Note: All full colour images in this web site are as accurate as your screen will allow. It is advised that these colours should be verified against actual natural stone samples.

Note: After laying light coloured paving on site, care should be taken to protect from dirt and detritus while the remaining construction works are completed.

Installation guidelines

Preparation

Sub-grade:

  • Clear top-soil: complete sub-grade drainage.
  • Excavate and back-fill soft spots: compact well throughout.
  • Protect sub-grade from adverse weather.
  • Lay geotextile fabric or capping layer (if specified/required).

Sub-base:

  • Prepare in accordance with Specification for Highway Works.
  • Lay and compact in layers to a close-textured finish.
  • Open-textured sub-bases may require a binding layer of finer material.

Laying

General principles:

Lay paving immediately on prepared bedding: do not leave bedding exposed to weather or overnight.

To avoid bedding layer damage and creep, lay paving units up slopes and/or away from edge restraints.

Stand on previously laid paving when placing next row.

Block and sett paving

Lay fine aggregate bedding course (to BS EN 12620 Gf85 0/4 mp) to a final compacted thickness of 50 mm (in accordance with BS 7533: Part 3).

This can be done by either:

  1. Compacting 50 mm of fine aggregate and screeding a further 15-20 mm of loose fine aggregate. (A small trial area may be required to determine the actual surcharge). Note: this is the preferred method. If laying on a roadbase or previously paved area, recommended thicknesses are reduced to 30 mm followed by 9-14 mm.

    Or:

  2. 60-70 mm loose fine aggregate screeded to accept blocks. Note: 39-44 mm if laying on a roadbase or previously paved area.
  • Lay blocks hand tight (2-5 mm joints).
  • Bed blocks with vibrating plate compactor (2 or 3 passes typically required).
  • Brush-fill joints with fine dry sand (in accordance with BS 7533: Part 3).
  • Vibrate surface again to assist joint filling.

If necessary during early life, top-up joints with loose sand to within 1 mm of working face by brushing surface.

 

For Countrysetts (pedestrian):

  • Lay setts in traditional stretcher bond with 6-10 mm width joints.
  • Ram well into bedding.
  • Cut setts as necessary for obstructions etc. (minimum cut lengths: 75 mm): dress top arris of cut pieces with a lump hammer to give rounded top edge.
  • Fill top joints with limestone dust (approx. 3-4 mm down) and ram down.
  • Alternatively, use weak dry sand/cement mix, 1:9 mix).

    Note: to prevent mortar staining, keep setts dry during joint filling.

  • Sweep clean, then moisten with watering can fitted with a medium rose.

 

For Countrysetts (vehicular-cube):

  • Lay as traditional granite setts on minimum 100 mm of ST1 concrete.
  • Bed on 25 mm Class 1 mortar with 6-10 mm class 1 mortar joints.

 

For Woburn:

  • Lay setts in Herringbone pattern if heavy duty (80 mm) version is specified for regular/heavy traffic applications.
  • Complete as for block paving.
