Typical applications include:

• Coastal Protection
• Dams and Flood Defence Bunds
• River and Canal Bank Protection
• River Revetments
• Culvert Head Walls
• Structured Causeways
• Cliff Protection
• Bridge abutments
• Submerged breakwaters
• Artificial Islands

Natural vegetation can provide a certain level of erosion protection, it is often inadequate on steep slopes or areas prone to wave run-up or intermittent high velocity flows. This can occur in coastal areas, rivers, lakes, reservoirs, drainage ditches, flood bunds and overspill ponds.

River and canal banks are subject to wave action creating reverse flow conditions, it is this dynamic erosive force that undermines bank stability and affects channel flow and navigability.

The hydraulic and filtration properties of Terram Geotextiles allows them to be highly effectively when used in place of traditional filter layers. Typically, a single layer of geotextile fabric can replace a succession of stone filter layers. A single bedding layer of stone is laid on the geotextile, to carry the rock armour that resists erosion caused by variable hydraulic forces.

Design Considerations

• Soil conditions
• Hydrology
• Hydrogeology

Terram Geocomposites can play an important role in your erosion control application providing drainage, reinforcement or separation to the design.

Terram has a broad range of 'off the shelf' geocomposite products to cover most applications. However we are proud of our ability to manufacture bespoke products to suit specific applications for your project.

At Terram we have forty years of experience of manufacturing geosynthetics for demanding applications throughout the global civil engineering industry. We know how important it is that the materials you choose to use will perform consistently and reliably throughout the life of the project.

Bespoke manufacturing is a new approach to manufacturing geosynthetics that harnesses our extensive knowledge of a wide range of geosynthetic solutions and marries their specific properties to solve your problem.

Geotextiles, geogrids and geomembranes are just some of the products that have combined into geocomposite products answering the specific problems of our customers; whether it be soil reinforcement, ground stabilisation, filtration, drainage, protection or erosion control.

Our technical development team will work with you to develop your bespoke solution in our facility in South Wales. The product is developed to your specification then tested to ensure product performance before being signed off for use in your application. If you're not sure what specification you need then our technical team will work with you to understand the problem before developing the solution.

Typical applications include:

• Cut or fill embankments
• Dams or spillways
• Abutment protection
• Landfill lining, covers and drainage
• Steep slopes
• Soil nailing cover.

Terram Geocell can be used in many erosion control applications often eliminating complicated and expensive construction techniques. Its three dimensional structure provides a blanket of 'cells' on the slope surface which can contain a variety of infill materials depending on the application; either topsoil, aggregates, from sands and gravels to larger stones and cobbles, and concrete of various strengths and surface finishes. This greatly improves resistance to erosive forces such as rainwater run-off on steep or unstable slopes, or slopes exposed to severe hydraulic or ­­­­mechanical stresses.

Design Considerations

• Slope angle
• Slope drainage
• Slope length
• Slope substrate
• Hydrology
• Required finish on slope
