Though relatively expensive, paving has the major advantage of requiring very little maintenance. By increasing the area of garden under paving, a resultant reduction in labour requirement can be achieved. Relative to any other garden feature, paving of any kind needs practically no work.
All kinds of paving need to be swept of debris and dust occasionally to prevent a build-up that would allow moss and weeds to grow, but this is a very light task compared with maintaining a similar area of lawn, for example.
Where there are cracks, or joints in the case of concrete slabs, weeds are likely to get established. These can be difficult to remove physically but there are many excellent products for their control, such as Hytrol, Pathclear or other path weedkiller, and Casoron G granules.
