We tend to use plastic-based gullies, and chambers in the footway. Has anyone got broader experience of using plastic kerbing? I’ve used them once (the kerb-drain type), and they haven’t altered in the 5 years they’ve been installed far. I was expecting some element of deterioration, but they haven’t been damaged or faded/peeled – they’re just as they were. Surely a good alternative to the resource intensive pcc type for many locations?
