By using a thick layer of anti-corrosive base course materials and selecting suitable plantation (seeds?), the VCC technology can provide a sustainable ecological system on slopes. It is suitable for application to rock and/or concrete on steep slopes, and has been adopted in hundreds of projects in mainland China. With regard to the 30-40° slopes on both side of the section between Salak Selatan and Putrajaya toll stations of the Maju Expressway, and taking into account of local rainfalls which is many times than that in China, the VCC technology is most suitable for the ecological restoration of these slopes.
The construction with VCC technology will engage 6 sets of machinery and 6 teams, it will take 4 months for the construction and another 3 months for curing. Normal traffic will not be affected (by this construction work).
