Slip formed kerbs are a fantastic idea but I'm not sure if it will suit your driveway. For starters it is expensive (not sure of rates), there are set up costs (and "mobilisation" charges)which mean it can only be justified on substantial runs of kerbing, where these initial set up costs are quickly dissipated. Also aesthetically you need to consider how a slip formed kerb would look. They are are big and designed to resist damage by heavy good vehicles, will it look OTT and crude in a domestic driveway? Just a few things to consider...
