Building a Cavity Wall
This topic introduces learners to the fundamental practical skills and safety requirements for constructing a basic cavity wall. It covers the entire process from preparation and safe mixing of mortar to the actual bricklaying and subsequent clean-up of the work area, emphasising essential health and safety practices at every stage.
Assessment criteria
Topic Overview
The Open Awards Entry Level Award in Skills for Further Learning and Employment (Entry 1) (RQF) is a foundational qualification designed to help you build the essential skills needed for success in further education and the workplace. This award focuses on developing your communication, numeracy, and personal development skills at a basic level, ensuring you can progress confidently to higher-level study or employment. It is part of the Foundations for Learning suite, which provides a stepping stone for learners who may need extra support to achieve their goals.
This qualification covers key areas such as following instructions, working with others, managing your own learning, and applying basic maths and English in practical contexts. You will learn how to set personal targets, complete tasks with support, and reflect on your progress. These skills are crucial for everyday life and form the building blocks for more advanced qualifications, such as Entry Level 2 or 3, and eventually GCSEs or vocational courses.
By studying this award, you will gain confidence in your abilities and develop a positive attitude towards learning. The course is assessed through a portfolio of evidence, meaning you will collect examples of your work to demonstrate your skills. This approach allows you to learn at your own pace and receive feedback to improve. Whether you aim to move into further education, an apprenticeship, or employment, this qualification provides a solid foundation for your future.

Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for correctly donning steel-toe boots, hard hat, hi-vis vest, and gloves before commencing any work
- Expect mortar to be mixed to a stiff but workable consistency, free from lumps or dry pockets
- Look for tidy, even brickwork with joints approximately 10mm thick and bricks laid level and flush
- Check that all tools are washed free of mortar and stored correctly, and the work area is swept clean of debris
- Award credit for demonstrating the correct selection and consistent wearing of appropriate PPE (e.g., hard hat, steel-toe boots, hi-vis vest, gloves) throughout the assessment.
- Award credit for accurately measuring and mixing mortar components (sand, cement, water) to achieve a uniform, workable consistency without evidence of segregation or excessive water.
- Award credit for constructing a stable cavity wall section with consistent bed joints, perp joints, and cavity width, demonstrating appropriate use of wall ties and damp-proof course as instructed.
- Award credit for implementing safe manual handling techniques when lifting and moving bricks and materials, including bending knees and keeping back straight.
- Award credit for effectively cleaning tools and equipment after use, and correctly segregating waste materials into designated containers, leaving the work area free from hazards.
- Check that the learner wears appropriate PPE (hard hat, safety boots, hi-vis, gloves) throughout the task
- Verify that mortar is mixed to an even, workable consistency with no dry pockets or excess water
- Observe that the wall is built plumb, level, and to gauge, with cavity ties correctly positioned
- Confirm all debris is cleared, tools are cleaned and stored, and waste is sorted into correct disposal containers
Assessment Guidance
Guidance for achieving higher grades
- 💡During practical assessment, verbally explain each step of your process to demonstrate your understanding of safety protocols
- 💡Organise all materials and tools before beginning the task to minimise trips and interruptions
- 💡If a mistake occurs during bricklaying, correct it immediately rather than leaving it for later, as this shows proactive quality control
- 💡Practice the mixing sequence: dry mix sand and cement first, then gradually add water while turning, to achieve a consistent plastic mortar without lumps.
- 💡Use a gauge rod or story pole to regularly check bed joint heights and maintain level; this avoids cumulative errors and demonstrates precision to the assessor.
- 💡Verbally narrate your safety checks to the assessor, such as stating you are clearing trip hazards or checking your work area, to evidence your understanding even if you are nervous.
- 💡At the end of the task, systematically clean and store tools, sweep the area, and separate waste into appropriate bins, ensuring you leave a positive final impression for the tidy-up criterion.
- 💡Always carry out a quick visual risk assessment of your work area before starting and mention it to the assessor
- 💡Take time to set out the first course accurately—this dictates the quality of the entire wall
- 💡Show awareness of COSHH by handling cement and mortar with care and explaining the hazards
- 💡Keep a record of everything you do, even small tasks. Your portfolio needs evidence of your progress, so save worksheets, photos of group work, and notes from discussions. This makes it easier to show you've met the criteria.
- 💡When setting targets, make them specific and achievable. For example, 'I will complete my maths worksheet with help' is better than 'I will get better at maths'. This helps you and your tutor track your progress clearly.
- 💡In group activities, make sure you contribute at least once. Even saying 'I agree' or 'Let's try this' shows you are working with others. Your tutor will observe this and note it in your assessment.
Common Mistakes
Common errors to avoid in your coursework
- Neglecting to wear gloves when handling wet mortar, leading to skin irritation from cement
- Adding excessive water to the mortar mix, resulting in a weak and sloppy consistency
- Failing to check for underground services before starting any excavation or ground disturbance
- Leaving mortar to set on tools, making cleaning difficult and damaging the equipment
- Forgetting to wear all required PPE items, especially gloves or eye protection during mortar mixing, which compromises safety.
- Adding too much water at once when mixing mortar, resulting in an overly sloppy mix that cannot support brick weight and leads to weak joints.
- Failing to maintain the required 50mm cavity between the inner and outer leaf, often closing the gap unintentionally with mortar snots or by inaccurate brick positioning.
- Neglecting to bed wall ties fully into mortar or spacing them incorrectly, which reduces structural integrity.
- Not cleaning tools immediately after use, causing mortar to harden and making them difficult to clean later, which may result in lost deposit or failure to meet tidying criteria.
- Confusing mortar ratios, leading to weak or crumbly mortar
- Not checking the wall for level during construction, causing uneven courses
- Forgetting to put on safety goggles when mixing or cutting bricks
- Leaving tools and materials scattered, creating slip and trip hazards
- Misconception: 'I don't need to show my working out in numeracy tasks.' Correction: Even at Entry 1, showing your steps (e.g., counting on fingers or using objects) helps your tutor see your understanding and gives you evidence for your portfolio.
- Misconception: 'Working with others means I have to do everything the group says.' Correction: Working with others involves sharing ideas and listening, but you can also suggest your own ideas. It's about cooperation, not just following.
- Misconception: 'I can't ask for help because it shows I'm not good enough.' Correction: Asking for help is a key skill in this qualification. It shows you are managing your learning and seeking support when needed, which is exactly what the course encourages.
