Paving stone maintenance
Things to remember:
Paving stones require hardly any maintenance; you simply need to wash them from time to time, but more often than not, rain will do the job adequately. You should also ensure that they are not overgrown by vegetation on the edges and in the joints.
Apart from that, the two main enemies for exterior paving are grease stains (motor oil) and moss, which tends to proliferate when your paving is moist. It is therefore rare to see moss grow when the paved surface features a sufficient slope for rain to run off naturally. You can get rid of moss by scraping it off or burning it with a blow torch, but for a more permanent result, you should use an anti-moss product available on the market. However, if you choose to use such a product, take care of surrounding vegetation which may also be affected.
In pictures
- Paving stone maintenance is limited to periodical cleaning with a brush and black soap.
- Then rinse abundantly with a water jet.
- If you don't have a lawnmower, cut the grass in the joints with small shears.
- Don't let your lawn invade your paving, push soil that rolls over onto the stone back underneath.
- Scrub stubborn stains with an abrasive stone (carborundum) or sand them off with a sanding disk.
- Remove moss by scrubbing vigorously with a hard brush and soapy water, or use a special anti-moss product.
Did you know?
Sedimentary rocks are the result of the accumulation and compacting of mineral debris (i.e. other stones), organic debris (animal remains and vegetation, fossils), or chemical precipitation.
They are exogenous rocks, i.e. rocks which are formed on the surface of the Earth. Sedimentary rocks are present on 75% of the surface of the Earth's continents, but when considering its crust as a whole (from the surface to a depth of 22 miles (35 km)), they only represent 5% of its total volume.
The main sedimentary rocks are:
- sandstone
- sand
- siltstone
- loess
- clay
- shale
- coal
- oil
- limestone
- chalk
- etc.
