Longitudinal Levelling and Profiles

Levelling out means setting a terrain or work level from an initial height or exit. This levelling shows the difference between the points.

Levelling out is used to resolve the unknown qualities of altimetric differences, setting work platform height, water discharge slopes in public byways, differences in piping, levelling out motorways, football pitches, dykes, breakwaters, airport runways, flagstones, etc.

Longitudinal profiles are plans showing the altimetric differences of one trajectory or two concrete points, which demonstrate different partial slopes and distances and at the origin of the track (trajectory).

These profiles are used as a reflection of the behaviour of the terrain both in architecture (house-building, terraces and agricultural terracing) and in engineering (layout projects for public highways, drains, etc.).
