Renaturation of a limestone quarry

Renaturation of a limestone quarry


Renaturation of a limestone quarry in Spoleto (Umbria region) implemented on almost vertical rocky walls, without watering or use of top soil.

The range of grounds that can be treated with PRATI ARMATI®  include all the soils and rocks that, thanks to characteristics such as fracturing grade, macrostructure, texture, granulometry, compactness etc., allow development of root apparatus, for example:


• clays
• silts
• sands
• gravel

and any mixture of these materials in different proportions



• conglomerates (slightly cemented)
• marls (weathered)
• Limestone (slightly cemented)
• flysch
• pyroclastites
• schists
• acid or basic rocks altered or highly fractured

Root development may be obtained even in soils that in pedological terms are sterile.

PRATI ARMATI® take root also in lime added soils (up to 5% in weight).

Rocks must be altered or fractured to a sufficient extent, and the percentage of success in root development is proportional to the degree of alteration and fracturing.

On compact and undamaged rocks root development is impossible.


Which pedoclimatic conditions PRATI ARMATI® can withstand

  • adaptable to extreme soil and climatic conditions within a temperature range of –45°C to +60°C, resistant within a pH range between pH 4 and pH 11
  • climates from  very dry to very wet;
  • on practically any lithotype and climate, even on most barren ground types: clay, silt, sands, gravel, flysh, lime added soils, granular soil ridges without top soil, and so on;
    • on soils polluted by hydrocarbons and heavy metals;
  • on salty soil


Installation limits

The areas in which the intervention using PRATI ARMATI® is carried out shall therefore:

  • be stable from the geotechnical viewpoint (SF>1.3) and shall therefore, if necessary, undergo stabilization using conventional civil engineering techniques;
  • have a maximum angle of inclination of 60° and shall therefore be re-profiled if necessary;
  • have a course-grained soil surface finish;
  • have appropriate works for the channelling of surface and groundwater.

    An example of this difference between quarrying and mining would be that limestone is quarried whereas the mineral lime is mined. The word quarry can also

    Limestone quarrying is usually the process by which this valuable sedimentary stone that is the limestone is removed from the ground. Limestone is used in the.
