These paved front driveway tiles came with the house when I bought it. Some
of the tiles are cracking and some spliting due to frost damage, (in London,
U.K.).

Underneath the tiles is very solid and sound and I have no reason to disturb
it. I would like to do something to improve the appearence, preferably
without incurring any big expense or digging up these glazed tiles.

Laying a coating of cement on top would be difficult for me and I think
would not look so good. I'm looking for a fairly easy method within the
capabilities of a layman if possible. Thanks for any suggestions.
