** Longevity depends on location factors, soil- water- and climate conditions as well as on the local risk of erosion on site.
Installation:
Vegetation Establishment– Seeding can be undertaken prior to blanket installation and seedlings can grow up through the blanket. Alternatively seeding can undertake after installation and sown on to the blanket.

Hydro seeding is also an effective seed application method over large areas and will provide further support for vegetation growth. Wildflower and aquatic plants and shrubs can be inserted through the coir mesh after installation and the blanket will provide support to vegetation establishment.
Overlapping and Anchorage –Sufficient overlap and anchorage is the key to the success of erosion control blanket products.
