    Cut slopes at Cisumdawu Toll Road (Phase II \u00e2\u0080\u0093 Tunnel Area) are prone to soil erosion due to its vulnerability to rainfall and lack of vegetation on the slope surface. The selection of proper material was necessary in order to provide an integrated and comprehensive solution. Erosion Control Solution by Maccaferri Indonesia was selected considering its ability to allow surface seepage and to grow vegetation (LCC \u00e2\u0080\u0093 Legume Cover Crop). Permanent Open Drainage (Vertical and Horizontal) is constructed on the cut slopes and it enhances controlling the surface water flow.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

    The inclination of the slopes is 45\u00c2\u00b0 degree (V:H = 1:1), referring to Public Works Ministry Specification \u00e2\u0080\u009cSpesifikasi Khusus Interim SKh-1.3.17 Pengendali Erosi Lereng\u00e2\u0080\u009d following the inclination of the slopes, the suitable material is \u00e2\u0080\u009cTipe II \u00e2\u0080\u0093 Selimut Pengendali Erosi Polimer\u00e2\u0080\u009d. Hence, the material MacMat EM was selected. MacMat EM is made from UV Stabilized HDPE Geomat. The polymeric Geomat controls surface soil erosion and helps to propagate vegetation. An array of mulching contained seeds was applied onto the MacMat EM to bring vegetation. Available in rolls of 2m x 30m, MacMat EM was installed with the support of a T-shape deformed bar to hold the material on the cut slopes. Erosion Control System by Maccaferri Indonesia has great advantages such as: \u00e2\u0080\u00a2 Easy and Convenient Installation; \u00e2\u0080\u00a2 Available for Combination with Soul Nailing for Slope Stabilization; \u00e2\u0080\u00a2 Allows drainage on the surface of the slope; \u00e2\u0080\u00a2 Vegetation as Rehabilitation; \u00e2\u0080\u00a2 Economically Competitive.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>","protected":false},"excerpt":{"rendered":"
