Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating correct preparation of sub-base, ensuring appropriate levels, falls, and thorough compaction to prevent future settlement.
- Award credit for accurately mixing sand and cement mortar by hand and mechanical methods, achieving consistent workability and correct proportions as per specification.
- Award credit for laying modular paving with consistent joint widths, correct alignment, and surface falls, and for compacting and finishing to industry standards.
- Award credit for safe and efficient use of tools and equipment throughout the process, including protective measures for finished work.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always verify ground conditions and sub-base specifications before starting; document checks for evidence.
- 💡Practice both hand and mechanical mixing techniques to demonstrate competence; record the mix proportions used.
- 💡Inspect paving after each stage—after laying, after initial compaction, and after jointing—and correct any defects before final assessment.
- 💡Always use correct technical terms in your answers, such as 'aggregate' instead of 'stones'.
- 💡Show all your working in calculations, even if you make a mistake, you can gain method marks.
- 💡Read questions carefully and underline key words like 'calculate', 'state', or 'describe' to know what is expected.
Common Mistakes
Common errors to avoid in your coursework
- Failing to adequately compact the sub-base in layers, leading to uneven settlement and paving failure.
- Using incorrect sand-to-cement ratios or adding too much water, resulting in weak or unworkable mortar.
- Neglecting to use string lines or levels during laying, causing poor alignment, lipping, or incorrect drainage falls.
- Misconception: 'Health and safety is just common sense.' Correction: It is a legal requirement based on risk assessments and regulations like the Health and Safety at Work Act 1974.
- Misconception: 'All bricks are the same size.' Correction: Standard UK brick size is 215mm × 102.5mm × 65mm, but specials and different types exist.
- Misconception: 'Concrete and cement are the same.' Correction: Cement is a component of concrete; concrete also includes sand, aggregate, and water.
Revision Plan
How to revise this topic in 1–2 weeks

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A construction site requires a concrete mix with a ratio of 1:2:4 (cement:sand:aggregate). If you need 1.4 m³ of concrete, how many cubic metres of sand are needed?
- 1.Step 1: Identify the total parts in the ratio: 1+2+4 = 7 parts.
- 2.Step 2: Calculate the volume of one part: 1.4 m³ ÷ 7 = 0.2 m³.
- 3.Step 3: Multiply by the number of parts for sand (2): 0.2 m³ × 2 = 0.4 m³.
Question: A brick wall is 6 metres long and 1.5 metres high. If each brick measures 215mm × 65mm and you ignore mortar, estimate the number of bricks needed.
- 1.Step 1: Convert wall dimensions to millimetres: 6m = 6000mm, 1.5m = 1500mm.
- 2.Step 2: Calculate wall area: 6000mm × 1500mm = 9,000,000 mm².
- 3.Step 3: Calculate brick area: 215mm × 65mm = 13,975 mm².
- 4.Step 4: Divide wall area by brick area: 9,000,000 ÷ 13,975 ≈ 644 bricks.
