Overview

This standard is for those who install small-element kerbs and edge restraints that are used within the hard-landscaping industries.

It is suitable for operatives working under limited supervision and focuses on the skills required both to understand the structure and undertake the installation of edge restraints while working to specifications.

You will be expected to understand the impact of the installation work on the immediate environment, and the impact of the environment on the structure.

  4. place and prepare a suitable bed for installing small-element kerbs and edge restraints
  5. lay units to the correct line and level
  6. cut in units to required specifications
  7. maintain correct joint width
  8. check completed installation of small-element kerbs and edge restraints for compliance and rectify any problems
  9. haunch units

  3. how to measure to ensure work is within tolerances
  4. how falls, lines and levels are determined and set out
  5. how to select, prepare and use the correct tools and equipment for installation of small-element kerbs and edge restraints, including personal protective equipment (PPE) and respiratory protective equipment (RPE)
  6. how to maintain, clean and store the required tools and equipment correctly
  7. the range of small unit kerb systems and other suitable units that are available and their suitable applications
  8. the importance of robust edge restraints
  9.  the importance of using the correct type of bed material
  10.  how the bed is placed and prepared, and how it is shaped to follow summits, hollows and transitions
  11.  the pros and cons of using fresh windrow bedding and pre-placed races
  12. how to calculate the number of units required
  13. how units should be stored on-site, how they are delivered to the laying face, and how they are positioned for the laying operative
  14.  the pros and cons of both butt-jointed and mortar-jointed installations
  15. how units are consolidated to the required line and level
  16. how edge restraints are checked for accuracy in alignment along both straights and curves
  17.  use of cutting tools including guillotine, saw and trimming tools
  18.  the importance of dust-suppression and respiratory protective equipment (RPE)
  19. the removal and replacement of defective units when using a cut-off saw
  20. the importance of maintaining communication with those involved in, or affected by, your work and how this should be done
  21.  the importance of following relevant environmental and ecological best practice to help minimise the impact of your work on the environment
  22. your responsibilities under relevant health and safety legislation, codes of practice and organisational policies
