Land preparation and maintenance before the autumn rains

virens-Interventions for the control of soil erosion

Land preparation and maintenance before the autumn rains


The sharp variations in climate that we have witnessed in recent months and the unpredictability associated with rainfall remind us with increasing urgency of the need and importance of maintaining our land in the best possible condition, in order to be ready to face not only extreme weather events of short duration, but also prolonged periods of bad weather.

Despite the fact that nowadays it is more and more complex to predict these sudden climatic changes, autumn remains a period characterised by a large amount of precipitation; this is why it is essential to take preventive measures to ensure effective land preparation and maintenance.
What are the main actions that should be taken to ensure successful soil preparation through preventing erosion?

  • First of all, a regular flow in the watercourses must be ensured to protect their banks and embankments;
  • It is necessary to carry out regular cleaning and maintenance;
  • Areas that have been stripped of their original vegetation must be consolidated and greened;
  • As well as reducing the use of concrete and land consumption.

Different types of products for different types of situations


As part of these activities to protect the land and prevent hydrogeological and erosion risk, various types of techniques and materials are generally used, including bio-mesh, geo-mesh, bio-mats, bio-textiles, geo-grids, geo-cells and geo-composites.

Among this wide range, Virens' products are the only pre-seeded materials to be available both in a biodegradable version, i.e. temporary, and in a permanent version, i.e. with synthetic or metallic components.

Having both the technical and vegetative solution for protecting, consolidating and greening surfaces in a single product is a considerable advantage in terms of the final result and operability of the intervention.

Moreover, Virens products are customised in terms of seeds, fertiliser, etc., offering the possibility to cope with different situations with the best possible greening tools, such as bio-textiles, geo-textiles and geo-composites, all pre-seeded and designed to grass and vegetate any type of soil surface.

Virens bio-textiles


Our Viresco® Sator belongs to the biotextiles/biofelts category. Composed entirely of cellulose-derived fibres, it completely biodegrades in about 4-5 months, and being very thin (approx. 4mm) it adheres perfectly to the ground, preventing underlying seepage and offering excellent surface erosion protection.

Our Viresco® Sator biotextile firmly retains seeds and fertiliser in the mesh, even under extreme conditions and inclinations, ensuring uniform greening and ideal ecological and landscape results.
It is widely used for lining and protecting natural and artificial earthen slopes or embankments, including watercourses, for erosion control and the protection of seeds from runoff, as well as to ensure more favourable conditions for them to take root and grow.
But that's not all, it is in fact recommended for all critical situations in construction, in landscaping, in the greening of landfills, reclaimed land, quarries, in geotechnics, as a fine particle retentor and as a matrix for grassing façades of strengthened and reinforced soil.

 


Virens Geomats


Virmat belongs to the category of geo-mats, available in a heavier structured version (Virmat) and a lighter, more manageable version (Virmat L).

These are three-dimensional, anti-erosive gripping geo-mats, which again are the only ones of this type of product that are pre-seeded.

They consist of the combination of a high-tenacity, three-dimensional geo-mat with the Viresco pre-seeded biotextile, and provide robust slope protection on the one hand, and quick grassing and reinforced root anchorage to the soil and three-dimensional structure on the other. The result is a single, vigorous block capable of resisting the strongest erosive forces.

Virmats can also be applied at very steep angles, up to 70°, and are able to perform an effective protective and vegetative action.
A solution particularly suitable in all the situations and contexts listed above and in particular characterised by:
  • slopes of significant height
  • very steep slopes
  • watercourses banks and beds
  • very loose slopes
  • poor soils
  • poorly irrigated escarpments.

 The RecsViresco geo-composite


Also belonging to the category of geo-composites is RecsViresco, the latest addition to Virens' range of erosion control pre-seeded products.

The result of combining a double-twist wire mesh with the pre-seeded Viresco® Sator biotextile, it is designed for erosion control and vegetative covering of steeply sloping soils or soils that are exposed to erosion and surface instability.

The metal reinforcing element has a permanent function of containing and absorbing the deformational stresses that develop on the surface of the soil mass, but on its own it does not offer the necessary protection against erosion of the medium-to-fine fraction of the soil. To achieve this, the combination of pre-seeded biotextile with high greening capacity well anchored to the soil by the wire mesh itself is very useful.

RecsViresco is used for:
  • immediate erosion control of the slope surface and fine soil parts;
  •  regular and uniform plant establishment and growth;
  •  erosion protection and soil seeding in a single step without the need for sowing before or after laying;
  •  greater speed of execution of the work;
  • excellent environmental compatibility from a physical-chemical point of view;
  •  landscape improvement associated with the securing of critical slopes.
The choice of Virens products may vary depending on the slope of the terrain, as it is necessary to diversify the proposal as the slope increases:
  • Viresco® Sator works well on slopes up to 45 degrees.
  • Virmat L works well on slopes up to 45-55 degrees.
  • Virmat works well on slopes up to 55-70 degrees.
  • RecsViresco works well on slopes up to 60-70 degrees.
