Tradition

The building of dry stone walls is a long- standing rural-farming tradition dating back to the Neolithic Period here (5,000 years ago). There was also a time professional dry stone wallers travelled through the country, as well as over and back from Ireland to England, and Wales. Many walls on estates and larger farms were built by these skilled craft workers as far back as the medieval period. The longest continuous length of dry stone wall in Britain and Ireland, The Mourne Wall (35km) in Co. Down is a good example of this. Common stones used in Ireland include Section of Famine Wall at Salt Hill Pier in Co. Donegal. The wall and pier were built as poverty relief work in , and . 1846, but the wall fell into disrepair.

The basic In general, stonemasons and dry stone principles of bonding, pinning, hearting wallers need to know about different types and use of batter ensure that dry stone of stone, rough cutting and shaping out, walling is a flexible way of building with building techniques and principles, stone that transcends all stone types. measurement and safe work practices. Wallers can build with field stone or stone. Types of stone wall

Fixing old walls

Repairs to old dry stone walls should be done using the same stone. If a wall has collapsed in sections it should be fixed without the use of cement. Introducing to a section of dry stone wall can have the effect of destabilising the wall either side of it, and rapid collapse of previously intact sections of wall can occur due to decreased flexibility and pressure transferred by the now rigid mortared section. Consequently, an entire stretch of dry stone wall can end up being replaced by a mortared wall, which is neither appropriate nor environmentally friendly. A cemented wall can hold moisture in the stone, leading to rapid decay of the stone. Wall in need of repair. Photo courtesy of the DSWAI.
