If pre-cast kerbs are laid to form roads at this stage, time and money are lost at a later date due to replacement of damaged kerbs so that local authorities may adopt roads. One method of overcoming the problem of kerb damage is to lay a ‘kerb race’.
The Kerblay technique of extruding a kerb race mechanically, with an upstand at the front to retain the road formation and a ‘key’ slot at the rear to retain the backing, is the most suitable shape, and it overcomes the expensive formwork otherwise required for this shape.
