Thanks for your replies chaps, appreciated. Sadly weed killer is not an option for me, but the cement solution appears to be working fine albeit with a fair amount of time and effort - and dry weather - required.
Indeed, no skip near me is safe, although I have found it definitely pays to speak to the owner beforehand - mainly as a courtesy, but also to get a hint at what might yet be dug out. When they learn what I am up to with their rubble, they are invariably interested, and they seem to then take more pains to remove these blocks, paviours, slabs etc without breaking them! More often than not they are interested enough to want to come and see for themselves what the railway looks like, as actually happened yesterday.
By contrast I tend not to ask permission of the people who set off fireworks, as they obviously had no great concerns about where their spent rockets fell to earth anyway, so the sticks are fair game! Darned fine building material they are, too.
