INSTALLATION GUIDE
KERB INSTALLATION
DESIGN STANDARDS All installations should be detailed and constructed in accordance with BS 7533: 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.

Sub-grade As for adjoining paved areas. Sub-base Material: granular type 1. Compacted depth: 150mm min to suit application. Bedding and haunching Material: concrete (grade ST1). Minimum dimensions: (see Figs 1a and 1b). Transitions: use 1 or 2 component transition units as appropriate between Access kerb and standard HB2 kerbing.

Material: granular sub-base type 1. Compacted depth: 150mm min to suit application. Bedding and haunching Material: concrete (grade ST1) Minimum dimensions: (see Fig.2). 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 (see figs 3 and 4). 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.
