Paving care: how to keep the stone beautiful for years
Moss, sunken stones and empty joints: most paving problems are preventable. A simple year-round care plan.
Properly installed paving lasts for decades, but without care it loses its looks within a couple of years: the stone darkens, moss and weeds grow in the joints, and the surface turns slippery in the rain.
The spring wash
Once a year, usually in spring, the paving deserves a proper wash. Professional pressure washing or thermal washing removes moss, algae and the general grey film. A household pressure washer handles light dirt, but the wrong nozzle and too much pressure can damage the stone surface.
Joints are the backbone of paving
After every wash, the joints must be refilled with fresh sand. Empty joints mean the stones start to move and the edges begin to chip. It is worth using special jointing sand that compacts and suppresses weed growth.
Moss prevention
Moss loves moisture and shade. If the paving is constantly wet, check the slope and drainage. A protective treatment applied after washing slows down new moss growth for 2 to 3 years.
Winter caution
Granite chips are safer for the stone than salt: overdosing salt leaves white stains on concrete pavers and speeds up surface erosion. Push snow with a rubber-edged blade, not a bare metal one.
If your terrace or driveway has already gone mossy, we do a professional wash with joint sanding, usually within one day.
