    A hybrid retaining wall system was implemented, combining Maccaferri Green Terramesh reinforced soil slopes with a concrete panel retaining wall. The design incorporated 70-degree Green Terramesh reinforced slopes on three sides of the approach ramps, while a vertical concrete panel wall was used where space limitations required a more compact solution.<\/p>\n

    In total, 240 metres of Green Terramesh retaining wall were installed, reaching heights of up to 8 metres at the railway crossing. This reinforced soil solution provided the required steep slope stability while enabling rapid construction within a tight programme.<\/p>\n

    To minimise traffic disruption, the construction was carefully phased. The northbound retaining walls were completed first, allowing traffic to continue flowing, before switching to the southbound side with managed one-way traffic systems.<\/p>\n

    A key advantage of the Green Terramesh system is its ability to support vegetation growth. During installation, the topsoil behind the facing units was seeded with a selected vegetation mix. This allowed rapid establishment of greenery, creating a natural, environmentally sensitive finish. Over time, the structure has blended into the surrounding landscape, becoming largely concealed beneath vegetation.<\/p>\n

    The project successfully delivered a bridge widening solution that met structural, environmental, and logistical requirements. The use of Green Terramesh reinforced slopes provided a sustainable retaining wall system that combined engineering performance with aesthetic value, while minimising disruption in a busy urban setting.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

    A hybrid retaining wall solution comprising 70-degree Maccaferri Green Terramesh reinforced slopes to three of the approach ramp faces and one concrete panel-faced wall where space restrictions required a vertical structure. A total length of 240m Green Terramesh wall was installed to a maximum height of 8m where the bridge crossed the railway line.<\/p>\n

    <\/p>\n

    The Green Terramesh reinforced slopes provided the required steep-faced green solution and were straightforward to install within the tight construction schedule. Traffic disruption was kept to a minimum by first completing the north-going walls before commencing the south-going and switching one-way traffic lanes accordingly.<\/p>\n<\/p>\n

    During the installation of the embankment walls, the topsoil wedge behind the face of the Green Terramesh embankment was impregnated with a selected seed mix and vegetation rapidly established to an extent where the structure is barely visible beneath the natural cover.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>
