Geocomposite for steep slope stabilisation
Maccaferri
MacMat®R is a three-dimensional geomat that can be applied as an erosion control mat for sloped embankments, channel linings and soil-veneer applications. It was developed to meet the need for an erosion control material which was both strong and environmentally acceptable. MacMat®R is manufactured with a double twist steel wire mesh reinforcement inside the geomat, to provide tensile strength and a stronger form of erosion protection to better ensure the stability of the topsoil on roadway embankments, channels linings and other areas susceptible to erosion damages.
MacMat® R has several advantages:
The continuity of the lining is easily achieved by lacing the edges together with binding wire or metal rings without overlapping and minimising the wastage.
In many standard situations a simple fold into the top of the slope of an anchor trench could be used, being wooden stakes or other anchors sufficient to anchor the wire mesh to the ground.The double twist wire mesh protects the geomat from any potential damage limiting those to a single mesh opening.
The steel reinforcement provides high stiffness to the geocomposite and an uniform adherence to the subsoil providing better protection of the covered surface.
It may be easily fixed to any thicker lining or bottom protection (gabions, mattresses, etc.) providing a better and continuous protection and anchorage where the erosion is usually more critical or the stresses are concentrated.
The combined use of a geocomposite reduces to 50% the installation costs over a double layer system.
