Installation guidelines

Design standards

All installations should be detailed and constructed in accordance with BS7533: Part 3 and Part 6.

Haunching

All kerbing should normally be haunched with concrete to ensure full stability and support for adjacent paving and to help withstand occasional vehicular impact.

HGV Kerb

Sub-grade
As for adjoining paved areas.
Sub-base
Material: granular sub-base type 1.
Compacted depth: 150 mm min.
Bedding and haunching
Material: concrete (grade ST1).

Note: When using HGV with dowel holes, it is necessary to lay the kerbs on a fresh concrete kerb race and hammer the dowel bars into the race after unit is placed. The holes should then be grouted as specified by the engineer.

Detailing

Radii:
Select from 36/12, 11/7, 6/4.5, 3, 2, or 1.5 metre radius units to form required radius kerb-line.

Angles:
Select 45°, 60°, or 90° quadrants as required.

Transitions:
Use 2-component transitions between HGV kerb and standard HB2 kerbing.
