    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 emphasises both safety and environmental stewardship.

    Understanding dry stone walling is important not only for preserving cultural heritage but also for supporting biodiversity and land management. Dry stone walls provide habitats for wildlife, act as boundaries, and help manage livestock. This course fits within the broader context of environmental science and land-based studies, linking to topics such as habitat conservation, sustainable land use, and traditional rural crafts. By mastering these techniques, students contribute to the maintenance of a sustainable landscape and gain a skill that is increasingly valued in conservation and countryside management.

    Key Concepts

    Core ideas you must understand for this topic

    • →Stone selection and grading: choosing the right type and size of stone for different parts of the wall, including foundation stones, fillers, and capstones.
    • →Wall construction techniques: building a stable structure using the 'through stone' method, ensuring correct batter (slope) and alignment.
    • →Health and safety: using personal protective equipment (PPE), manual handling techniques, and working safely with tools such as hammers and chisels.
    • →Environmental considerations: understanding the impact of walling on local ecosystems, including providing habitats for flora and fauna.
    • →Repair and maintenance: identifying common defects like bulging, leaning, or missing stones, and applying appropriate repair methods.

    Learning Objectives

    What you need to know and understand

    • 1. Be able to build and pack a dry stone wall

    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Award credit for demonstrating correct stone orientation, ensuring the length of each stone runs into the wall to promote interlock.
    • Award credit for achieving a consistent batter (typically 1:6 for a field wall) with faces rising evenly on both sides.
    • Award credit for thorough packing of hearting (small stones) to fill all internal voids, providing structural integrity.
    • Award credit for placing through-stones at regular intervals (approximately every metre horizontally and every other course vertically) to tie the wall faces together.
    • Award credit for maintaining level courses with good face alignment, avoiding running joints and using a string line as a guide.

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Regularly step back from the wall to visually check the batter, face alignment, and coursing; use a spirit level and string line frequently.
    • 💡Dedicate time to meticulous hearting after each course; assessors often award higher marks for dense packing that eliminates movement.
    • 💡Practice safe stone handling, including correct lifting posture and use of protective gear, as health and safety observations are integral to assessment.
    • 💡Plan stone selection for each section, keeping a mix of shapes and sizes to hand, and demonstrate an efficient workflow that minimises waste and effort.
    • 💡Focus on the sequence of construction: examiners look for a logical approach, from preparing the foundation to placing the capstones. Demonstrate that you understand the importance of each step.
    • 💡Pay attention to the batter (the inward slope of the wall). A consistent batter on both sides is crucial for stability. Practise measuring and checking this with a spirit level or batter frame.
    • 💡Use correct terminology in your answers, such as 'hearting' (the small stones filling the core) and 'through stones' (long stones spanning the width). This shows depth of knowledge.

    Common Mistakes

    Common errors to avoid in your coursework

    • Placing stones with their natural bedding planes vertical rather than horizontal, which can lead to splitting under load or frost action.
    • Neglecting proper hearting, resulting in a wall that is loose and unstable due to internal gaps.
    • Failing to tie the two faces with through-stones or using them too infrequently, leading to bulging or collapse.
    • Building on poorly prepared foundations without removing topsoil or setting a firm base of larger stones, causing uneven settlement.
    • Misconception: Dry stone walls are simply piles of rocks. Correction: They are carefully engineered structures with a specific construction sequence, including a foundation, hearting, and coping stones, designed to withstand weather and livestock pressure.
    • Misconception: Any stone can be used anywhere in the wall. Correction: Stones must be selected for their shape, size, and strength; for example, flat stones are best for the base, while long stones are used as through stones to tie the wall together.
    • Misconception: Mortar makes a wall stronger. Correction: Dry stone walls are flexible and allow water to drain through, reducing frost damage. Mortar can trap moisture and cause structural failure.
