    CSkills Awards Level 2 Diploma in Craft Masonry (QCF)

    Topic Overview

    The CSkills Awards Level 2 Diploma in Craft Masonry (QCF) is a vocational qualification designed for learners who wish to become skilled stonemasons. It covers the fundamental techniques of working with natural and artificial stone, including cutting, shaping, and fixing stone for construction projects such as walls, arches, and decorative features. This diploma is part of the QCF framework and is recognised by employers across the UK construction industry, providing a solid foundation for a career in heritage restoration, new build, or monument conservation.

    The qualification is structured around practical skills and underpinning knowledge. You will learn to interpret drawings, set out masonry work, mix mortars, and use hand and power tools safely. Health and safety is a core theme, with emphasis on risk assessment and working at height. The diploma also covers the properties of different stone types, such as limestone, sandstone, and granite, and how to select appropriate materials for specific applications. By the end of the course, you will be able to produce masonry components to industry standards, including quoins, voussoirs, and copings.

    This diploma is essential for anyone aiming to progress to advanced craft masonry or supervisory roles. It aligns with the National Occupational Standards for stonemasonry and provides a pathway to the Level 3 Diploma in Stonemasonry. With the UK's rich architectural heritage, skilled masons are in high demand for conservation projects, making this qualification both practical and future-proof.

    Key Concepts

    Core ideas you must understand for this topic

    • Stone types and properties: Understand the characteristics of limestone, sandstone, granite, and marble, including their durability, workability, and appropriate uses in construction.
    • Setting out and measuring: Master the use of gauge rods, squares, and levels to accurately mark out stone for cutting, ensuring correct dimensions and angles for features like arches and corners.
    • Mortar mixing and application: Know the correct ratios of lime, cement, sand, and water for different stone types, and how to apply mortar for bedding and pointing to achieve strong, weather-resistant joints.
    • Tool use and maintenance: Be proficient with hand tools (chisels, mallets, hammers) and power tools (angle grinders, pneumatic hammers), including sharpening and safe operation.
    • Health and safety: Comply with COSHH regulations for dust and chemicals, use PPE correctly, and follow safe working practices for lifting, working at height, and using machinery.

    Learning Objectives

    What you need to know and understand

    • Describe the procedure for safely removing existing battens, underlay, and slates while preserving the roof structure.
    • Explain the correct method for installing new battens and underlay to achieve adequate weatherproofing.
    • Detail the process of replacing slates/tiles and related components, including fixings and flashings.
    • Demonstrate knowledge of removing and replacing rainwater goods to maintain proper drainage.

    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Award credit for stating the correct sequence of operations when stripping a slate/tile roof.
    • Award credit for identifying appropriate materials and fixings required for re-covering.
    • Award credit for explaining how to ensure underlay is lapped correctly to shed water.
    • Award credit for describing safe handling and disposal of removed debris.

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Always reference current building regulations and manufacturers’ installation guidelines in your answers.
    • 💡Use correct terminology for roof components and tools to demonstrate professional competence.
    • 💡Emphasise health and safety considerations, especially working at height and manual handling.
    • 💡Always show your working out in calculations for material quantities and setting out. Even if the final answer is wrong, you can gain marks for correct method and steps.
    • 💡In practical assessments, focus on accuracy of cuts and joints. Examiners look for tight, uniform joints (typically 3-5mm) and clean, straight edges. Take your time to measure twice and cut once.
    • 💡Know your health and safety procedures thoroughly. Questions on risk assessments, COSHH data sheets, and correct PPE use are common and can earn easy marks if you recall specific details like the type of dust mask required for silica dust.

    Common Mistakes

    Common errors to avoid in your coursework

    • Confusing the order of laying underlay and battens, leading to potential water ingress.
    • Using the wrong size or type of nails for slates/tiles, compromising wind uplift resistance.
    • Overlooking the need to inspect and replace damaged sarking or rafters before re-covering.
    • Failing to seal penetrations and junctions adequately when replacing flashings.
    • Misconception: All stone is the same and can be cut with any tool. Correction: Different stones have varying hardness and grain structure. For example, granite requires diamond-tipped tools, while limestone can be shaped with tungsten carbide chisels. Using the wrong tool can damage the stone or cause injury.
    • Misconception: Mortar for stonework is the same as for brickwork. Correction: Stone mortar often uses lime instead of cement to allow for movement and breathability. Cement-based mortar can trap moisture, leading to stone decay in historic buildings.
    • Misconception: You can skip setting out if you have a template. Correction: Templates are only as accurate as the setting out. You must still check dimensions, squareness, and levels to ensure the final assembly fits correctly, especially for complex features like arches.
