    Lantra Awards Level 2 Award in Dry Stone Walling

    Topic Overview

    Dry stone walling is a traditional craft that involves constructing walls without the use of mortar, relying instead on the careful selection and placement of stones to create a stable, durable structure. This Level 2 Award covers the fundamental principles and practical skills needed to build, repair, and maintain dry stone walls, which are a characteristic feature of the UK landscape, particularly in upland and rural areas. The qualification is designed for learners who have some basic experience or are starting their journey in this heritage skill, and it provides a solid foundation for further study or employment in conservation, landscaping, or countryside management.

    Understanding dry stone walling is important not only for preserving cultural heritage but also for supporting biodiversity and sustainable land management. Dry stone walls provide habitats for a range of plants and animals, act as boundaries, and help manage livestock. The course covers key aspects such as health and safety, stone selection, wall construction techniques (including batter, throughstones, and coping), and basic repair methods. By mastering these skills, students contribute to the maintenance of an iconic element of the British countryside while gaining a practical, hands-on qualification that is valued by employers in the environmental and construction sectors.

    Key Concepts

    Core ideas you must understand for this topic

    • →Batter: The slight inward slope of a dry stone wall from base to top, which improves stability by shifting the centre of gravity inward. Typically, the batter is about 1 inch per foot of height.
    • →Throughstones: Long stones placed across the width of the wall to tie the two faces together, preventing bulging or collapse. They should be evenly spaced and extend through both faces.
    • →Coping: The top layer of stones, often placed vertically or at an angle, to finish the wall and protect it from weather. Common styles include cock-and-hen, flat coping, and ridge coping.
    • →Hearting: The small stones and chips used to fill the core of the wall, providing internal stability and drainage. Proper hearting prevents voids that could lead to settlement.
    • →Stone selection and dressing: Choosing stones of suitable size, shape, and type for different parts of the wall, and using a hammer to trim or shape stones for a better fit without splitting them unnecessarily.

    Learning Objectives

    What you need to know and understand

    • 1. Be able to prepare the area ready to strip out a dry stone wall2. Strip out a dry stone wall in preparation for building, laying stones out according to their use

    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Award credit for correctly identifying and wearing appropriate personal protective equipment (PPE) throughout the stripping process.
    • Award credit for establishing a safe working area with clear exclusion zones and stable stacking platforms.
    • Award credit for systematically removing stones in reverse order of construction, preserving throughs and copes intact.

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Before starting, assess the wall's condition to anticipate unstable sections and plan your systematic strip-out.
    • 💡Lay stones on level ground, grouped by type and size, with throughs marked clearly to facilitate efficient rebuilding.
    • 💡Pay close attention to the batter: use a batter frame or spirit level regularly to check the slope. Examiners look for consistent batter throughout the wall, as this is critical for stability.
    • 💡Demonstrate safe working practices at all times, including correct lifting techniques, use of personal protective equipment (PPE), and tool handling. Marks are often awarded for safety awareness as well as technical skill.
    • 💡When repairing a wall, always assess the cause of failure first (e.g., missing throughstones, poor foundation). A common mistake is to rebuild without addressing the underlying issue, which leads to repeated collapse.

    Common Mistakes

    Common errors to avoid in your coursework

    • Failing to segregate hearting from face stones, leading to inefficient rebuilding and poor wall structure.
    • Dropping or throwing stones during stripping, causing unnecessary damage and potential injury.
    • Underestimating the weight of stones and attempting to lift or carry them without proper manual handling techniques.
    • Misconception: Dry stone walls are simply stacked stones with no engineering. Correction: Successful walls rely on precise principles of gravity, friction, and interlocking. Each stone must be carefully placed to distribute load and resist lateral forces, much like a jigsaw puzzle.
    • Misconception: Any stone can be used anywhere in the wall. Correction: Stones must be selected for their role—large, flat stones for the base and throughstones, smaller ones for hearting, and specific shapes for coping. Using the wrong stone in the wrong place compromises strength.
    • Misconception: Mortar makes a wall stronger, so dry stone walls are inferior. Correction: Dry stone walls are designed to be flexible and allow water drainage, which reduces frost damage. Mortared walls can trap water and crack, whereas dry stone walls can settle and move without failing.
