A wide range of erosion control mats are available on the market however these fall into two basic categories for most applications – those with a biodegradable element and those entirely made from polymer that are designed to last longer. In reality mosterosion control mats are there to permit a cover of vegetation to be established and maintained. In the majority of cases it is that vegetation which provides most of the beneficial effect with respect to erosion prevention. So when selecting an erosion control product we should be considering what we can encourage to grow there, how long it will take to establish and how we can maintain that growth through the seasons.
The use of erosion control mats will be beneficial in the following application areas:
• River banks and wetlands
• Lake/ reservoir shores
• Earth dams
• Revetments and balancing ponds
• Landfill caps
• Embankments & slopes (e.g. road & rail)
• Noise bunds
• River bed/spill way protection
Biodegradable Erosion Mats
TCS offer a standard range of biodegradable erosion control mattings. The Techmat biodegradable range includes open weave jute and coir mats for short to mid-term cover (12 – 36 months) and denser blanket products consisting of 100% coir and 50/50 mix of straw and coir or 100% straw mixes.
Techmat P ‘permanent’
When correctly pinned in place and filled with top soil Techmat type P provides excellent intimate contact with the underlying soil thereby encouraging growth through the mat. As the vegetation establishes the roots become entwined within and through the structure of the Techmat type P thereby helping to secure the vegetation and inhibit erosion of the underlying soil.
• Non-biodegradable & longer lasting
• Environmentally inert
• Robust but flexible
• Light and simple to install
• Assists establishment of permanent vegetation
