BLUE-GREY MARLS CLAYS AND FLYSCH at 900m in southern Italy

BLUE-GREY MARLS CLAYS AND FLYSCH at 900 m: Basilicata region. These are very dificulty litotypes and climates to be regreened and flowered, stopping erosion

BLUE-GREY MARLS CLAYS AND FLYSCH at 900m in Basilicata region (southern Italy) are litotypes very difficult to tackle also due to hard climate conditions

Synthesis of  PRATI ARMATI®  Technology

BLUE-GREY MARLS CLAYS AND FLYSCH

Erosive phenomena are very diffused all over the world. Over the years different techniques of ground protection and renaturation have been developed. Among them, an outstanding and innovative natural technology uses only natural perennial grass plants with deep roots and allows to operate in areas where pedoclimatic conditions were until a few years ago considered prohibitive for the development of vegetation. Such technology also appears promising with respect to phenomena of surface instability of fronts: the deep root grasses may induce mechanical and hydraulic effects on slope equilibrium that typically increase the shear strength of soil. The mechanical effects of plant roots result from the root/soil interaction processes; the hydraulic effects derive from the significant reduction of water content and degree of saturation of soil caused by the presence of grass. Erosion phenomena and surface instability events of slopes may be effectively contrasted by vegetal blankets with deep root systems. Such technology, simply consisting on seeding perennial grasses, appears effective, quick to realize and does not require any maintenance. It is recognized that an efficient protection (deep roots and strong aboveground vegetation) may affect mechanical and hydraulic conditions of the slope, which in turn would influence the equilibrium conditions of potentially sliding surface portions of soil.

What are  PRATI ARMATI®

BLUE-GREY MARLS CLAYS AND FLYSCH

This is a guaranteed full service, based on seeds of herbaceous perennial deep rooting plants capable to grow on almost any lithotype and climate, contrasting EROSION even on most barren ground types, re-naturalizing slopes, favouring biodiversity and accelerating ecological succession, protecting civil infrastructure and restoring polluted areas. 

Where you can use PRATI ARMATI®

BLUE-GREY MARLS CLAYS AND FLYSCH

  • ridges and banks of motorways, roads and railways;
  • shores of lakes, rivers, torrents and channels;
  • seashores;
  • quarries, mines, landfill sites and contaminated lands. 

PRATI ARMATI®  can be used in combination with

BLUE-GREY MARLS CLAYS AND FLYSCH

All traditional or environmental engineering solutions (like gabions, terramesh, fences, reinforced ground, rockfall protection netting) used to stabilize the slope, to improve the environmental impact. 

What PRATI ARMATI® can do 

BLUE-GREY MARLS CLAYS AND FLYSCH

  • stop erosion and desertification.
  • the seeds  grow on every sterile lithotype  (compact clay, altered or fractured rocks,  soils polluted by hydrocarbons  and heavy metals, even in concentrations 10 times above the legally permitted limits, lime added soils up to 5% in weight) without topsoil, plastic and natural materials (geonets, geogrids, geocells, geotextile meshes, biomats, natural fibre nets, mulch, bonded wood-fibre matrices, and so on);
  • if the above materials are already on-site, they can hide them, increasing their performances and landscape benefits;
  • mitigate the environmental impact of conventional civil works;
  • mutual and synergic protection of conventional civil infrastructure, reducing maintenance works;
  • accelerate the re-naturalization process;
  • increase soil shear resistance and safety factor;
  • protect and waterproof the slope  in case of heavy rainfall event;
  • protect from fractures and rifting;
  • reduce soil saturation;
  • thrive even in soils polluted with high levels of heavy metals: lead, chrome, zinc, nickel, copper, mercury, cadmium, arsenic, cobalt, antimony, selenium, and so on;
  • isolate polluting soils. Prevents the dispersion of polluting dusts via water and wind (transportation in suspension, via infiltration and wind-borne deflation).
  • change a fragile ground in a plastic “soil-roots” system. 

Advantages  of  PRATI ARMATI®  Technology

BLUE-GREY MARLS CLAYS AND FLYSCH

  • very fast planting process (many hectars per day);
  • doesn’t need:
  1. top soil (seeds can grow on any lithotype)
  2. plastic and natural materials like geonets, geogrids, geotextile meshes, biomats, natural fibre nets, mulch, bonded wood-fibre matrices, and so on;
  • safety planting process;
  • natural and non-toxic materials, simple and safety machines;
  • maintenance works like irrigation, fertilization and grass cutting are not neccessary;
  • protects water capturing and control systems (e.g. drainage systems, ditches, trench drains), keeping them clean and efficient, avoiding clogging and eliminating maintenance works;
  • antierosion efficiency improves over time;
  • re-profile work of the slope needs (if it is possible) only a course-grained soil surface finish;
  • a zero-maintenance technique;
  • able to facilitate re-naturalization and ecological succession by incorporating any desired seed of flowers, shrubs or trees;
  • able to capture CO2 up to 400% more than common grassy plants
  • capable to reduce, with respect to traditional techniques:
    • up to 100 times the weight of required materials
    • up to 10 times the energy requirements
    • up to 10 times polluting emissions (CO2  CO  NOx  SO particulate)
    • on-site working times and site-related risks
    • up to 50% of economical costs.

BLUE-GREY MARLS CLAYS AND FLYSCH

Blue-grey marls clays and flysh are present in Basilicata region (Southern Italy), specifically ​​in the Val d’Agri area and in the surrounding valleys at an average height of 900 m. The slopes based on these litotypes are very difficult to tackle in order to stop erosion and to improve their appearance making them green and flowered, also due to the extreme climates conditions:  cold winters with lots of snow, and hot summers. The area  experienced several landslides and mudslides, both superficial and deep.
