A consistent approach to finishes

9.1.15External works

External works, including drives and paths, shall have appropriate finishes.

Drives and paths should be:

  • within a maximum ±10mm deviation measured using a 2m straight edge with equal offsets; however, localised falls into gulleys and channels are acceptable.
  • designed and constructed to minimise the potential for standing water.

One hour after rain has stopped, areas of temporary standing water should not be deeper than 5mm or exceed 1m². Temporary standing water is not permitted adjacent to entrance doors.

Also note:

  • Displacement and variations in surface levels, including scuffing and pitting, may arise due to settlement, natural ground movement and traffic.
  • When checking flatness, the slope required for drainage on drives should be taken into account.

Drainage covers should:

  • align with the adjacent ground or surface finish (for channels, the cover should be set below the adjacent ground)
  • be positioned so that the difference in height between the cover and adjacent hard surfaces allows for future settlement.
