It makes no difference how well a pavement or driveway have been laid, all pavings, from the very top-of-the-range to the bottom, require some basic maintenance. There is no maintenance-free paving of one form or another. Maintenance keeps paving in prime condition, lack of maintenance allows paving to deteriorate.
Even if it’s just a basic wash-down with soapy water, all types and forms of paving will look so much better, while certain types of paving tend to need a bit more care and attention to ensure they always look as smart as possible. The good news is that cleaning is usually easy and even the most decrepit, neglected or abused pavement or driveway can often be given a new lease of life with just a little effort.
