial treatment (RP723) will build on CIRIA's successful asset management themed reports on infrastructure embankments and cuttings and the forthcoming guidance on masonry and brick arch bridges, and tunnels to provide infrastructure owners, their consultants, contractors and maintenance contractors and inspectors with comprehensive best practice guidance on all aspects of the condition appraisal, monitoring, repair and maintenance of dry stone retaining walls.
The report will lead to cost savings through a better appreciation of how these structures work, avoiding inappropriate repairs and unnecessary replacement.
This CIRIA project is being supported by major infrastructure interest groups and asset owners including the Department for Transport, County Surveyors Society, Northern Ireland Roads Service, Network Rail and British Waterways.
