Rapid Changes in Grade
Rapid changes in gradients are always difficult, particularly when utilising a large dimensional paving unit.
To accommodate these changes in grade and ensure that the finished
project is aesthetically pleasing with zero 'lipping' of paver edges,
the paver unit dimension requires altering.
This may be achieved by simply specifying a smaller paver size in the
area of gradient change. Incorporating this smaller unit size in the
overall layout and design of the project will create a pleasing
featuring that will enhance the overall appearance of the pavescape.
Alternatively, creating a 'cut line' at the point of gradient change
within the paving body will accommodate the deflection required to
eliminate unnecessary 'lipping' of paver edges.
When the paving is laid on 45 o bond, this 'cut line' at the point of
gradient change may be accomplished by installing UrbanStone 45 o paving
halves - thus avoiding unnecessary cutting residue, waste and cost.
A typical example of an area requiring the installation of a gradient
change line would be at the pavement pram-ramp entry and exit as
demonstrated in the adjacent illustration.
