Before ordering your paving, ensure that you have as precise an idea as possible of what you are planning to create. Without this being an absolute rule, the usual width for footpaths is 3 feet (90 cm), and 8-1/2 feet (2.60 m) for driveways.
To give you an idea of your future paving project and set out its definitive positioning, dust the planned location with plaster powder or chalk. Once everything is laid out, measure the surface to pave. As paving stones are sold in square meters, you just need to provide the total surface of the paving when you place your order.
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:
