In old or modern, natural stone is probably the most beautiful material for an aisle. Using salvage stones reduces its cost.
Dig two trenches 20 cm wide and 15 cm deep.
Mark the route with two lines.
If the land has a natural slope towards the house, provide a gutter to collect rainwater.
Make a medium concrete (250kg / m3). Fill the trenches and pave along the line.
Remove excess concrete that could interfere with the laying of other stones.
After drying (24h minimum), disburse the soil about 15 cm and spread a layer of building sand.
Grind using a martyr block or a groomer.
Start laying the stones in an opus uncertainty. Place the straightest edge along the edge.
Regularly check the alignment using a ruler.
Cut the stones if necessary with a hammer and chisel.
If you are using an angle grinder, bushhammer the cut to give it an irregular appearance.
Use stones of all sizes to maintain an even distribution over the entire length.
The joints (3 to 4 cm) must be as regular as possible.
Make the joints with a mortar made of 2 volumes of white cement, 1 volume of lime and 3 volumes of sand.
Firmly seal the joints with the cat’s tongue.
Wait a few hours for the mortar to set. Then brush the joints with a brush.
Be careful not to dig the joints too much.
