The most effective way of controlling erosion on an embankment is to establish vegetation. Erosion control blankets are often used to promote germination of seeds, to enable a strong grass sward and root matrix to establish quickly.
One erosion control blanket which is used for this purpose is the pre-seeded Covamat Fresh. Fully biodegradable, Covamat Fresh adds a 5mm layer of topsoil to the existing organic fertilisers, dry micro-organisms and selected grass seeds incorporated within the blanket.
The addition of a top soil layer allows the incorporated grass seeds to start to germinate almost immediately meaning that the Covamat Fresh range has the fastest germination speed of any pre-seeded biodegradable erosion control blanket.
Covamat Fresh is available in different fibre combinations and reinforced meshes for short, medium and long-term degradation of up to 36 months. Covamat Fresh is specially designed for freshly-soiled inherently stable embankments, new slope cuttings, lake edgings and facing reinforced soil slopes.
One of the many advantages of Covamat Fresh is the ability to protect seeds from wind and rain, and over Winter, allowing germination when conditions allow. When matched with Greenfix Bio-stakes, made from potato and wheat starch, which leave behind only water and Humus, the environmental impact of Covamat Fresh is effectively zero.
Covamat Fresh can be supplied either with a choice of six standard seed mixes or with your own choice of locally sourced or special application seed mixes including wildflowers.
Projects that can benefit from Covamat Fresh include housing and commercial schemes where the rapid establishment of a grassed surface will promote the amenity value of an area. Similarly, it is ideal for landscaping work where presenting the client with an attractive completed job is essential.
The Covamat Fresh range offers the flexibility of suitable fibre combinations and grass seed for any site without leaving a legacy of plastic behind.
