Environmental solutions > Degraded areas

		Loaned, dump, escavated, mined, silted and eroded non-vegetated sites are named degraded areas. These sites require recovery - as mandated by law - and as a voluntary company measure for certification and business protection purposes. There are many techniques for recovering degraded areas. Technicians should know each alternative, consider efficiency, safety and cost and suggest the best solution. Rudimentary techniques are expensive and inefficient as they require constant reworking. International standard hidrosowing (the use of large infill material volumes) and anti-erosion biodegradable blankets, among other methods, have demonstrated excellent results in degraded areas.

	. 1. Completely eroded non-vegetated slope; easily erodable sandy soil requiring immediate protection to avoid further erosion. 2. Site visit after application of the plant screen Plant Screen® 1000IC showing visual improvement. 3. View of the same site one year after Bioengineering Technique confinement measures were implemented.





	. 1. General view of erosion gullies to be recoved using Bioengineering Techniques and biodegradable products. 2. Recovery services at an advanced stage; complete surface and deep drainage, erosion gully recovery and application of anti-erosion biodegradable blankets. 3. Same site three months later; notice the efficiency of the method, no erosion gullies and a completely re-vegetated area.





	. 1. General view of the degraded area showing soil preparation. A highly erodable and sterile material, reaching high summer temperatures. 2. The green patch in this picture was a pilot test. When the customer was assured of the results, a Biotextile Screen® 600BP anti-erosion biodegradable blanket was applied over the slopes. 3. View of the same site after re-vegetation, showing continuous and complete protection and no erosion gullies after much rain. The impression is one of no past human interference.
