RETENTION WORKS FOR JOJOBERA GU EXPANSION

Keeping in mind all the aspects of project, the client decided to go with Maccaferri’s products. Considering the scope of project and client’s requirements, Maccaferri proposed reinforced soil slope using Terramesh® and Green Terramesh® system which is convenient, less time consuming and ends up as an aesthetically pleasing structure. Terramesh® system consists of gabion basket facia units with an integrated double twist mesh as reinforcing element. These walls are easier to construct and more cost effective compared other conventional systems especially for very high structures. In this project, the base of Terramesh® wall was located at 1m below to achieve the necessary embedment. Terramesh® has stone facing and Green Terramesh® has a grass cover at the face to sync with the natural environment. Non-woven geotextile was used behind the Terramesh® units in order to act as a separator and filter, which allowed free movement of water and also prevented any backfill sand to come out of the voids in between the stones. A 300mm thick layer of vegetative soil with manure and grass roots was placed at the face of Green Terramesh® units. The height of retention varied form 5m to 7m.
