    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 of dry stone walling, including understanding the different types of stone, the tools and equipment required, and the techniques for building a wall that is both functional and aesthetically pleasing. The course also emphasises health and safety considerations, environmental impact, and the historical and cultural significance of dry stone walls in the UK landscape.

    Mastering dry stone walling is important not only for preserving rural heritage but also for developing practical skills that are in demand for conservation projects, landscaping, and agricultural management. Dry stone walls provide essential habitats for wildlife, manage livestock, and define boundaries, making them a key feature of sustainable land management. This qualification equips students with the knowledge and hands-on ability to construct and repair walls to industry standards, contributing to the maintenance of the UK's iconic countryside.

    Within the broader context of environmental science, dry stone walling exemplifies how traditional practices can support biodiversity, soil conservation, and sustainable land use. The course integrates principles of geology, ecology, and construction, showing how human intervention can positively shape landscapes. By learning this craft, students gain a deeper appreciation for the interplay between human activity and natural systems, and develop transferable skills in problem-solving, manual dexterity, and attention to detail.

    Key Concepts

    Core ideas you must understand for this topic

    • →Stone selection and classification: understanding the properties of different stone types (e.g., limestone, sandstone, granite) and how they affect wall stability and appearance.
    • →Wall construction techniques: including the use of throughstones, hearting, and coping stones to create a strong, free-draining structure that can withstand weather and livestock pressure.
    • →Health and safety: correct manual handling techniques, use of personal protective equipment (PPE), and risk assessment for working with heavy materials and tools.
    • →Environmental and ecological considerations: how dry stone walls provide habitats for plants and animals, and the importance of maintaining gaps for wildlife passage.
    • →Tools and equipment: proper use and maintenance of hammers, chisels, levels, and string lines to achieve accurate alignment and batter (the slight inward slope of the wall face).

    Learning Objectives

    What you need to know and understand

    • 1. Understand mortarless masonry 2. Know the characteristics of different types of stones 3. Know the functions of different types of stones4. Know where to source different types of stones used to build a dry stone wall

    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Demonstrate knowledge of at least three stone types and their key characteristics (e.g., sandstone, limestone, granite).
    • Explain the function of through stones and how they tie the wall together.
    • Identify suitable sources for local stone, considering sustainability and traditions.

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Use clear labeling when presenting stone samples or images in evidence.
    • 💡Relate stone type choice to a specific wall project, discussing local availability and cost.
    • 💡Prepare to answer questions on sourcing, including quarries, reclaimed stone, and legal considerations.
    • 💡Pay close attention to the batter of the wall. Use a batter frame or level regularly to ensure the wall tapers inward correctly from base to top – this is a common area where marks are lost.
    • 💡Demonstrate your understanding of stone selection by explaining why you choose particular stones for throughstones, hearting, and coping. Examiners look for evidence of thoughtful decision-making.
    • 💡Always mention health and safety in your answers, especially when describing techniques. Show that you can identify hazards and explain how to mitigate them, such as proper lifting techniques and wearing gloves.

    Common Mistakes

    Common errors to avoid in your coursework

    • Confusing stone types with similar appearances, such as gritstone and sandstone.
    • Assuming all stones are equally suitable for all parts of the wall, ignoring durability for coping.
    • Overlooking the importance of bedding planes and laying stones correctly.
    • Misconception: Dry stone walls are simply piles of rocks. Correction: A well-built dry stone wall is carefully engineered with interlocking stones, a proper foundation, and a consistent batter to ensure stability and longevity.
    • Misconception: Any type of stone can be used interchangeably. Correction: Different stones have varying shapes, sizes, and weathering characteristics; selecting the right stone for each part of the wall (e.g., throughstones for tying the wall together) is critical.
    • Misconception: Mortar makes a wall stronger. Correction: Dry stone walls are designed to be flexible and allow water drainage; mortar can trap moisture, leading to frost damage and structural failure.
