Kerbs, including channels, quadrants, angles etc. are intended to separate surfaces at the same or at different levels to provide a physical and visual delineation or containment. They also provide a separation between surfaces submitted to different kinds of traffic. To improve visual contrast between surfaces, for example between footpaths and roadways, kerb units may be painted. These painted kerbs are not clearly visible to the motorist during wet conditions, especially at night.
The units are manufactured with an integrated surface reflective-mix to provide an economic and more effective alternative to painted kerbs.
Naturally occurring stone pavers are mined from quarries, or collected from a rock outcrop. Because they are not manufactured, as concrete and brick pavers are, sto ne pavers have different qualities than concrete and brick and are often more expensive than their manufactured cousins. But, they are still the most popular choice for all external paving needs.
