Terramesh® System and Green Terramesh® are modular systems used to form rock and vegetated (green) faced soil reinforced slopes (also known as Mechanically Stabilised Earth).
Terramesh® System consists of pre-assembled units of double twisted, heavily galvanised and polymer coated wire mesh (8×10 type, wire diameter 2.2 mm or 2.7 mm). The facing section of the unit is formed by connecting a back panel and diaphragms to the main fascia unit, thus creating the rectangular shaped cells used for stone confinement. The geogrid reinforcement, fascia and lid are all one continuous panel of mesh. Terramesh® System units are supplied in standard lengths, requiring no cuts on site.
Green Terramesh® consists of pre-fabricated units of double twisted wire mesh (8×10 type, wire diameter 2.2 mm or 2.7 mm) lined with an erosion control blanket and stiffened with a welded mesh panel. Two pre-formed steel braces are supplied to be connected at the job site to maintain the unit to the required slope angle. The angled front face and the erosion control blanket are designed to facilitate the establishment of natural vegetation of the units; an important requirement of Green Terramesh®. As all components are factory fitted, Green Terramesh® is more rapid to install than competitor reinforced soil systems. The unit is simply erected on site, the bracing angles support the face at the designated angle without the need for any external formwork or shuttering.
Terramesh® System and Green Terramesh® have been used on the most significant infrastructure schemes has been used globally on some of the most significant infrastructure schemes, including what is believed to be the tallest reinforced soil structure in the world at 74m high.
On taller slopes and structures, Terramesh® System and Green Terramesh can be used in conjunction with our high performance primary geogrids, ParaLink®, ParaGrid®.
Technical Characteristics of the double twist wire mesh products TERRAMESH are listed and detailed in the technical data sheet available on Maccaferri website (https://www.maccaferri.com/ ). According to Construction Product Regulation CEE 305/2011 the essential technical characteristics, as per Harmonized Document EAD 200026-00-0102, are reported in the Declaration of Performances (DOP).
