Pre-Seeded Erosion Control Blankets

The Greenfix Covamat Plus range is made up of biodegradable 10-15mm thick quilted pre-seeded erosion control blankets that are available in either 100% straw, 50% straw and 50% coir, or 100% coir. There is a choice of seed mix from any of our six standard mixes, including wildflower, as well as the opportunity to include site-specific seed mixes. Giving protection against surface erosion, the different fibre combinations and reinforced meshes offer short, medium, and long-term degradations (up to 36 months).

Covamat Plus improves poor soil conditions with the addition of organic fertiliser and micro-organisms. Once the Covamat has been laid and irrigated the dehydrated and granulated fertiliser material serves as a natural slow-release nutrient source.

Covamat F3

The Greenfix F3 product range combines all the benefits of Covamat, Eromat, Mulchmat and Rockmat with additional fire protection according to DIN 4102-1.
In prolonged hot and dry periods some fibres quickly become dry and at risk of catching fire from a spark or cigarette. In areas where fire hazards need to be considered, such as railway embankments, the Greenfix F3 range offers un-seeded and pre-seeded options.

Greenfix F3 range:

  • Covamat F3 pre-seeded erosion control blanket, used for fast establishment on a variety of slopes and embankments
  • Rockmat F3 un-seeded or pre-seeded blanket with the addition of a steel mesh for increased reinforcement and prevention of burrowing animals
  • Mulchmat F3 dual layered mulch mat provides nursery like conditions for newly planted trees and shrubs
  • Eromat F3 un-seeded erosion control blanket which can be under-seeded with site-specific seed mixes.
