Surveying stake
A surveying stake or survey post is made of wood or plastic, usually has a rectangular cross-section and is pointed at the bottom and marked in color at the top. They are used, for example, to mark boundary stones after a cadastral survey or positions, i.e. corners and courses of measured areas, lines or distances, for example individual properties after a land consolidation . Often these pegs are also renewed to ensure that certain points can be found again. They are especially important when grass has grown over boundary stones.
Pegs can be driven into almost any unsealed ground with a suitably heavy hammer or stone, dry hard ground can be pre-drilled with a pointed iron rod.
Driving in a surveying nail with a head diameter of about 25 mm is recommended for asphalt and joints in a street pavement. For soil there are galvanized nails with a head diameter of 80 mm made of curved sheet metal and a welded shaft made of steel tube with a diameter of 20 mm and a length of about 300 mm. Both variants are galvanized, are driven in almost flush and can easily be driven over or passed over.
In concrete or rock, we recommend pre-drilling with a pneumatic hammer drill, which has been available with battery operation for several years. Hand stone drills for 6–10 mm diameter and hammers are somewhat lighter and, thanks to muscle power, work completely independently. In hard rock any drilling is difficult.
Shape and color
The surveying pegs customary in Germany are mostly rectangular with a cross section of 24 mm × 44 mm or 18 mm × 46 mm and a length of 300–1000 mm. Surveying pegs are usually made of softwood and are four-faced at the bottom. The surface is occasionally planed on one side to enable later writing with a waterproof felt pen.
In Austria, the surveying marks, including boundary marks (including pegs) set on the basis of surveying work, must be left in place and thus neither damaged nor removed.
In Australia the surveying stake is usually square (50 mm in urban areas and 75 mm in rural areas) and protrudes between 50 and 100 mm from the ground. It is usually white and often bears the ticket number in black.
