Teracro

Product catalog summary

Overview: The document discusses the teracro® geosynthetic structure, designed to prevent soil erosion and aid in landscaping and development works. It highlights the use of ridged geosynthetic structures to retain topsoil and manage water runoff effectively.

Specifications: The teracro® mat features 7cm high ridges that act as filtering barriers, allowing water to pass while retaining topsoil. It is a non-woven retention sheet with twisted horizontal strips bonded on a strong mat. The product is delivered in rolls, 5m wide and 50m long, and is light, flexible, and easy to transport.

Technical Advantages: The structure is strong and flexible, with ridges that filter water and prevent erosion. It helps retain moisture and regulates water supply to vegetation. The mat is designed to absorb forces exerted by the earth layer and transmit them to the anchor trench and slope.

Applications: Suitable for motorway banks, reservoir banks, flood-prone slopes, dump covering, embankment revegetation, and protection of watertight basins and dumps.

Installation Procedure: The product is anchored at the uphill end, with no intermediate pegging required. Panels are unrolled from the top downwards, overlapping sides by 0.50m. The anchor trench and toe mound are filled and compacted, and topsoil is laid from the top downwards.

Mechanical and Hydraulic Properties: The document provides detailed specifications, including normal permeability, filter mesh size, flow rate capacity, mass per unit area, nominal thickness, tensile strength, maximum deformation, and punching strength.

Recommendations: It is advised to conduct a preliminary design before selecting a product and to contact teragéos for guidance. The document emphasizes the importance of using the correct anchor system for specific profiles.

Catalog excerpts

Preventing soil erosion, carrying out development works and landscaping with topsoil often involve the use of ridged geosynthetic structures. Ridges several centimetres high, perpendicular to the slope, play a vital role as filtering barriers by allowing runoff to pass but at the same time retaining the layer of topsoil. These ridges holdԓ the layer of topsoil on the slope and considerably attenuate gully formation. The force exerted by the earth layer as it tries to slide downhill is absorbed by the textile ridges, which are themselves fixed to the teracro > geosynthetic mat. The mat is designed...
