Where to find the material and what it actually covers
If you are looking for A Guide To Dry Stone Walling Andy Radford, it is a printed book available through specialist masonry suppliers, some UK book retailers, and occasionally second-hand marketplaces. It is not a free PDF you will stumble across on a random forum. The content itself is straightforward: Radford breaks down the construction of dry stone walls from the foundation up, covering tool selection, stone types, wall profiles, drainage considerations, and repair techniques. It is aimed at beginners to intermediate builders who want a systematic approach rather than learning purely through apprenticeship. The book leans heavily on the British tradition of dry stone walling, which means you will see terminology like batter, through stones, pinner stones, face stones, and core fill used without extensive glossary backing. If you already know these terms the text flows well. If you do not, you may need to pause and look things up as you go.
A Guide To Dry Stone Walling Andy Radford — what the practical sections get right
The section on foundation preparation is where this guide separates itself from most beginner resources. Most people skip foundation work because they assume a dry stone wall just sits on the ground. It does not. Radford explains how to excavate to firm subsoil, lay a broad base course, and compact it properly before building up. I learned this the hard way on a garden wall I built in 2019 using a different set of notes that skipped the excavation step. Within two winters the lower third had shifted about forty millimetres and developed a visible lean. The fix involved dismantling the bottom two courses and redoing the base with proper gravel compaction. His coverage of batter measurement is also useful. The standard batter for a boundary wall is roughly one in six — meaning for every six units of height, the wall sets back one unit from the vertical. Radford shows how to check this with a simple plumb line and spirit level combination, and he includes notes on how steeper batters are needed for retaining walls where lateral soil pressure is involved. The diagrams are functional rather than artistic, which is fine because they get the point across without distracting you.
The parts that need context
No single guide covers every terrain or stone type you will encounter, and this one is no exception. Radford writes from a perspective shaped by the upland and pastoral regions of Britain, where limestone, sandstone, and granite are commonly available. If you are working in an area where the local stone is soft and crumbly or unusually sharp-edged and fragmented, some of his advice on selection and dressing needs adaptation. One specific edge case I ran into: I was rebuilding a low field wall in an area dominated by flint nodules. Flint is tough, irregular, and does not plane or dress easily. Radford's guidance on creating a level building surface assumes you can select and orient stones to form a relatively flat bed joint by choosing the right pieces. With flint, that approach breaks down quickly. My workaround was to use a narrower range of smaller flint pieces for the bedding layer and rely more heavily on smaller spalls and chippings for leveling, rather than trying to find perfect natural faces. It slowed construction but produced a stable result. The guide does not address this scenario directly, so you will need to adjust on the fly.

Counter-intuitive points worth remembering
Here are a couple of things the guide gets right that beginners consistently misunderstand. Distribution of through stones is more important than quantity. Many new builders think tossing in a few long through stones every metre or so is sufficient. The real principle is that through stones should be distributed evenly along the length and at regular vertical intervals, tying the two faces together. A wall with twenty through stones clustered in one section and none elsewhere will perform worse than a wall with fewer through stones that are evenly spaced. Radford covers this but the implication is easy to miss if you skim. The core is not waste material. There is a persistent myth that the inner fill of a dry stone wall can be any rubble you dig up. It cannot. Core fill needs to be reasonably angular and appropriately sized — small enough to lock between the face stones but large enough to create interlock. Rounded river stones or soil-based rubble will settle over time and create voids that compromise stability. Radford mentions this briefly in the materials section, but it deserves more emphasis than it gets.
Limitations and what the book does not handle
The guide does not cover mechanised stone handling, large-scale agricultural wall construction, or modern engineering assessments of existing walls. If you are dealing with a listed or scheduled ancient wall where conservation standards apply, you will need additional references on heritage masonry practices. Radford's work is practical and hands-on, not archival or regulatory. It also does not include extensive photography. The illustrations are line drawings and schematics. If you learn better from photographic reference of real wall sections, cross-sections, and detail shots, you should supplement this with visual materials from the Dry Stone Walling Association or regional heritage trusts.
How I use it alongside other references
I keep a copy on site when I am teaching or consulting. The chapter on wall repairs is the section I return to most often, particularly the guidance on localised failure remediation — stabilising a bulge without completely rebuilding. That technique alone saved me from a full reconstruction on a section of wall that had been pushed outward by a fallen branch over several years. The repair involved removing the displaced face stones, resetting them with proper batter, inserting new through stones, and repacking the core with fresh angular fill. The guide walked me through the sequence in about three pages. For sourcing the book itself, check specialist building and heritage suppliers first. Online second-hand dealers sometimes list copies at reasonable prices since it is not a mass-market title. If you find a used copy, check that the binding is intact and the pages are not water-damaged — the diagrams need to be readable while you are actually building. The guide is competent, grounded, and not overly romanticised about the craft. It reads like someone who has actually built walls rather than someone who has written about them from a distance. That distinction matters when you are standing in a field with a bag of stones and a mallet, trying to figure out why the course you just laid keeps rocking under your weight.
