Macmat® is a geomat made from a three-dimensional matrix of UV stabilized, non-degradable synthetic fibres, heat bonded where they cross, extruded onto a double twisted steel woven mesh. The reinforcing hexagonal double twisted steel wire mesh has mechanical characteristics greater than the ones recommended in EN 10223-3. The steel wire is with heavily galvanised and may also be protected with an extruded polymeric coating for greater protection.
Used on vulnerable soil slopes, exposed to erosion, MacMat® immediately increases the soil’s resistance to erosion by providing an environment that enhances the growth of vegetation through the mat. Quality topsoil is brushed into the 3-d matrix of the mat following installation. It is also used within water courses to provide hydraulic erosion protection. The MacMat® is secured to the ground using suitable pins / stakes as required in the project. Its most common use however, is within soil nailed slopes; the soil nails provide the overall slope reinforcement with the MacMat® providing surface strengthening and support between the nail heads.
