CLAY QUARRY EROSION CONTROL, FLOWERING AND RENATURATION.   What PRATI ARMATI® can do

  • 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 (geo-grids, geotextile meshes, 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;
  • subtracts up to 400% more CO2 than traditional plants, according to Kyoto Protocol;
  • 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.

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

Advantages 

  • very fast planting process (many hectars per day);
  • doesn’t need:
    • −        top soil (seeds can grow on any lithotype)
    • −        plastic and natural materials like geo-grids, geotextile meshes, 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  SOx  particulate)
    • – on-site working times and site-related risks
    • – up to 50% of economical costs

 

CLAY QUARRY EROSION CONTROL, FLOWERING AND RENATURATION.  Over the years and in different world areas, many techniques of slope protection and re-naturalization have been developed.

CLAY QUARRY EROSION CONTROL, FLOWERING AND RENATURATION.  Slope vegetation represents a quite innovative technique for the control and miti-gation of water erosion phenomena and, contextual-ly, may play a positive role in slope stability by simply considering that the plant roots act as special soil reinforcement.

CLAY QUARRY EROSION CONTROL, FLOWERING AND RENATURATION.  This aspect of soil vegetation gains much importance provided that herbaceous deep-roots – with high tensile strength properties – are well seated into the soil.
The role of vegetation in slope protection from erosion phenomena has been studied and document-ed throughout experimental investigations.

CLAY QUARRY EROSION CONTROL, FLOWERING AND RENATURATION.  Several approaches – based on theoretical models, physical or empirical models – have been proposed in the lit-erature for the quantitative evaluation of erosion (soil loss).Among these, it is worth to cite the Uni-versal Soil Loss Equation ‐ USLE (Wischmeier, 1976; Wischmeier and Smith, 1978).

CLAY QUARRY EROSION CONTROL, FLOWERING AND RENATURATION.  Amongst the consolidated techniques aimed at reducing soil and rock erosion developed in the years 1950-’60 and involving the use of manufactured products such as geonets, geogrids, fascines, special interest is to be paid to herbaceous plants characterized by deep roots – with great length (3 m) and extraordinary ten-sile strength – which may contribute to reduce ero-sion.

CLAY QUARRY EROSION CONTROL, FLOWERING AND RENATURATION.  In particular, the aerial portion of such herba-ceous grassy plants dissipates most of kinetic energy of rain drops, smoothing their erosive action; more-over, even when the plants are seasonally dried up, an important fraction of rain flows above the aerial portion of the vegetation in case of intense rainfalls. This eco-technique, obtained by seeding perennial herbaceous plants directly into the soil, is of simple and fast installation and does not require any maintenance.

CLAY QUARRY EROSION CONTROL, FLOWERING AND RENATURATION.  Recent studies, also supported by bot-anists, agronomists, naturalists and geologists, have highlighted the ability of many herbaceous species to effectively contrast erosive phenomena, even in bare and sterile soils where other common species do not succeed to vegetate.
The implantation of grassy species, made of deep and thin roots with large tensile strength, may repre-sent an interesting technique also for the improve-ment of slope equilibrium conditions, limitedly to shallow and potentially unstable soil masses.

CLAY QUARRY EROSION CONTROL, FLOWERING AND RENATURATION.  In or-der to assess the additional important role played by slope vegetation, the soil-roots interaction needs to be specifically analyzed from a mechanical and a hydraulic point of view. Some of these aspects are dealt with in the following paragraphs. The subject is complex since several phenomena are involved in the soil/vegetation interaction and their study re-quires specific skills in various fields such as hy-draulics, agronomy, soil physics, in addition to soil mechanics.

CLAY QUARRY EROSION CONTROL, FLOWERING AND RENATURATION.  From a theoretical point of view, the mass balance equations must be respected in the po-sition of the problem, by taking into due considera-tion the concurring phenomena of soil evaporation, plant transpiration, water runoff along the slope, wa-ter infiltration into the soil and water uptake fromMechanical and hydraulic effects of deep root.
