It is common practice in South Africa to use a concrete foundation for precast concrete kerbs. This is recommended by Bosun.
It is important to fill expansion joints with a suitable sealant in order to prevent bedding and jointing material of segmented paving behind the kerbs seeping out of empty expansion joints.
Precast kerbs are commonly installed in combination with cast in situ channels. Bosun recommends the use of precast channels which eliminates many issues caused by cast in situ channels. However, if channels are cast in situ, precast kerbs should be covered in order to protect them against concrete splatter. It is also recommended to protect kerbs against asphalt splatter.
