A rockfall hazard was discovered along Bts. Bandung/Cianjur – Naringgul – Cidaun Road due to weathered conditions of the rock slope that endangers the lives of the road users. Maccaferri Indonesia provided a rockfall barrier (RB 3000) to dissipate the energy of falling rocks of up to 3,000 kJ with 6 meters height and 25 meters total length.

The construction process of the Karalloe Dam resulted in many cut slopes that were vulnerable to surface erosion. The total area that needed to be protected during this project in total is approximately 14.400 m2 and to meet the owner’s needs, Maccaferri presents an erosion control solution that can replace the shotcrete system.
Due to its hilly topography, the Sampoerna Academy Sentul sports field was built on flat land as a result of slope cutting. Therefore, it is necessary to have slope protection to protect the area from potential landslides and erosion. Apart from having the main purpose of protecting the facilities and the users, green areas can provide good environmental value to make the area blend with nature yet protected.
As part of the dam construction, there was an existing river flow that needs to be diverted. The original design used heavy galvanizing as the coating of the wire mesh or concrete structure as the alternative. Maccaferri proposed the use of Gabions and Mattresses with PVC coating as a protection against river flow, abrasion, and UV exposure.
To increase nickel production capacity, it is necessary to build a new smelter in a limited area. The purpose of the retaining wall structure as a base foundation that is able to withstand loads of the new smelter construction.
The cut slopes at the Sindang Heula Dam require a solution that can overcome soil erosion. Maccaferri provided an erosion control called MacMat HS solution that capable of growing vegetation.
